|
|
10576
|
99 |

104 |
|
|
10576
|
105 |
Version 0.86 [January, 1996]
|
|
2
|
106 |
fixed bugs
|
|
|
107 |
improved documentation
|
|
|
108 |
|
|
10576
|
109 |
Version 0.87 [January, 1996]
|
|
2
|
110 |
fixed medium model bugs
|
|
|
111 |
fixed other bugs introduced in 0.85 and 0.86
|
|
|

added some minor documentation
|
|
|
113 |
|
|
10576
|
114 |
Version 0.88 [January, 1996]
|
|
2
|
115 |
fixed progressive bugs
|
|
|
116 |
replaced tabs with spaces
|
|
|
117 |
cleaned up documentation
|
|
|
118 |
added callbacks for read/write and warning/error functions
|
|
|
119 |
|
|
10576
|
120 |
Version 0.89 [July, 1996]
|
|
|
121 |
Added new initialization API to make libpng work better with shared libs
|
|
|
122 |
we now have png_create_read_struct(), png_create_write_struct(),
|
|
|
123 |
png_create_info_struct(), png_destroy_read_struct(), and
|
|
|
124 |
png_destroy_write_struct() instead of the separate calls to
|
|
|
125 |
malloc and png_read_init(), png_info_init(), and png_write_init()
|
|
|
126 |
Changed warning/error callback functions to fix bug - this means you
|
|
|
127 |
should use the new initialization API if you were using the old
|
|
|
128 |
png_set_message_fn() calls, and that the old API no longer exists
|
|
|
129 |
so that people are aware that they need to change their code
|
|
|
130 |
Changed filter selection API to allow selection of multiple filters
|
|
|
131 |
since it didn't work in previous versions of libpng anyways
|
|
|
132 |
Optimized filter selection code
|
|
|
133 |
Fixed png_set_background() to allow using an arbitrary RGB color for
|
|
|
134 |
paletted images
|
|
|
135 |
Fixed gamma and background correction for paletted images, so
|
|
|
136 |
png_correct_palette is not needed unless you are correcting an
|
|
|
137 |
external palette (you will need to #define PNG_CORRECT_PALETTE_SUPPORTED
|
|
|
138 |
in pngconf.h) - if nobody uses this, it may disappear in the future.
|
|
|
139 |
Fixed bug with Borland 64K memory allocation (Alexander Lehmann)
|
|
|
140 |
Fixed bug in interlace handling (Smarasderagd, I think)
|
|
|
141 |
Added more error checking for writing and image to reduce invalid files
|
|
|
142 |
Separated read and write functions so that they won't both be linked
|
|
|
143 |
into a binary when only reading or writing functionality is used
|
|
|
144 |
New pngtest image also has interlacing and zTXt
|
|
|
145 |
Updated documentation to reflect new API
|
|
|
146 |
|
|
|
147 |
Version 0.90 [January, 1997]
|
|
|
148 |
Made CRC errors/warnings on critical and ancillary chunks configurable
|
|
2
|
149 |
libpng will use the zlib CRC routines by (compile-time) default
|
|
10576
|
150 |
Changed DOS small/medium model memory support - needs zlib 1.04 (Tim Wegner)
|
|
|
151 |
Added external C++ wrapper statements to png.h (Gilles Dauphin)
|
|
|
152 |
Allow PNG file to be read when some or all of file signature has already
|
|
|
153 |
been read from the beginning of the stream. ****This affects the size
|
|
|
154 |
of info_struct and invalidates all programs that use a shared libpng****
|
|
|
155 |
Fixed png_filler() declarations
|
|
|
156 |
Fixed? background color conversions
|
|
|
157 |
Fixed order of error function pointers to match documentation
|
|
|
158 |
Current chunk name is now available in png_struct to reduce the number
|
|
|
159 |
of nearly identical error messages (will simplify multi-lingual
|
|
|
160 |
support when available)
|
|
|
161 |
Try to get ready for unknown-chunk callback functions:
|
|
|
162 |
- previously read critical chunks are flagged, so the chunk handling
|
|
|
163 |
routines can determine if the chunk is in the right place
|
|
|
164 |
- all chunk handling routines have the same prototypes, so we will
|
|
|
165 |
be able to handle all chunks via a callback mechanism
|
|
|
166 |
Try to fix Linux "setjmp" buffer size problems
|
|
|
167 |
Removed png_large_malloc, png_large_free, and png_realloc functions.
|
|
|
168 |
|
|
|
169 |
Version 0.95 [March, 1997]
|
|
|
170 |
Fixed bug in pngwutil.c allocating "up_row" twice and "avg_row" never
|
|
|
171 |
Fixed bug in PNG file signature compares when start != 0
|
|
|
172 |
Changed parameter type of png_set_filler(...filler...) from png_byte
|
|
|
173 |
to png_uint_32
|
|
|
174 |
Added test for MACOS to ensure that both math.h and fp.h are not #included
|
|
|
175 |
Added macros for libpng to be compiled as a Windows DLL (Andreas Kupries)
|
|
|
176 |
Added "packswap" transformation, which changes the endianness of
|
|
|
177 |
packed-pixel bytes (Kevin Bracey)
|
|
|
178 |
Added "strip_alpha" transformation, which removes the alpha channel of
|
|
|
179 |
input images without using it (not necessarily a good idea)
|
|
|
180 |
Added "swap_alpha" transformation, which puts the alpha channel in front
|
|
|
181 |
of the color bytes instead of after
|
|
|
182 |
Removed all implicit variable tests which assume NULL == 0 (I think)
|
|
|
183 |
Changed several variables to "png_size_t" to show 16/32-bit limitations
|
|
|
184 |
Added new pCAL chunk read/write support
|
|
|
185 |
Added experimental filter selection weighting (Greg Roelofs)
|
|
|
186 |
Removed old png_set_rgbx() and png_set_xrgb() functions that have been
|
|
2
|
187 |
obsolete for about 2 years now (use png_set_filler() instead)
|
|
10576
|
188 |
Added macros to read 16- and 32-bit ints directly from buffer, to be
|
|
|
189 |
used only on those systems that support it (namely PowerPC and 680x0)
|
|
|
190 |
With some testing, this may become the default for MACOS/PPC systems.
|
|
|
191 |
Only calculate CRC on data if we are going to use it
|
|
|
192 |
Added macros for zTXt compression type PNG_zTXt_COMPRESSION_???
|
|
|
193 |
Added macros for simple libpng debugging output selectable at compile time
|
|
|
194 |
Removed PNG_READ_END_MODE in progressive reader (Smarasderagd)
|
|
|
195 |
More description of info_struct in libpng.txt and png.h
|
|
|
196 |
More instructions in example.c
|
|
|
197 |
More chunk types tested in pngtest.c
|
|
|
198 |
Renamed pngrcb.c to pngset.c, and all png_read_<chunk> functions to be
|
|
|
199 |
png_set_<chunk>. We now have corresponding png_get_<chunk>
|
|
|
200 |
functions in pngget.c to get information in info_ptr. This isolates
|
|
|
201 |
the application from the internal organization of png_info_struct
|
|
|
202 |
(good for shared library implementations).
|
|
|
203 |
|
|
|
204 |

|
|
|
219 |
Added RFC 1152 [sic] date support
|
|
|
220 |

|
|
|
221 |
Added 2-bit grayscale gamma handling (Glenn R-P)
|
|
|
222 |
Added more typecasts. 65536L becomes (png_uint_32)65536L, etc. (Glenn R-P)
|
|
|
223 |
Minor corrections in libpng.txt
|
|
|
224 |

|
|
|
226 |
all configurable options can be selected from command-line instead
|
|
|
227 |
of having to edit pngconf.h (Glenn R-P)
|
|
|
228 |
Fixed memory leak in pngwrite.c (free info_ptr->text) (Glenn R-P)
|
|
|
229 |
Added more conditions for png_do_background, to avoid changing
|
|
|
230 |
black pixels to background when a background is supplied and
|
|
|
231 |
no pixels are transparent
|
|
|
232 |

|
|
|
528 |

|
|
587 |
png_get_header_ver() in png.c. Moved png_sig to png_sig_bytes in png.c and
|
|

588 |
eliminated use of png_sig in pngwutil.c. Moved the various png_CHNK arrays
|
|
|
589 |
into pngtypes.h. Eliminated use of global png_pass arrays. Declared the
|
|
|

available to applications (although none are used in libpng itself) when
|
|
|
592 |
PNG_NO_GLOBAL_ARRAYS is not defined or when PNG_GLOBAL_ARRAYS is defined.

|
593 |
Removed some extraneous "-I" from contrib/pngminus/makefile.std

|
|
|
603 |
PNG_USE_GLOBAL_ARRAYS is defined.

607 |
Added iCCP, iTXt, and sPLT support; added "lang" member to the png_text
|
|
|
608 |
structure; refactored the inflate/deflate support to make adding new chunks
|
|
|
609 |
with trailing compressed parts easier in the future, and added new functions
|
|
|
610 |
png_free_iCCP, png_free_pCAL, png_free_sPLT, png_free_text, png_get_iCCP,
|
|
|
611 |
png_get_spalettes, png_set_iCCP, png_set_spalettes (Eric S. Raymond).
|
|
|
612 |
NOTE: Applications that write text chunks MUST define png_text->lang
|
|
|
613 |
before calling png_set_text(). It must be set to NULL if you want to
|
|
|
614 |
write tEXt or zTXt chunks. If you want your application to be able to
|
|
|
615 |
run with older versions of libpng, use
|
|
|
616 |
|
|
|
617 |
#ifdef PNG_iTXt_SUPPORTED
|
|
|
618 |
png_text[i].lang = NULL;
|
|
|
619 |
#endif
|
|
|
620 |
|
|
|
621 |
Changed png_get_oFFs() and png_set_oFFs() to use signed rather than unsigned
|

Combined PNG_READ_cHNK_SUPPORTED and PNG_WRITE_cHNK_SUPPORTED macros into
|
|
|
624 |

|
|
|
625 |
macros, leaving the separate macros also available.
|
|
|
626 |
Removed comments on #endifs at the end of many short, non-nested #if-blocks.
|
|
10576
|
627 |

|
|
628 |
Version 1.0.5f [December 6, 1999]
|
|
2
|

|
640 |
|
|
|
641 |
Version 1.0.5h [December 10, 1999]
|
|
2
|
642 |
NOTE: regarding the note for version 1.0.5e, the following must also
|
|
|
643 |
be included in your code:
|
|
|
644 |
png_text[i].translated_key = NULL;
|
|
|
645 |
Unknown chunk handling is now supported.
|
|
|
646 |

659 |
Added png_free_hIST() function.
|
|
|
660 |

|
|
|
661 |
and to add some convenience macros for use with sCAL.
|
|
10576
|
662 |
|
|
|
663 |
Version 1.0.5j [December 21, 1999]
|
|
2
|
664 |

|
|
|
665 |
around buggy compilers.

|
|
666 |
Added new type "png_fixed_point" for integers that hold float*100000 values
|

|
671 |
member to distinguish among tEXt/zTXt/iTXt types. Added
|
|
|
672 |
PNG_ITXT_COMPRESSION_NONE (1) and PNG_ITXT_COMPRESSION_zTXt(2) macros.
|
|
|
673 |
The "Note" above, about backward incompatibility of libpng-1.0.5e, no
|
|
|
674 |
longer applies.
|
|
|
675 |
Fixed png_read|write_iTXt() to read|write parameters in the right order,
|
|
|
676 |
and to write the iTXt chunk after IDAT if it appears in the end_ptr.
|
|
|
677 |
Added pnggccrd.c, version of pngvcrd.c Intel assembler for gcc (Greg Roelofs)
|

|
|
|
690 |

2
|
701 |
Added png_free_PLTE() function, and modified png_set_PLTE() to malloc its
|
|
|
702 |
own memory for info_ptr->palette. This makes it safe for the calling

728 |
example.c, pngtest.c, and contrib programs to use this macro.
|
|
|
729 |
Revised some of the DLL-export macros in pngconf.h (Greg Roelofs)
|
|
|
730 |
Fixed a bug in png_read_png() that caused it to fail to expand some images

in pngget.c
|
|
|
734 |

|
|
|

hasn't already been allocated.
|
|
10576

|
|
2
|
805 |
Added png_pass-* arrays to pnggccrd.c when PNG_USE_LOCAL_ARRAYS is defined.
|
|
|
806 |
Relocated paragraph about png_set_background() in libpng.3/libpng.txt
|
|
|
807 |
and other revisions (Matthias Benckmann)
|
|
|
808 |
Relocated info_ptr->free_me, png_ptr->free_me, and other info_ptr and
|
|
|
809 |
png_ptr members to restore binary compatibility with libpng-1.0.5
|
|
|
810 |
(breaks compatibility with libpng-1.0.6).
|
|
10576
|
811 |
|
|
|
812 |
Version 1.0.6h [April 24, 2000]
|
|
2
|
813 |
Changed shared library so-number pattern from 2.x.y.z to xy.z (this builds
|
|
|
814 |
libpng.so.10 & libpng.so.10.6h instead of libpng.so.2 & libpng.so.2.1.0.6h)
|
|
|
815 |
This is a temporary change for test purposes.
|
|
10576
|
816 |
|
|
|
817 |
Version 1.0.6i [May 2, 2000]
|
|
2
|
818 |
Rearranged some members at the end of png_info and png_struct, to put
|
|
|
819 |
unknown_chunks_num and free_me within the original size of the png_structs
|
|
|
820 |
and free_me, png_read_user_fn, and png_free_fn within the original png_info,
|
|
|
821 |
because some old applications allocate the structs directly instead of
|
|
|
822 |
using png_create_*().
|
|
|
823 |
Added documentation of user memory functions in libpng.txt/libpng.3
|
|
|
824 |
Modified png_read_png so that it will use user_allocated row_pointers
|
|
|
825 |
if present, unless free_me directs that it be freed, and added description
|
|
|
826 |
of the use of png_set_rows() and png_get_rows() in libpng.txt/libpng.3.
|
|
|
827 |
Added PNG_LEGACY_SUPPORTED macro, and #ifdef out all new (since version
|
|
|
828 |
1.00) members of png_struct and png_info, to regain binary compatibility
|
|
|
829 |
when you define this macro. Capabilities lost in this event
|
|
|
830 |
are user transforms (new in version 1.0.0),the user transform pointer
|
|
|
831 |
(new in version 1.0.2), rgb_to_gray (new in 1.0.5), iCCP, sCAL, sPLT,
|
|
|
832 |
the high-level interface, and unknown chunks support (all new in 1.0.6).
|
|
|
833 |
This was necessary because of old applications that allocate the structs
|
|
|
834 |
directly as authors were instructed to do in libpng-0.88 and earlier,
|
|
|
835 |
instead of using png_create_*().
|
|
|
836 |
Added modes PNG_CREATED_READ_STRUCT and PNG_CREATED_WRITE_STRUCT which
|
|
|
837 |
can be used to detect codes that directly allocate the structs, and
|
|
|
838 |
code to check these modes in png_read_init() and png_write_init() and
|
|
|
839 |
generate a libpng error if the modes aren't set and PNG_LEGACY_SUPPORTED
|
|
|
840 |
was not defined.
|
|
|
841 |
Added makefile.intel and updated makefile.watcom (Pawel Mrochen)
|
|
10576
|
842 |
|
|
|
843 |
Version 1.0.6j [May 3, 2000]
|
|
2
|
844 |
Overloaded png_read_init() and png_write_init() with macros that convert
|
|
|
845 |
calls to png_read_init_2() or png_write_init_2() that check the version
|
|
|
846 |
and structure sizes.
|
|
10576
|
847 |
|
|
|
848 |
Version 1.0.7beta11 [May 7, 2000]
|
|
2
|
849 |
Removed the new PNG_CREATED_READ_STRUCT and PNG_CREATED_WRITE_STRUCT modes
|
|
|
850 |
which are no longer used.
|
|
|
851 |
Eliminated the three new members of png_text when PNG_LEGACY_SUPPORTED is
|
|
|
852 |
defined or when neither PNG_READ_iTXt_SUPPORTED nor PNG_WRITE_iTXT_SUPPORTED
|
|
|
853 |
is defined.
|
|
|
854 |
Made PNG_NO_READ|WRITE_iTXt the default setting, to avoid memory
|
|
|
855 |
overrun when old applications fill the info_ptr->text structure directly.
|
|
|
856 |
Added PNGAPI macro, and added it to the definitions of all exported functions.
|
|
|
857 |
Relocated version macro definitions ahead of the includes of zlib.h and
|
|
|
858 |
pngconf.h in png.h.
|
|
10576
|
859 |
|
|
|
860 |
Version 1.0.7beta12 [May 12, 2000]
|
|
2
|
861 |
Revised pngset.c to avoid a problem with expanding the png_debug macro.
|
|
|
862 |
Deleted some extraneous defines from pngconf.h
|
|
|
863 |
Made PNG_NO_CONSOLE_IO the default condition when PNG_BUILD_DLL is defined.
|
|
|
864 |
Use MSC _RPTn debugging instead of fprintf if _MSC_VER is defined.
|
|
|
865 |
Added png_access_version_number() function.
|
|
|
866 |
Check for mask&PNG_FREE_CHNK (for TEXT, SCAL, PCAL) in png_free_data().
|
|
|
867 |
Expanded libpng.3/libpng.txt information about png_data_freer().
|
|
10576
|
868 |
|

|
869 |

|
|
2
|
870 |
Changed pnggccrd.c and pngvcrd.c to handle bad adaptive filter types as
|
|
|
871 |
warnings instead of errors, as pngrutil.c does.
|
|
|
872 |
Set the PNG_INFO_IDAT valid flag in png_set_rows() so png_write_png()
|
|
|
873 |
will actually write IDATs.
|
|
|
874 |
Made the default PNG_USE_LOCAL_ARRAYS depend on PNG_DLL instead of WIN32.
|
|
|
875 |
Make png_free_data() ignore its final parameter except when freeing data
|
|
|
876 |
that can have multiple instances (text, sPLT, unknowns).
|
|
|
877 |
Fixed a new bug in png_set_rows().
|
|
|
878 |
Removed info_ptr->valid tests from png_free_data(), as in version 1.0.5.
|
|
|
879 |
Added png_set_invalid() function.
|
|
|
880 |

|
884 |
fewer error messages.
|
|
|
885 |
Rearranged checks for Z_OK to check the most likely path first in pngpread.c
|
|
|
886 |
and pngwutil.c.

|
|
887 |
Added checks in pngtest.c for png_create_*() returning NULL, and mentioned
|
|
|
888 |
in libpng.txt/libpng.3 the need for applications to check this.
|
|
|
889 |
Changed names of png_default_*() functions in pngtest to pngtest_*().
|
|
|
890 |
Changed return type of png_get_x|y_offset_*() from png_uint_32 to png_int_32.
|
|
|
891 |
Fixed some bugs in the unused PNG_INCH_CONVERSIONS functions in pngget.c
|
|
|
892 |
Set each pointer to NULL after freeing it in png_free_data().
|
|
|
893 |
Worked around a problem in pngconf.h; AIX's strings.h defines an "index"
|
|
10576
|
894 |
macro that conflicts with libpng's png_color_16.index. (Dimitri
|
|
|
895 |
Papadapoulos)
|
|
2
|
896 |
Added "msvc" directory with MSVC++ project files (Simon-Pierre Cadieux).

indexing in pngrutil.c and pngwutil.c to accommodate a buggy compiler.
|
|
|
903 |
Added a warning in png_decompress_chunk() when it runs out of data, e.g.
|
|
|
904 |
when it tries to read an erroneous PhotoShop iCCP chunk.
|
|
|
905 |
Added PNG_USE_DLL macro.
|
|
|
906 |
Revised the copyright/disclaimer/license notice.

Version 1.4.0rc01 [October 19, 2009]

|
|
|

|
|
2485 |
Added PNG_DEPSTRUCT, PNG_DEPRECATED, PNG_USE_RESULT, PNG_NORETURN, and
|
|
|
2486 |
PNG_ALLOCATED macros to detect deprecated direct access to the
|
|
|
2487 |
png_struct or info_struct members and other deprecated usage in
|
|
|
2488 |
applications (John Bowler).
|
|
|
2489 |
Updated scripts/makefile* to add "-DPNG_CONFIGURE_LIBPNG" to CFLAGS,
|
|
|
2490 |
to prevent warnings about direct access to png structs by libpng
|
|
|
2491 |
functions while building libpng. They need to be tested, especially
|
|
|
2492 |
those using compilers other than gcc.
|
|
|
2493 |
Updated projects/visualc6 and visualc71 with "/d PNG_CONFIGURE_LIBPNG".
|
|
|
2494 |
They should work but still need to be updated to remove

2495 |
references to pnggccrd.c or pngvcrd.c and ASM building.
|
|
|
2496 |
Added README.txt to the beos, cbuilder5, netware, and xcode projects warning
|
|
|
2497 |
that they need to be updated, to remove references to pnggccrd.c and

|
|
2498 |
pngvcrd.c and to depend on pngpriv.h
|
|
|
2499 |
Removed three direct references to read_info_ptr members in pngtest.c
|
|
|
2500 |
that were detected by the new PNG_DEPSTRUCT macro.
|
|
|
2501 |
Moved the png_debug macro definitions and the png_read_destroy(),
|
|
|
2502 |
png_write_destroy() and png_far_to_near() prototypes from png.h
|
|
|
2503 |
to pngpriv.h (John Bowler)
|
|
|
2504 |
Moved the synopsis lines for png_read_destroy(), png_write_destroy()
|
|
|
2505 |
png_debug(), png_debug1(), and png_debug2() from libpng.3 to libpngpf.3.

2507 |
Version 1.4.0beta94 [November 9, 2009]

|
2511 |

|
|
|
2516 |

|
|
|
2517 |
Corrected the png_get_IHDR() call in contrib/gregbook/readpng2.c
|
|
|
2518 |
Changed pngminim/*/gather.sh to stop trying to remove pnggccrd.c and pngvcrd.c
|
|
|
2519 |
Added dependency on pngpriv.h in contrib/pngminim/*/makefile
|
|
|
2520 |

|
|
|
2522 |
Renamed scripts/makefile.wce to scripts/makefile.cegcc

|
|
2523 |

so that only PNG_EXPORT functions are exported.
|
|
|
2525 |
Removed the deprecated png_check_sig() function/macro.
|
|
|
2526 |
Removed recently removed function names from scripts/*.def
|
|
|
2527 |
Revised pngtest.png to put chunks in the same order written by pngtest
|
|
|
2528 |
(evidently the same change made in libpng-1.0beta54 was lost).
|
|
|
2529 |
Added PNG_PRIVATE macro definition in pngconf.h for possible future use.
|
|
|
2530 |
|
|
|
2531 |

|
|
2532 |

Moved libpng-config.in and libpng.pc-configure.in out of the scripts
|
|
|
2542 |
directory, to libpng-config.in and libpng-pc.in, respectively, and
|
|
|
2543 |
modified Makefile.am and configure.ac accordingly. Now "configure"
|
|
|
2544 |
needs nothing from the "scripts" directory.
|
|
|
2545 |
Avoid redefining PNG_CONST in pngconf.h
|
|
|
2546 |
|
|
|

|
2569 |
Restored the PNG_WRITE_FLUSH_AFTER_IEND_SUPPORTED guard around the call
|
|
|
2570 |
to png_flush() after png_write_IEND(). See 1.4.0beta32, 1.4.0beta50
|
|
|
2571 |
changes above and 1.2.30, 1.2.30rc01 and rc03 in 1.2.41 CHANGES. Someone
|
|
|
2572 |
needs this feature.
|
|
|
2573 |
Make the 'png_jmpbuf' macro expand to a call that records the correct
|
|
|
2574 |
longjmp function as well as returning a pointer to the setjmp
|
|
|
2575 |
jmp_buf buffer, and marked direct access to jmpbuf 'deprecated'.
|
|
|
2576 |

|
|
2583 |
Use fast integer PNG_DIVIDE_BY_255() or PNG_DIVIDE_BY_65535()
|
|
|
2584 |
to accomplish alpha premultiplication when
|
|
|
2585 |
PNG_READ_COMPOSITE_NODIV_SUPPORTED is defined.
|
|
|
2586 |
Changed "/255" to "/255.0" in background calculations to make it clear
|
|
|
2587 |
that the 255 is used as a double.

|
|
2588 |
|
|
|
2589 |

|
2598 |
instead of in $prefix/include/libpng. Also revised makefile.sco
|
|
|
2599 |

|
|

2601 |
|
|
|
2602 |

Removed leftover "-DPNG_CONFIGURE_LIBPNG" from contrib/pngminim/*/makefile
|
|
|
2604 |
Relocated png_do_chop() to its original position in pngrtran.c; the
|
|
|
2605 |
change in version 1.2.41beta08 caused transparency to be handled wrong

Pass bit_depth=8 to png_build_gamma_table() when bit_depth is 16 but the
|
|

PNG_16_TO_8 transform has been set, to avoid unnecessary build of 16-bit
|
|
|
2612 |
tables.

|
|
2614 |

unclosed if-statement warning (Philip Lowman).
|
|
|
2648 |
Revised Makefile.am and Makefile.in to remove references to Y2KINFO,

Revised png_decompress_chunk() to improve speed and memory usage when
|
|
|
2668 |
decoding large chunks.
|
|
|
2669 |
Added png_set|get_chunk_malloc_max() functions.
|
|
|
2670 |
|
|
|
2671 |
Version 1.4.1beta05 [January 26, 2010]
|
|
|
2672 |
Relocated "int k" declaration in pngtest.c to minimize its scope.
|
|
|
2673 |
|
|
|
2674 |
Version 1.4.1beta06 [January 28, 2010]
|
|
|
2675 |
Revised png_decompress_chunk() to use a two-pass method suggested by
|
|
|
2676 |
John Bowler.
|
|
|
2677 |
|
|
|
2678 |
Version 1.4.1beta07 [February 6, 2010]
|
|
|
2679 |
Folded some long lines in the source files.
|
|
|
2680 |
Added defineable PNG_USER_CHUNK_CACHE_MAX, PNG_USER_CHUNK_MALLOC_MAX,
|
|
|
2681 |
and a PNG_USER_LIMITS_SUPPORTED flag.
|
|
|
2682 |
Eliminated use of png_ptr->irowbytes and reused the slot in png_ptr as
|
|
|
2683 |
png_ptr->png_user_chunk_malloc_max.
|
|
|
2684 |
Revised png_push_save_buffer() to do fewer but larger png_malloc() calls.
|
|
|
2685 |
|
|
|
2686 |
Version 1.4.1beta08 [February 6, 2010]
|
|
|
2687 |
Minor cleanup and updating of dates and copyright year.
|
|
|
2688 |
|
|
|
2689 |
Version 1.5.0beta01 [February 7, 2010]
|
|
|
2690 |
Moved declaration of png_struct into private pngstruct.h and png_info
|
|
|
2691 |
into pnginfo.h
|
|
|
2692 |
|
|
|
2693 |
Version 1.4.1beta09 and 1.5.0beta02 [February 7, 2010]
|
|
|
2694 |
Reverted to original png_push_save_buffer() code.
|
|
|
2695 |
|
|
|
2696 |
Version 1.4.1beta10 and 1.5.0beta03 [February 8, 2010]
|
|
|
2697 |
Return allocated "old_buffer" in png_push_save_buffer() before
|
|
|
2698 |
calling png_error(), to avoid a potential memory leak.
|
|
|
2699 |
Updated configure script to use SO number 15.
|
|
|
2700 |
|
|
|
2701 |
Version 1.5.0beta04 [February 9, 2010]
|
|
|
2702 |
Removed malformed "incomplete struct declaration" of png_info from png.h
|
|
|
2703 |
|
|
|
2704 |
Version 1.5.0beta05 [February 12, 2010]
|
|
|
2705 |
Removed PNG_DEPSTRUCT markup in pngstruct.h and pnginfo.h, and undid the
|
|
|
2706 |
linewrapping that it entailed.
|
|
|
2707 |
Revised comments in pngstruct.h and pnginfo.h and added pointers to
|
|
|
2708 |
the libpng license.
|
|
|
2709 |
Changed PNG_INTERNAL to PNG_EXPOSE_INTERNAL_STRUCTURES
|
|
|
2710 |
Removed the cbuilder5 project, which has not been updated to 1.4.0.
|
|
|
2711 |
|
|
|
2712 |
Version 1.4.1beta12 and 1.5.0beta06 [February 14, 2010]
|
|
|
2713 |
Fixed type declaration of png_get_chunk_malloc_max() in pngget.c (Daisuke
|
|
|
2714 |
Nishikawa)
|
|
|
2715 |
|
|
|
2716 |
Version 1.5.0beta07 [omitted]
|
|
|
2717 |
|
|
|
2718 |
Version 1.5.0beta08 [February 19, 2010]
|
|
|
2719 |
Changed #ifdef PNG_NO_STDIO_SUPPORTED to #ifdef PNG_NO_CONSOLE_IO_SUPPORTED
|
|
|
2720 |
wherever png_snprintf() is used to construct error and warning messages.
|
|
|
2721 |
Noted in scripts/makefile.mingw that it expects to be run under MSYS.
|
|
|
2722 |
Removed obsolete unused MMX-querying support from contrib/gregbook
|
|
|
2723 |
Added exported png_longjmp() function.
|
|
|
2724 |
Removed the AIX redefinition of jmpbuf in png.h
|
|
|
2725 |
Added -D_ALLSOURCE in configure.ac, makefile.aix, and CMakeLists.txt
|
|
|
2726 |
when building on AIX.
|
|
|
2727 |
|
|
|
2728 |
Version 1.5.0beta09 [February 19, 2010]
|
|
|
2729 |
Removed -D_ALLSOURCE from configure.ac, makefile.aix, and CMakeLists.txt.
|
|
|
2730 |
Changed the name of png_ptr->jmpbuf to png_ptr->png_jmpbuf in pngstruct.h
|
|
|
2731 |
|
|
|
2732 |
Version 1.5.0beta10 [February 25, 2010]
|
|
|
2733 |
Removed unused gzio.c from contrib/pngminim gather and makefile scripts
|
|
|
2734 |
Removed replacement error handlers from contrib/gregbook. Because of
|
|
|
2735 |
the new png_longjmp() function they are no longer needed.
|
|
|
2736 |
|
|
|
2737 |
Version 1.5.0beta11 [March 6, 2010]
|
|
|
2738 |
Removed checking for already-included setjmp.h from pngconf.h
|
|
|
2739 |
Fixed inconsistent indentations and made numerous cosmetic changes.
|
|
|
2740 |
Revised the "SEE ALSO" style of libpng.3, libpngpf.3, and png.5
|
|
|
2741 |
|
|
|
2742 |
Version 1.5.0beta12 [March 9, 2010]
|
|
|
2743 |
Moved "#include png.h" inside pngpriv.h and removed "#include png.h" from
|
|
|
2744 |
the source files, along with "#define PNG_EXPOSE_INTERNAL_STRUCTURES"
|
|
|
2745 |
and "#define PNG_NO_PEDANTIC_WARNINGS" (John Bowler).
|
|
|
2746 |
Created new pngdebug.h and moved debug definitions there.
|
|
|
2747 |
|
|
|
2748 |
Version 1.5.0beta13 [March 10, 2010]
|
|
|
2749 |
Protect pngstruct.h, pnginfo.h, and pngdebug.h from being included twice.
|
|
|
2750 |
Revise the "#ifdef" blocks in png_inflate() so it will compile when neither
|
|
|
2751 |
PNG_USER_CHUNK_MALLOC_MAX nor PNG_SET_CHUNK_MALLOC_LIMIT_SUPPORTED
|
|
|
2752 |
is defined.
|
|
|
2753 |
Removed unused png_measure_compressed_chunk() from pngpriv.h and libpngpf.3
|
|
|
2754 |
Moved the 'config.h' support from pngconf.h to pngpriv.h
|
|
|
2755 |
Removed PNGAPI from the png_longjmp_ptr typedef.
|
|
|
2756 |
Eliminated dependence of pngtest.c on the private pngdebug.h file.
|
|
|
2757 |
Make all png_debug macros into *unterminated* statements or
|
|
|
2758 |
expressions (i.e. a trailing ';' must always be added) and correct
|
|
|
2759 |
the format statements in various png_debug messages.
|
|
|
2760 |
|
|
|
2761 |
Version 1.5.0beta14 [March 14, 2010]
|
|
|
2762 |
Removed direct access to png_ptr->io_ptr from the Windows code in pngtest.c
|
|
|
2763 |
Revised Makefile.am to account for recent additions and replacements.
|
|
|
2764 |
Corrected CE and OS/2 DEF files (scripts/png*def) for symbols removed and
|
|
|
2765 |
added ordinal numbers to the Windows DEF file and corrected the duplicated
|
|
|
2766 |
ordinal numbers on CE symbols that are commented out.
|
|
|
2767 |
Added back in export symbols that can be present in the Windows build but
|
|
|
2768 |
are disabled by default.
|
|
|
2769 |
PNG_EXPORT changed to include an 'ordinal' field for DEF file generation.
|
|
|
2770 |
PNG_CALLBACK added to make callback definitions uniform. PNGAPI split
|
|
|
2771 |
into PNGCAPI (base C form), PNGAPI (exports) and PNGCBAPI (callbacks),
|
|
|
2772 |
and appropriate changes made to all files. Cygwin builds re-hinged to
|
|
|
2773 |
allow procedure call standard changes and to remove the need for the DEF
|
|
|
2774 |
file (fixes build on Cygwin).
|
|
|
2775 |
Enabled 'attribute' warnings that are relevant to library APIs and callbacks.
|
|
|
2776 |
Changed rules for generation of the various symbol files and added a new
|
|
|
2777 |
rule for a DEF file (which is also added to the distribution).
|
|
|
2778 |
Updated the symbol file generation to stop it adding spurious spaces
|
|
|
2779 |
to EOL (coming from preprocessor macro expansion). Added a facility
|
|
|
2780 |
to join tokens in the output and rewrite *.dfn to use this.
|
|
|
2781 |
Eliminated scripts/*.def in favor of libpng.def; updated projects/visualc71
|
|
|
2782 |
and removed scripts/makefile.cygwin.
|
|
|
2783 |
Made PNG_BUILD_DLL safe: it can be set whenever a DLL is being built.
|
|
|
2784 |
Removed the include of sys/types.h - apparently unnecessary now on the
|
|
|
2785 |
platforms on which it happened (all but Mac OS and RISC OS).
|
|
|
2786 |
Moved the Mac OS test into pngpriv.h (the only place it is used.)
|
|
|
2787 |
|
|
|
2788 |
Version 1.5.0beta15 [March 17, 2010]
|
|
|
2789 |
Added symbols.chk target to Makefile.am to validate the symbols in png.h
|
|
|
2790 |
against the new DEF file scripts/symbols.def.
|
|
|
2791 |
Changed the default DEF file back to pngwin.def.
|
|
|
2792 |
Removed makefile.mingw.
|
|
|
2793 |
Eliminated PNG_NO_EXTERN and PNG_ALL_EXTERN
|
|
|
2794 |
|
|
|
2795 |
Version 1.5.0beta16 [April 1, 2010]
|
|
|
2796 |
Make png_text_struct independent of PNG_iTXt_SUPPORTED, so that
|
|
|
2797 |
fields are initialized in all configurations. The READ/WRITE
|
|
|
2798 |
macros (PNG_(READ|WRITE)_iTXt_SUPPORTED) still function as
|
|
|
2799 |
before to disable code to actually read or write iTXt chunks
|
|
|
2800 |
and iTXt_SUPPORTED can be used to detect presence of either
|
|
|
2801 |
read or write support (but it is probably better to check for
|
|
|
2802 |
the one actually required - read or write.)
|
|
|
2803 |
Combined multiple png_warning() calls for a single error.
|
|
|
2804 |
Restored the macro definition of png_check_sig().
|
|
|
2805 |
|
|
|
2806 |
Version 1.5.0beta17 [April 17, 2010]
|
|
|
2807 |
Added some "(long)" typecasts to printf calls in png_handle_cHRM().
|
|
|
2808 |
Documented the fact that png_set_dither() was disabled since libpng-1.4.0.
|
|
|
2809 |
Reenabled png_set_dither() but renamed it to png_set_quantize() to reflect
|
|
|
2810 |
more accurately what it actually does. At the same time, renamed
|
|
|
2811 |
the PNG_DITHER_[RED,GREEN_BLUE]_BITS macros to
|
|
|
2812 |
PNG_QUANTIZE_[RED,GREEN,BLUE]_BITS.
|
|
|
2813 |
Added some "(long)" typecasts to printf calls in png_handle_cHRM().
|
|
|
2814 |
Freeze build-time only configuration in the build.
|
|
|
2815 |
In all prior versions of libpng most configuration options
|
|
|
2816 |
controlled by compiler #defines had to be repeated by the
|
|
|
2817 |
application code that used libpng. This patch changes this
|
|
|
2818 |
so that compilation options that can only be changed at build
|
|
|
2819 |
time are frozen in the build. Options that are compiler
|
|
|
2820 |
dependent (and those that are system dependent) are evaluated
|
|
|
2821 |
each time - pngconf.h holds these. Options that can be changed
|
|
|
2822 |
per-file in the application are in png.h. Frozen options are
|
|
|
2823 |
in the new installed header file pnglibconf.h (John Bowler)
|
|
|
2824 |
Removed the xcode project because it has not been updated to work
|
|
|
2825 |
with libpng-1.5.0.
|
|
|
2826 |
Removed the ability to include optional pngusr.h
|
|
|
2827 |
|
|
|
2828 |
Version 1.5.0beta18 [April 17, 2010]
|
|
|
2829 |
Restored the ability to include optional pngusr.h
|
|
|
2830 |
Moved replacements for png_error() and png_warning() from the
|
|
|
2831 |
contrib/pngminim project to pngerror.c, for use when warnings or
|
|
|
2832 |
errors are disabled via PNG_NO_WARN or PNG_NO_ERROR_TEXT, to avoid
|
|
|
2833 |
storing unneeded error/warning text.
|
|
|
2834 |
Updated contrib/pngminim project to work with the new pnglibconf.h
|
|
|
2835 |
Added some PNG_NO_* defines to contrib/pngminim/*/pngusr.h to save space.
|
|
|
2836 |
|
|
|
2837 |
Version 1.5.0beta19 [April 24, 2010]
|
|
|
2838 |
Added PNG_{READ,WRITE}_INT_FUNCTIONS_SUPPORTED. This allows the functions
|
|
|
2839 |
to read and write ints to be disabled independently of PNG_USE_READ_MACROS,
|
|
|
2840 |
which allows libpng to be built with the functions even though the default
|
|
|
2841 |
is to use the macros - this allows applications to choose at app build
|
|
|
2842 |
time whether or not to use macros (previously impossible because the
|
|
|
2843 |
functions weren't in the default build.)
|
|
|
2844 |
Changed Windows calling convention back to __cdecl for API functions.
|
|
|
2845 |
For Windows/x86 platforms only:
|
|
|
2846 |
__stdcall is no longer needed for Visual Basic, so libpng-1.5.0 uses
|
|
|
2847 |
__cdecl throughout (both API functions and callbacks) on Windows/x86
|
|
|
2848 |
platforms.
|
|
|
2849 |
Replaced visualc6 and visualc71 projects with new vstudio project
|
|
|
2850 |
Relaxed the overly-restrictive permissions of some files.
|
|
|
2851 |
|
|
|
2852 |
Version 1.5.0beta20 [April 24, 2010]
|
|
|
2853 |
Relaxed more overly-restrictive permissions of some files.
|
|
|
2854 |
|
|
|
2855 |
Version 1.5.0beta21 [April 27, 2010]
|
|
|
2856 |
Removed some unwanted binary bytes and changed CRLF to NEWLINE in the new
|
|
|
2857 |
vstudio project files, and some trivial editing of some files in the
|
|
|
2858 |
scripts directory.
|
|
|
2859 |
Set PNG_NO_READ_BGR, PNG_NO_IO_STATE, and PNG_NO_TIME_RFC1123 in
|
|
|
2860 |
contrib/pngminim/decoder/pngusr.h to make a smaller decoder application.
|
|
|
2861 |
|
|
|
2862 |
Version 1.5.0beta22 [April 28, 2010]
|
|
|
2863 |
Fixed dependencies of GET_INT_32 - it does not require READ_INT_FUNCTIONS
|
|
|
2864 |
because it has a macro equivalent.
|
|
|
2865 |
Improved the options.awk script; added an "everything off" option.
|
|
|
2866 |
Revised contrib/pngminim to use the "everything off" option in pngusr.dfa.
|
|
|
2867 |
|
|
|
2868 |
Version 1.5.0beta23 [April 29, 2010]
|
|
|
2869 |
Corrected PNG_REMOVED macro to take five arguments.
|
|
|
2870 |
The macro was documented with two arguments (name,ordinal), however
|
|
|
2871 |
the symbol checking .dfn files assumed five arguments. The five
|
|
|
2872 |
argument form seems more useful so it is changed to that.
|
|
|
2873 |
Corrected PNG_UNKNOWN_CHUNKS_SUPPORTED to PNG_HANDLE_AS_UNKNOWN_SUPPORTED
|
|
|
2874 |
in gregbook/readpng2.c
|
|
|
2875 |
Corrected protection of png_get_user_transform_ptr. The API declaration in
|
|
|
2876 |
png.h is removed if both READ and WRITE USER_TRANSFORM are turned off
|
|
|
2877 |
but was left defined in pngtrans.c
|
|
|
2878 |
Added logunsupported=1 to cause pnglibconf.h to document disabled options.
|
|
|
2879 |
This makes the installed pnglibconf.h more readable but causes no
|
|
|
2880 |
other change. The intention is that users of libpng will find it
|
|
|
2881 |
easier to understand if an API they need is missing.
|
|
|
2882 |
Include png_reset_zstream() in png.c only when PNG_READ_SUPPORTED is defined.
|
|
|
2883 |
Removed dummy_inflate.c from contrib/pngminim/encoder
|
|
|
2884 |
Removed contrib/pngminim/*/gather.sh; gathering is now done in the makefile.
|
|
|
2885 |
|
|
|
2886 |
Version 1.5.0beta24 [May 7, 2010]
|
|
|
2887 |
Use bitwise "&" instead of arithmetic mod in pngrutil.c calculation of the
|
|
|
2888 |
offset of the png_ptr->rowbuf pointer into png_ptr->big_row_buf.
|
|
|
2889 |
Added more blank lines for readability.
|
|
|
2890 |
|
|
|
2891 |
Version 1.5.0beta25 [June 18, 2010]
|
|
|
2892 |
In pngpread.c: png_push_have_row() add check for new_row > height
|
|
|
2893 |
Removed the now-redundant check for out-of-bounds new_row from example.c
|
|
|
2894 |
|
|
|
2895 |
Version 1.5.0beta26 [June 18, 2010]
|
|
|
2896 |
In pngpread.c: png_push_process_row() add check for too many rows.
|
|
|
2897 |
|
|
|
2898 |
Version 1.5.0beta27 [June 18, 2010]
|
|
|
2899 |
Removed the check added in beta25 as it is now redundant.
|
|
|
2900 |
|
|
|
2901 |
Version 1.5.0beta28 [June 20, 2010]
|
|
|
2902 |
Rewrote png_process_IDAT_data to consistently treat extra data as warnings
|
|
|
2903 |
and handle end conditions more cleanly.
|
|
|
2904 |
Removed the new (beta26) check in png_push_process_row().
|
|
|
2905 |
|
|
|
2906 |
Version 1.5.0beta29 [June 21, 2010]
|
|
|
2907 |
Revised scripts/options.awk to work on Sunos (but still doesn't work)
|
|
|
2908 |
Added comment to options.awk and contrib/pngminim/*/makefile to try nawk.
|
|
|
2909 |
|
|
|
2910 |
Version 1.5.0beta30 [June 22, 2010]
|
|
|
2911 |
Stop memory leak when reading a malformed sCAL chunk.
|
|
|
2912 |
|
|
|
2913 |
Version 1.5.0beta31 [June 26, 2010]
|
|
|
2914 |
Revised pngpread.c patch of beta28 to avoid an endless loop.
|
|
|
2915 |
Removed some trailing blanks.
|
|
|
2916 |
|
|
|
2917 |
Version 1.5.0beta32 [June 26, 2010]
|
|
|
2918 |
Removed leftover scripts/options.patch and scripts/options.rej
|
|
|
2919 |
|
|
|
2920 |
Version 1.5.0beta33 [July 6, 3010]
|
|
|
2921 |
Made FIXED and FLOATING options consistent in the APIs they enable and
|
|
|
2922 |
disable. Corrected scripts/options.awk to handle both command line
|
|
|
2923 |
options and options specified in the .dfa files.
|
|
|
2924 |
Changed char *msg to PNG_CONST char *msg in pngrutil.c
|
|
|
2925 |
Make png_set_sRGB_gAMA_and_cHRM set values using either the fixed or
|
|
|
2926 |
floating point APIs, but not both.
|
|
|
2927 |
Reversed patch to remove error handler when the jmp_buf is stored in the
|
|
|
2928 |
main program structure, not the png_struct.
|
|
|
2929 |
The error handler is needed because the default handler in libpng will
|
|
|
2930 |
always use the jmp_buf in the library control structure; this is never
|
|
|
2931 |
set. The gregbook code is a useful example because, even though it
|
|
|
2932 |
uses setjmp/longjmp, it shows how error handling can be implemented
|
|
|
2933 |
using control mechanisms not directly supported by libpng. The
|
|
|
2934 |
technique will work correctly with mechanisms such as Microsoft
|
|
|
2935 |
Structure Exceptions or C++ exceptions (compiler willing - note that gcc
|
|
|
2936 |
does not by default support interworking of C and C++ error handling.)
|
|
|
2937 |
Reverted changes to call png_longjmp in contrib/gregbook where it is not
|
|
|
2938 |
appropriate. If mainprog->jmpbuf is used by setjmp, then png_longjmp
|
|
|
2939 |
cannot be used.
|
|
|
2940 |
Changed "extern PNG_EXPORT" to "PNG_EXPORT" in png.h (Jan Nijtmans)
|
|
|
2941 |
Changed "extern" to "PNG_EXTERN" in pngpriv.h (except for the 'extern "C" {')
|
|
|
2942 |
|
|
|
2943 |
Version 1.5.0beta34 [July 12, 2010]
|
|
|
2944 |
Put #ifndef PNG_EXTERN, #endif around the define PNG_EXTERN in pngpriv.h
|
|
|
2945 |
|
|
|
2946 |
Version 1.5.0beta35 [July 24, 2010]
|
|
|
2947 |
Removed some newly-added TAB characters.
|
|
|
2948 |
Added -DNO_PNG_SNPRINTF to CFLAGS in scripts/makefile.dj2
|
|
|
2949 |
Moved the definition of png_snprintf() outside of the enclosing
|
|
|
2950 |
#ifdef blocks in pngconf.h
|
|
|
2951 |
|
|
|
2952 |
Version 1.5.0beta36 [July 29, 2010]
|
|
|
2953 |
Patches by John Bowler:
|
|
|
2954 |
Fixed point APIs are now supported throughout (no missing APIs).
|
|
|
2955 |
Internal fixed point arithmetic support exists for all internal floating
|
|
|
2956 |
point operations.
|
|
|
2957 |
sCAL validates the floating point strings it is passed.
|
|
|
2958 |
Safe, albeit rudimentary, Watcom support is provided by PNG_API_RULE==2
|
|
|
2959 |
Two new APIs exist to get the number of passes without turning on the
|
|
|
2960 |
PNG_INTERLACE transform and to get the number of rows in the current
|
|
|
2961 |
pass.
|
|
|
2962 |
A new test program, pngvalid.c, validates the gamma code.
|
|
|
2963 |
Errors in the 16-bit gamma correction (overflows) have been corrected.
|
|
|
2964 |
cHRM chunk testing is done consistently (previously the floating point
|
|
|
2965 |
API bypassed it, because the test really didn't work on FP, now the test
|
|
|
2966 |
is performed on the actual values to be stored in the PNG file so it
|
|
|
2967 |
works in the FP case too.)
|
|
|
2968 |
Most floating point APIs now simply call the fixed point APIs after
|
|
|
2969 |
converting the values to the fixed point form used in the PNG file.
|
|
|
2970 |
The standard headers no longer include zlib.h, which is currently only
|
|
|
2971 |
required for pngstruct.h and can therefore be internal.
|
|
|
2972 |
Revised png_get_int_32 to undo the PNG two's complement representation of
|
|
|
2973 |
negative numbers.
|
|
|
2974 |
|
|
|
2975 |
Version 1.5.0beta37 [July 30, 2010]
|
|
|
2976 |
Added a typecast in png_get_int_32() in png.h and pngrutil.h to avoid
|
|
|
2977 |
a compiler warning.
|
|
|
2978 |
Replaced oFFs 0,0 with oFFs -10,20 in pngtest.png
|
|
|
2979 |
|
|
|
2980 |
Version 1.5.0beta38 [July 31, 2010]
|
|
|
2981 |
Implemented remaining "_fixed" functions.
|
|
|
2982 |
Corrected a number of recently introduced warnings mostly resulting from
|
|
|
2983 |
safe but uncast assignments to shorter integers. Also added a zlib
|
|
|
2984 |
VStudio release library project because the latest zlib Official Windows
|
|
|
2985 |
build does not include such a thing.
|
|
|
2986 |
Revised png_get_int_16() to be similar to png_get_int_32().
|
|
|
2987 |
Restored projects/visualc71.
|
|
|
2988 |
|
|
|
2989 |
Version 1.5.0beta39 [August 2, 2010]
|
|
|
2990 |
VisualC/GCC warning fixes, VisualC build fixes
|
|
|
2991 |
The changes include support for function attributes in VC in addition to
|
|
|
2992 |
those already present in GCC - necessary because without these some
|
|
|
2993 |
warnings are unavoidable. Fixes include signed/unsigned fixes in
|
|
|
2994 |
pngvalid and checks with gcc -Wall -Wextra -Wunused.
|
|
|
2995 |
VC requires function attributes on function definitions as well as
|
|
|
2996 |
declarations, PNG_FUNCTION has been added to enable this and the
|
|
|
2997 |
relevant function definitions changed.
|
|
|
2998 |
|
|
|
2999 |
Version 1.5.0beta40 [August 6, 2010]
|
|
|
3000 |
Correct use of _WINDOWS_ in pngconf.h
|
|
|
3001 |
Removed png_mem_ #defines; they are no longer used.
|
|
|
3002 |
Added the sRGB chunk to pngtest.png
|
|
|
3003 |
|
|
|
3004 |
Version 1.5.0beta41 [August 11, 2010]
|
|
|
3005 |
Added the cHRM chunk to pngtest.png
|
|
|
3006 |
Don't try to use version-script with cygwin/mingw.
|
|
|
3007 |
Revised contrib/gregbook to work under cygwin/mingw.
|
|
|
3008 |
|
|
|
3009 |
Version 1.5.0beta42 [August 18, 2010]
|
|
|
3010 |
Add .dll.a to the list of extensions to be symlinked by Makefile.am (Yaakov)
|
|
|
3011 |
Made all API functions that have const arguments and constant string
|
|
|
3012 |
literal pointers declare them (John Bowler).
|
|
|
3013 |
|
|
|
3014 |
Version 1.5.0beta43 [August 20, 2010]
|
|
|
3015 |
Removed spurious tabs, shorten long lines (no source change)
|
|
|
3016 |
Also added scripts/chkfmt to validate the format of all the files that can
|
|
|
3017 |
reasonably be validated (it is suggested to run "make distclean" before
|
|
|
3018 |
checking, because some machine generated files have long lines.)
|
|
|
3019 |
Reformatted the CHANGES file to be more consistent throughout.
|
|
|
3020 |
Made changes to address various issues identified by GCC, mostly
|
|
|
3021 |
signed/unsigned and shortening problems on assignment but also a few
|
|
|
3022 |
difficult to optimize (for GCC) loops.
|
|
|
3023 |
Fixed non-GCC fixed point builds. In png.c a declaration was misplaced
|
|
|
3024 |
in an earlier update. Fixed to declare the auto variables at the head.
|
|
|
3025 |
Use cexcept.h in pngvalid.c.
|
|
|
3026 |
|
|
|
3027 |
Version 1.5.0beta44 [August 24, 2010]
|
|
|
3028 |
Updated CMakeLists.txt to use CMAKE_INSTALL_LIBDIR variable; useful for
|
|
|
3029 |
installing libpng in /usr/lib64 (Funda Wang).
|
|
|
3030 |
Revised CMakeLists.txt to put the man pages in share/man/man* not man/man*
|
|
|
3031 |
Revised CMakeLists.txt to make symlinks instead of copies when installing.
|
|
|
3032 |
Changed PNG_LIB_NAME from pngNN to libpngNN in CMakeLists.txt (Philip Lowman)
|
|
|
3033 |
Implemented memory checks within pngvalid
|
|
|
3034 |
Reformatted/rearranged pngvalid.c to assist use of progressive reader.
|
|
|
3035 |
Check interlaced images in pngvalid
|
|
|
3036 |
Clarified pngusr.h comments in pnglibconf.dfa
|
|
|
3037 |
Simplified the pngvalid error-handling code now that cexcept.h is in place.
|
|
|
3038 |
Implemented progressive reader in pngvalid.c for standard tests
|
|
|
3039 |
Implemented progressive read in pngvalid.c gamma tests
|
|
|
3040 |
Turn on progressive reader in pngvalid.c by default and tidy code.
|
|
|
3041 |
|
|
|
3042 |
Version 1.5.0beta45 [August 26, 2010]
|
|
|
3043 |
Added an explicit make step to projects/vstudio for pnglibconf.h
|
|
|
3044 |
Also corrected zlib.vcxproj into which Visual Studio had introduced
|
|
|
3045 |
what it calls an "authoring error". The change to make pnglibconf.h
|
|
|
3046 |
simply copies the file; in the future it may actually generate the
|
|
|
3047 |
file from scripts/pnglibconf.dfa as the other build systems do.
|
|
|
3048 |
Changed pngvalid to work when floating point APIs are disabled
|
|
|
3049 |
Renamed the prebuilt scripts/pnglibconf.h to scripts/pnglibconf.h.prebuilt
|
|
|
3050 |
Supply default values for PNG_USER_PRIVATEBUILD and PNG_USER_DLLFNAME_POSTFIX
|
|
|
3051 |
in pngpriv.h in case the user neglected to define them in their pngusr.h
|
|
|
3052 |
|
|
|
3053 |
Version 1.5.0beta46 [August 28, 2010]
|
|
|
3054 |
Added new private header files to libpng_sources in CMakeLists.txt
|
|
|
3055 |
Added PNG_READ_16BIT, PNG_WRITE_16BIT, and PNG_16BIT options.
|
|
|
3056 |
Added reference to scripts/pnglibconf.h.prebuilt in the visualc71 project.
|
|
|
3057 |
|
|
|
3058 |
Version 1.5.0beta47 [September 11, 2010]
|
|
|
3059 |
Fixed a number of problems with 64-bit compilation reported by Visual
|
|
|
3060 |
Studio 2010 (John Bowler).
|
|
|
3061 |
|
|
|
3062 |
Version 1.5.0beta48 [October 4, 2010]
|
|
|
3063 |
Updated CMakeLists.txt (Philip Lowman).
|
|
|
3064 |
Revised autogen.sh to recognize and use $AUTOCONF, $AUTOMAKE, $AUTOHEADER,
|
|
|
3065 |
$AUTOPOINT, $ACLOCAL and $LIBTOOLIZE
|
|
|
3066 |
Fixed problem with symbols creation in Makefile.am which was assuming that
|
|
|
3067 |
all versions of ccp write to standard output by default (Martin Banky). The
|
|
|
3068 |
bug was introduced in libpng-1.2.9beta5.
|
|
|
3069 |
Removed unused mkinstalldirs.
|
|
|
3070 |
|
|
|
3071 |
Version 1.5.0beta49 [October 8, 2010]
|
|
|
3072 |
Undid Makefile.am revision of 1.5.0beta48.
|
|
|
3073 |
|
|
|
3074 |
Version 1.5.0beta50 [October 14, 2010]
|
|
|
3075 |
Revised Makefile.in to account for mkinstalldirs being removed.
|
|
|
3076 |
Added some "(unsigned long)" typecasts in printf statements in pngvalid.c.
|
|
|
3077 |
Suppressed a compiler warning in png_handle_sPLT().
|
|
|
3078 |
Check for out-of-range text compression mode in png_set_text().
|
|
|
3079 |
|
|
|
3080 |
Version 1.5.0beta51 [October 15, 2010]
|
|
|
3081 |
Changed embedded dates to "(PENDING RELEASE) in beta releases (and future
|
|
|
3082 |
rc releases) to minimize the difference between releases.
|
|
|
3083 |
|
|
|
3084 |
Version 1.5.0beta52 [October 16, 2010]
|
|
|
3085 |
Restored some of the embedded dates (in png.h, png.c, documentation, etc.)
|
|
|
3086 |
|
|
|
3087 |
Version 1.5.0beta53 [October 18, 2010]
|
|
|
3088 |
Updated INSTALL to mention using "make maintainer-clean" and to remove
|
|
|
3089 |
obsolete statement about a custom ltmain.sh
|
|
|
3090 |
Disabled "color-tests" by default in Makefile.am so it will work with
|
|
|
3091 |
automake versions earlier than 1.11.1
|
|
|
3092 |
Use document name "libpng-manual.txt" instead of "libpng-<version>.txt"
|
|
|
3093 |
to simplify version differences.
|
|
|
3094 |
Removed obsolete remarks about setjmp handling from INSTALL.
|
|
|
3095 |
Revised and renamed the typedef in png.h and png.c that was designed
|
|
|
3096 |
to catch library and header mismatch.
|
|
|
3097 |
|
|
|
3098 |
Version 1.5.0beta54 [November 10, 2010]
|
|
|
3099 |
Require 48 bytes, not 64 bytes, for big_row_buf in overflow checks.
|
|
|
3100 |
Used a consistent structure for the pngget.c functions.
|
|
|
3101 |
|
|
|
3102 |
Version 1.5.0beta55 [November 21, 2010]
|
|
|
3103 |
Revised png_get_uint_32, png_get_int_32, png_get_uint_16 (Cosmin)
|
|
|
3104 |
Moved reading of file signature into png_read_sig (Cosmin)
|
|
|
3105 |
Fixed atomicity of chunk header serialization (Cosmin)
|
|
|
3106 |
Added test for io_state in pngtest.c (Cosmin)
|
|
|
3107 |
Added "#!/bin/sh" at the top of contrib/pngminim/*/gather.sh scripts.
|
|
|
3108 |
Changes to remove gcc warnings (John Bowler)
|
|
|
3109 |
Certain optional gcc warning flags resulted in warnings in libpng code.
|
|
|
3110 |
With these changes only -Wconversion and -Wcast-qual cannot be turned on.
|
|
|
3111 |
Changes are trivial rearrangements of code. -Wconversion is not possible
|
|
|
3112 |
for pngrutil.c (because of the widespread use of += et al on variables
|
|
|
3113 |
smaller than (int) or (unsigned int)) and -Wcast-qual is not possible
|
|
|
3114 |
with pngwio.c and pngwutil.c because the 'write' callback and zlib
|
|
|
3115 |
compression both fail to declare their input buffers with 'const'.
|
|
|
3116 |
|
|
|
3117 |
Version 1.5.0beta56 [December 7, 2010]
|
|
|
3118 |
Added the private PNG_UNUSED() macro definition in pngpriv.h.
|
|
|
3119 |
Added some commentary about PNG_EXPORT in png.h and pngconf.h
|
|
|
3120 |
Revised PNG_EXPORT() macro and added PNG_EXPORTA() macro, with the
|
|
|
3121 |
objective of simplifying and improving the cosmetic appearance of png.h.
|
|
|
3122 |
Fixed some incorrect "=" macro names in pnglibconf.dfa
|
|
|
3123 |
Included documentation of changes in 1.5.0 from 1.4.x in libpng-manual.txt
|
|
|
3124 |
|
|
|
3125 |
Version 1.5.0beta57 [December 9, 2010]
|
|
|
3126 |
Documented the pngvalid gamma error summary with additional comments and
|
|
|
3127 |
print statements.
|
|
|
3128 |
Improved missing symbol handling in checksym.awk; symbols missing in both
|
|
|
3129 |
the old and new files can now be optionally ignored, treated as errors
|
|
|
3130 |
or warnings.
|
|
|
3131 |
Removed references to pngvcrd.c and pnggccrd.c from the vstudio project.
|
|
|
3132 |
Updated "libpng14" to "libpng15" in the visualc71 project.
|
|
|
3133 |
Enabled the strip16 tests in pngvalid.`
|
|
|
3134 |
Don't display test results (except PASS/FAIL) when running "make test".
|
|
|
3135 |
Instead put them in pngtest-log.txt
|
|
|
3136 |
Added "--with-zprefix=<string>" to configure.ac
|
|
|
3137 |
Updated the prebuilt configuration files to autoconf version 2.68
|
|
|
3138 |
|
|
|
3139 |
Version 1.5.0beta58 [December 19, 2010]
|
|
|
3140 |
Fixed interlace image handling and add test cases (John Bowler)
|
|
|
3141 |
Fixed the clean rule in Makefile.am to remove pngtest-log.txt
|
|
|
3142 |
Made minor changes to work around warnings in gcc 3.4
|
|
|
3143 |
|
|
|
3144 |
Version 1.5.0rc01 [December 27, 2010]

|
|
|
3147 |
Version 1.5.0rc02 [December 27, 2010]
|
|
|
3148 |
Eliminated references to the scripts/*.def files in project/visualc71.
|
|
|
3149 |
|
|
|
3150 |
Version 1.5.0rc03 [December 28, 2010]
|
|
|
3151 |
Eliminated scripts/*.def and revised Makefile.am accordingly
|
|
|
3152 |
|
|
|
3153 |
Version 1.5.0rc04 [December 29, 2010]
|
|
|
3154 |
Fixed bug in background transformation handling in pngrtran.c (it was
|
|
|
3155 |
looking for the flag in png_ptr->transformations instead of in
|
|
|
3156 |
png_ptr->flags) (David Raymond).
|
|
|
3157 |
|
|
|
3158 |
Version 1.5.0rc05 [December 31, 2010]
|
|
|
3159 |
Fixed typo in a comment in CMakeLists.txt (libpng14 => libpng15) (Cosmin)
|
|
|
3160 |
|
|
|
3161 |
Version 1.5.0rc06 [January 4, 2011]
|
|
|
3162 |
Changed the new configure option "zprefix=string" to "zlib-prefix=string"
|
|
|
3163 |
|
|
|
3164 |
Version 1.5.0rc07 [January 4, 2011]

|
3170 |
version 1.5.1beta01 [January 8, 2011]
|
|
|
3171 |
Added description of png_set_crc_action() to the manual.
|
|
|
3172 |
Added a note in the manual that the type of the iCCP profile was changed
|
|
|
3173 |
from png_charpp to png_bytepp in png_get_iCCP(). This change happened
|
|
|
3174 |
in version 1.5.0beta36 but is not noted in the CHANGES. Similarly,
|
|
|
3175 |
it was changed from png_charpp to png_const_bytepp in png_set_iCCP().
|
|
|
3176 |
Ensure that png_rgb_to_gray ignores palette mapped images, if libpng
|
|
|
3177 |
internally happens to call it with one.
|
|
|
3178 |
Fixed a failure to handle palette mapped images correctly.
|
|
|
3179 |
|
|
|
3180 |
Version 1.5.1beta02 [January 14, 2011]
|
|
|
3181 |
Fixed a bug in handling of interlaced images (bero at arklinux.org).
|
|
|
3182 |
Updated CMakeLists.txt (Clifford Yapp)
|
|
|
3183 |
|
|
|
3184 |
Version 1.5.1beta03 [January 14, 2011]
|
|
|
3185 |
Fixed typecasting of some png_debug() statements (Cosmin)
|
|
|
3186 |
|
|
|
3187 |
Version 1.5.1beta04 [January 16, 2011]
|
|
|
3188 |
Updated documentation of png_set|get_tRNS() (Thomas Klausner).
|
|
|
3189 |
Mentioned in the documentation that applications must #include "zlib.h"
|
|
|
3190 |
if they need access to anything in zlib.h, and that a number of
|
|
|
3191 |
macros such as png_memset() are no longer accessible by applications.
|
|
|
3192 |
Corrected pngvalid gamma test "sample" function to access all of the color
|
|
|
3193 |
samples of each pixel, instead of sampling the red channel three times.
|
|
|
3194 |
Prefixed variable names index, div, exp, gamma with "png_" to avoid "shadow"
|
|
|
3195 |
warnings, and (mistakenly) changed png_exp() to exp().
|
|
|
3196 |
|
|
|
3197 |
Version 1.5.1beta05 [January 16, 2011]
|
|
|
3198 |
Changed variable names png_index, png_div, png_exp, and png_gamma to
|
|
|
3199 |
char_index, divisor, exp_b10, and gamma_val, respectively, and
|
|
|
3200 |
changed exp() back to png_exp().
|
|
|
3201 |
|
|
|
3202 |
Version 1.5.1beta06 [January 20, 2011]
|
|
|
3203 |
Prevent png_push_crc_skip() from hanging while reading an unknown chunk
|
|
|
3204 |
or an over-large compressed zTXt chunk with the progressive reader.
|
|
|
3205 |
Eliminated more GCC "shadow" warnings.
|
|
|
3206 |
Revised png_fixed() in png.c to avoid compiler warning about reaching the
|
|
|
3207 |
end without returning anything.
|
|
|
3208 |
|
|
|
3209 |
Version 1.5.1beta07 [January 22, 2011]
|
|
|
3210 |
In the manual, describe the png_get_IHDR() arguments in the correct order.
|
|
|
3211 |
Added const_png_structp and const_png_infop types, and used them in
|
|
|
3212 |
prototypes for most png_get_*() functions.
|
|
|
3213 |
|
|
|
3214 |
Version 1.5.1beta08 [January 23, 2011]
|
|
|
3215 |
Added png_get_io_chunk_type() and deprecated png_get_io_chunk_name()
|
|
|
3216 |
Added synopses for the IO_STATE functions and other missing synopses
|
|
|
3217 |
to the manual. Removed the synopses from libpngpf.3 because they
|
|
|
3218 |
were out of date and no longer useful. Better information can be
|
|
|
3219 |
obtained by reading the prototypes and comments in pngpriv.h
|
|
|
3220 |
Attempted to fix cpp on Solaris with S. Studio 12 cc, fix build
|
|
|
3221 |
Added a make macro DFNCPP that is a CPP that will accept the tokens in
|
|
|
3222 |
a .dfn file and adds configure stuff to test for such a CPP. ./configure
|
|
|
3223 |
should fail if one is not available.
|
|
|
3224 |
Corrected const_png_ in png.h to png_const_ to avoid polluting the namespace.
|
|
|
3225 |
Added png_get_current_row_number and png_get_current_pass_number for the
|
|
|
3226 |
benefit of the user transform callback.
|
|
|
3227 |
Added png_process_data_pause and png_process_data_skip for the benefit of
|
|
|
3228 |
progressive readers that need to stop data processing or want to optimize
|
|
|
3229 |
skipping of unread data (e.g., if the reader marks a chunk to be skipped.)
|
|
|
3230 |
|
|
|
3231 |
Version 1.5.1beta09 [January 24, 2011]
|
|
|
3232 |
Enhanced pngvalid, corrected an error in gray_to_rgb, corrected doc error.
|
|
|
3233 |
pngvalid contains tests of transforms, which tests are currently disabled
|
|
|
3234 |
because they are incompletely tested. gray_to_rgb was failing to expand
|
|
|
3235 |
the bit depth for smaller bit depth images; this seems to be a long
|
|
|
3236 |
standing error and resulted, apparently, in invalid output
|
|
|
3237 |
(CVE-2011-0408, CERT VU#643140). The documentation did not accurately
|
|
|
3238 |
describe what libpng really does when converting RGB to gray.
|
|
|
3239 |
|
|
|
3240 |
Version 1.5.1beta10 [January 27, 2010]
|
|
|
3241 |
Fixed incorrect examples of callback prototypes in the manual, that were
|
|
|
3242 |
introduced in libpng-1.0.0.
|
|
|
3243 |
In addition the order of the png_get_uint macros with respect to the
|
|
|
3244 |
relevant function definitions has been reversed. This helps the
|
|
|
3245 |
preprocessing of the symbol files be more robust. Furthermore, the
|
|
|
3246 |
symbol file preprocessing now uses -DPNG_NO_USE_READ_MACROS even when
|
|
|
3247 |
the library may actually be built with PNG_USE_READ_MACROS; this stops
|
|
|
3248 |
the read macros interfering with the symbol file format.
|
|
|
3249 |
Made the manual, synopses, and function prototypes use the function
|
|
|
3250 |
argument names file_gamma, int_file_gamma, and srgb_intent consistently.
|
|
|
3251 |
|
|
|
3252 |
Version 1.5.1beta11 [January 28, 2011]
|
|
|
3253 |
Changed PNG_UNUSED from "param=param;" to "{if(param){}}".
|
|
|
3254 |
Corrected local variable type in new API png_process_data_skip()
|
|
|
3255 |
The type was self-evidently incorrect but only causes problems on 64-bit
|
|
|
3256 |
architectures.
|
|
|
3257 |
Added transform tests to pngvalid and simplified the arguments.
|
|
|
3258 |
|
|
|
3259 |
Version 1.5.1rc01 [January 29, 2011]
|
|
|
3260 |
No changes.
|
|
|
3261 |
|
|
|
3262 |
Version 1.5.1rc02 [January 31, 2011]
|
|
|
3263 |
Added a request in the manual that applications do not use "png_" or
|
|
|
3264 |
"PNG_" to begin any of their own symbols.
|
|
|
3265 |
Changed PNG_UNUSED to "(void)param;" and updated the commentary in pngpriv.h
|
|
|
3266 |
|
|
|
3267 |
Version 1.5.1 [February 3, 2011]
|
|
|
3268 |
No changes.
|
|
|
3269 |
|
|
|
3270 |
Version 1.5.2beta01 [February 13, 2011]
|
|
|
3271 |
More -Wshadow fixes for older gcc compilers. Older gcc versions apparently
|
|
|
3272 |
check formal parameters names in function declarations (as well as
|
|
|
3273 |
definitions) to see if they match a name in the global namespace.
|
|
|
3274 |
Revised PNG_EXPORTA macro to not use an empty parameter, to accommodate the
|
|
|
3275 |
old VisualC++ preprocessor.
|
|
|
3276 |
Turned on interlace handling in png_read_png().
|
|
|
3277 |
Fixed gcc pendantic warnings.
|
|
|
3278 |
Handle longjmp in Cygwin.
|
|
|
3279 |
Fixed png_get_current_row_number() in the interlaced case.
|
|
|
3280 |
Cleaned up ALPHA flags and transformations.
|
|
|
3281 |
Implemented expansion to 16 bits.
|
|
|
3282 |
|
|
|
3283 |
Version 1.5.2beta02 [February 19, 2011]
|
|
|
3284 |
Fixed mistake in the descriptions of user read_transform and write_transform
|
|
|
3285 |
function prototypes in the manual. The row_info struct is png_row_infop.
|
|
|
3286 |
Reverted png_get_current_row_number() to previous (1.5.2beta01) behavior.
|
|
|
3287 |
Corrected png_get_current_row_number documentation
|
|
|
3288 |
Fixed the read/write row callback documentation.
|
|
|
3289 |
This documents the current behavior, where the callback is called after
|
|
|
3290 |
every row with information pertaining to the next row.
|
|
|
3291 |
|
|
|
3292 |
Version 1.5.2beta03 [March 3, 2011]
|
|
|
3293 |
Fixed scripts/makefile.vcwin32
|
|
|
3294 |
Updated contrib/pngsuite/README to add the word "modify".
|
|
|
3295 |
Define PNG_ALLOCATED to blank when _MSC_VER<1300.
|
|
|
3296 |
|
|
|
3297 |
Version 1.5.2rc01 [March 19, 2011]
|
|
|
3298 |
Define remaining attributes to blank when MSC_VER<1300.
|
|
|
3299 |
ifdef out mask arrays in pngread.c when interlacing is not supported.
|
|
|
3300 |
|
|
|
3301 |
Version 1.5.2rc02 [March 22, 2011]
|
|
|
3302 |
Added a hint to try CPP=/bin/cpp if "cpp -E" fails in scripts/pnglibconf.mak
|
|
|
3303 |
and in contrib/pngminim/*/makefile, eg., on SunOS 5.10, and removed "strip"
|
|
|
3304 |
from the makefiles.
|
|
|
3305 |
Fixed a bug (present since libpng-1.0.7) that makes png_handle_sPLT() fail
|
|
|
3306 |
to compile when PNG_NO_POINTER_INDEXING is defined (Chubanov Kirill)
|
|
|
3307 |
|
|
|
3308 |
Version 1.5.2rc03 [March 24, 2011]
|
|
|
3309 |
Don't include standard header files in png.h while building the symbol table,
|
|
|
3310 |
to avoid cpp failure on SunOS (introduced PNG_BUILDING_SYMBOL_TABLE macro).
|
|
|
3311 |
|
|
|
3312 |
Version 1.5.2 [March 31, 2011]
|
|
|
3313 |
No changes.
|
|
|
3314 |
|
|
|
3315 |
Version 1.5.3beta01 [April 1, 2011]
|
|
|
3316 |
Re-initialize the zlib compressor before compressing non-IDAT chunks.
|
|
|
3317 |
Added API functions to set parameters for zlib compression of non-IDAT
|
|
|
3318 |
chunks.
|
|
|
3319 |
|
|
|
3320 |
Version 1.5.3beta02 [April 3, 2011]
|
|
|
3321 |
Updated scripts/symbols.def with new API functions.
|
|
|
3322 |
Only compile the new zlib re-initializing code when text or iCCP is
|
|
|
3323 |
supported, using PNG_WRITE_COMPRESSED_TEXT_SUPPORTED macro.
|
|
|
3324 |
Improved the optimization of the zlib CMF byte (see libpng-1.2.6beta03).
|
|
|
3325 |
Optimize the zlib CMF byte in non-IDAT compressed chunks
|
|
|
3326 |
|
|
|
3327 |
Version 1.5.3beta03 [April 16, 2011]
|
|
|
3328 |
Fixed gcc -ansi -pedantic compile. A strict ANSI system does not have
|
|
|
3329 |
snprintf, and the "__STRICT_ANSI__" detects that condition more reliably
|
|
|
3330 |
than __STDC__ (John Bowler).
|
|
|
3331 |
Removed the PNG_PTR_NORETURN attribute because it too dangerous. It tells
|
|
|
3332 |
the compiler that a user supplied callback (the error handler) does not
|
|
|
3333 |
return, yet there is no guarantee in practice that the application code
|
|
|
3334 |
will correctly implement the error handler because the compiler only
|
|
|
3335 |
issues a warning if there is a mistake (John Bowler).
|
|
|
3336 |
Removed the no-longer-used PNG_DEPSTRUCT macro.
|
|
|
3337 |
Updated the zlib version to 1.2.5 in the VStudio project.
|
|
|
3338 |
Fixed 64-bit builds where png_uint_32 is smaller than png_size_t in
|
|
|
3339 |
pngwutil.c (John Bowler).
|
|
|
3340 |
Fixed bug with stripping the filler or alpha channel when writing, that
|
|
|
3341 |
was introduced in libpng-1.5.2beta01 (bug report by Andrew Church).
|
|
|
3342 |
|
|
|
3343 |
Version 1.5.3beta04 [April 27, 2011]
|
|
|
3344 |
Updated pngtest.png with the new zlib CMF optimization.
|
|
|
3345 |
Cleaned up conditional compilation code and of background/gamma handling
|
|
|
3346 |
Internal changes only except a new option to avoid compiling the
|
|
|
3347 |
png_build_grayscale_palette API (which is not used at all internally.)
|
|
|
3348 |
The main change is to move the transform tests (READ_TRANSFORMS,
|
|
|
3349 |
WRITE_TRANSFORMS) up one level to the caller of the APIs. This avoids
|
|
|
3350 |
calls to spurious functions if all transforms are disabled and slightly
|
|
|
3351 |
simplifies those functions. Pngvalid modified to handle this.
|
|
|
3352 |
A minor change is to stop the strip_16 and expand_16 interfaces from
|
|
|
3353 |
disabling each other; this allows the future alpha premultiplication
|
|
|
3354 |
code to use 16-bit intermediate values while still producing 8-bit output.
|
|
|
3355 |
png_do_background and png_do_gamma have been simplified to take a single
|
|
|
3356 |
pointer to the png_struct rather than pointers to every item required
|
|
|
3357 |
from the png_struct. This makes no practical difference to the internal
|
|
|
3358 |
code.
|
|
|
3359 |
A serious bug in the pngvalid internal routine 'standard_display_init' has
|
|
|
3360 |
been fixed - this failed to initialize the red channel and accidentally
|
|
|
3361 |
initialized the alpha channel twice.
|
|
|
3362 |
Changed png_struct jmp_buf member name from png_jmpbuf to tmp_jmpbuf to
|
|
|
3363 |
avoid a possible clash with the png_jmpbuf macro on some platforms.
|
|
|
3364 |
|
|
|
3365 |
Version 1.5.3beta05 [May 6, 2011]
|
|
|
3366 |
Added the "_POSIX_SOURCE" feature test macro to ensure libpng sees the
|
|
|
3367 |
correct API. _POSIX_SOURCE is defined in pngpriv.h, pngtest.c and
|
|
|
3368 |
pngvalid.c to ensure that POSIX conformant systems disable non-POSIX APIs.
|
|
|
3369 |
Removed png_snprintf and added formatted warning messages. This change adds
|
|
|
3370 |
internal APIs to allow png_warning messages to have parameters without
|
|
|
3371 |
requiring the host OS to implement snprintf. As a side effect the
|
|
|
3372 |
dependency of the tIME-supporting RFC1132 code on stdio is removed and
|
|
|
3373 |
PNG_NO_WARNINGS does actually work now.
|
|
|
3374 |
Pass "" instead of '\0' to png_default_error() in png_err(). This mistake
|
|
|
3375 |
was introduced in libpng-1.2.20beta01.
|
|
|
3376 |
Added PNG_WRITE_OPTIMIZE_CMF_SUPPORTED macro to make the zlib "CMF" byte
|
|
|
3377 |
optimization configureable.
|
|
|
3378 |
IDAT compression failed if preceded by a compressed text chunk (bug
|
|
|
3379 |
introduced in libpng-1.5.3beta01-02). This was because the attempt to
|
|
|
3380 |
reset the zlib stream in png_write_IDAT happened after the first IDAT
|
|
|
3381 |
chunk had been deflated - much too late. In this change internal
|
|
|
3382 |
functions were added to claim/release the z_stream and, hopefully, make
|
|
|
3383 |
the code more robust. Also deflateEnd checking is added - previously
|
|
|
3384 |
libpng would ignore an error at the end of the stream.
|
|
|
3385 |
|
|
|
3386 |
Version 1.5.3beta06 [May 8, 2011]
|
|
|
3387 |
Removed the -D_ALL_SOURCE from definitions for AIX in CMakeLists.txt
|
|
|
3388 |
Implemented premultiplied alpha support: png_set_alpha_mode API
|
|
|
3389 |
|
|
|
3390 |
Version 1.5.3beta07 [May 11, 2011]
|
|
|
3391 |
Added expand_16 support to the high level interface.
|
|
|
3392 |
Added named value and 'flag' gamma support to png_set_gamma. Made a minor
|
|
|
3393 |
change from the previous (unreleased) ABI/API to hide the exact value used
|
|
|
3394 |
for Macs - it's not a good idea to embed this in the ABI!
|
|
|
3395 |
Moved macro definitions for PNG_HAVE_IHDR, PNG_HAVE_PLTE, and PNG_AFTER_IDAT
|
|
|
3396 |
from pngpriv.h to png.h because they must be visible to applications
|
|
|
3397 |
that call png_set_unknown_chunks().
|
|
|
3398 |
Check for up->location !PNG_AFTER_IDAT when writing unknown chunks
|
|
|
3399 |
before IDAT.
|
|
|
3400 |
|
|
|
3401 |
Version 1.5.3beta08 [May 16, 2011]
|
|
|
3402 |
Improved "pngvalid --speed" to exclude more of pngvalid from the time.
|
|
|
3403 |
Documented png_set_alpha_mode(), other changes in libpng.3/libpng-manual.txt
|
|
|
3404 |
The cHRM chunk now sets the defaults for png_set_rgb_to_gray() (when negative
|
|
|
3405 |
parameters are supplied by the caller), while in the absence of cHRM
|
|
|
3406 |
sRGB/Rec 709 values are still used.
|
|
|
3407 |
The bKGD chunk no longer overwrites the background value set by
|
|
|
3408 |
png_set_background(), allowing the latter to be used before the file
|
|
|
3409 |
header is read. It never performed any useful function to override
|
|
|
3410 |
the default anyway.
|
|
|
3411 |
Added memory overwrite and palette image checks to pngvalid.c
|
|
|
3412 |
Previously palette image code was poorly checked. Since the transformation
|
|
|
3413 |
code has a special palette path in most cases this was a severe weakness.
|
|
|
3414 |
Minor cleanup and some extra checking in pngrutil.c and pngrtran.c. When
|
|
|
3415 |
expanding an indexed image, always expand to RGBA if transparency is
|
|
|
3416 |
present.
|
|
|
3417 |
|
|
|
3418 |
Version 1.5.3beta09 [May 17, 2011]
|
|
|
3419 |
Reversed earlier 1.5.3 change of transformation order; move png_expand_16
|
|
|
3420 |
back where it was. The change doesn't work because it requires 16-bit
|
|
|
3421 |
gamma tables when the code only generates 8-bit ones. This fails
|
|
|
3422 |
silently; the libpng code just doesn't do any gamma correction. Moving
|
|
|
3423 |
the tests back leaves the old, inaccurate, 8-bit gamma calculations, but
|
|
|
3424 |
these are clearly better than none!
|
|
|
3425 |
|
|
|
3426 |
Version 1.5.3beta10 [May 20, 2011]
|
|
|
3427 |
|
|
|
3428 |
png_set_background() and png_expand_16() did not work together correctly.
|
|
|

This problem is present in 1.5.2; if png_set_background is called with
|
|
|
3430 |
need_expand false and the matching 16 bit color libpng erroneously just
|
|
|
3431 |
treats it as an 8-bit color because of where png_do_expand_16 is in the
|
|
|
3432 |
transform list. This simple fix reduces the supplied colour to 8-bits,
|
|
|
3433 |
so it gets smashed, but this is better than the current behavior.
|
|
|
3434 |
Added tests for expand16, more fixes for palette image tests to pngvalid.
|
|
|
3435 |
Corrects the code for palette image tests and disables attempts to
|
|
|
3436 |
validate palette colors.

Version 1.5.3rc01 [June 3, 2011]
|
|
|
3439 |
No changes.
|
|
|
3440 |
|
|
|
3441 |
Version 1.5.3rc02 [June 8, 2011]
|
|
|
3442 |
Fixed uninitialized memory read in png_format_buffer() (Bug report by
|
|
|
3443 |
Frank Busse, CVE-2011-2501, related to CVE-2004-0421).
|
|
|
3444 |
|
|
|
3445 |
Version 1.5.3beta11 [June 11, 2011]
|
|
|
3446 |
Fixed png_handle_sCAL which is broken in 1.5; added sCAL to pngtest.png
|
|
|
3447 |
Revised documentation about png_set_user_limits() to say that it also affects
|
|
|
3448 |
png writing.
|
|
|
3449 |
Revised handling of png_set_user_limits() so that it can increase the
|
|
|
3450 |
limit beyond the PNG_USER_WIDTH|HEIGHT_MAX; previously it could only
|
|
|
3451 |
reduce it.
|
|
|
3452 |
Make the 16-to-8 scaling accurate. Dividing by 256 with no rounding is
|
|
|
3453 |
wrong (high by one) 25% of the time. Dividing by 257 with rounding is
|
|
|
3454 |
wrong in 128 out of 65536 cases. Getting the right answer all the time
|
|
|
3455 |
without division is easy.
|
|
|
3456 |
Added "_SUPPORTED" to the PNG_WRITE_CUSTOMIZE_ZTXT_COMPRESSION macro.
|
|
|
3457 |
Added projects/owatcom, an IDE project for OpenWatcom to replace
|
|
|
3458 |
scripts/makefile.watcom. This project works with OpenWatcom 1.9. The
|
|
|
3459 |
IDE autogenerates appropriate makefiles (libpng.mk) for batch processing.
|
|
|
3460 |
The project is configurable, unlike the Visual Studio project, so long
|
|
|
3461 |
as the developer has an awk.
|
|
|
3462 |
Changed png_set_gAMA to limit the gamma value range so that the inverse
|
|
|
3463 |
of the stored value cannot overflow the fixed point representation,
|
|
|
3464 |
and changed other things OpenWatcom warns about.
|
|
|
3465 |
Revised pngvalid.c to test PNG_ALPHA_MODE_SUPPORTED correctly. This allows
|
|
|
3466 |
pngvalid to build when ALPHA_MODE is not supported, which is required if
|
|
|
3467 |
it is to build on libpng 1.4.
|
|
|
3468 |
Removed string/memory macros that are no longer used and are not
|
|
|
3469 |
necessarily fully supportable, particularly png_strncpy and png_snprintf.
|
|
|
3470 |
Added log option to pngvalid.c and attempted to improve gamma messages.
|
|
|
3471 |
|
|
|
3472 |
Version 1.5.3 [omitted]
|
|
|
3473 |
People found the presence of a beta release following an rc release
|
|
|
3474 |
to be confusing; therefore we bump the version to libpng-1.5.4beta01
|
|
|
3475 |
and there will be no libpng-1.5.3 release.
|
|
|
3476 |
|
|
|
3477 |
Version 1.5.4beta01 [June 14, 2011]
|
|
|
3478 |
Made it possible to undefine PNG_READ_16_TO_8_ACCURATE_SCALE_SUPPORTED
|
|
|
3479 |
to get the same (inaccurate) output as libpng-1.5.2 and earlier.
|
|
|
3480 |
Moved definitions of PNG_HAVE_IHDR, PNG_AFTER_IDAT, and PNG_HAVE_PLTE
|
|
|
3481 |
outside of an unknown-chunk block in png.h because they are also
|
|
|
3482 |
needed for other uses.
|
|
|
3483 |
|
|
|
3484 |
Version 1.5.4beta02 [June 14, 2011]
|
|
|
3485 |
Fixed and clarified LEGACY 16-to-8 scaling code.
|
|
|
3486 |
Added png_set_chop_16() API, to match inaccurate results from previous
|
|
|
3487 |
libpng versions.
|
|
|
3488 |
Removed the ACCURATE and LEGACY options (they are no longer useable)
|
|
|
3489 |
Use the old scaling method for background if png_set_chop_16() was
|
|
|
3490 |
called.
|
|
|
3491 |
Made png_set_chop_16() API removeable by disabling PNG_CHOP_16_TO_8_SUPPORTED
|
|
|
3492 |
|
|
|
3493 |
Version 1.5.4beta03 [June 15, 2011]
|
|
|
3494 |
Fixed a problem in png_do_expand_palette() exposed by optimization in
|
|
|
3495 |
1.5.3beta06
|
|
|
3496 |
Also removed a spurious and confusing "trans" member ("trans") from png_info.
|
|
|
3497 |
The palette expand optimization prevented expansion to an intermediate RGBA
|
|
|
3498 |
form if tRNS was present but alpha was marked to be stripped; this exposed
|
|
|
3499 |
a check for tRNS in png_do_expand_palette() which is inconsistent with the
|
|
|
3500 |
code elsewhere in libpng.
|
|
|
3501 |
Correction to the expand_16 code; removed extra instance of
|
|
|
3502 |
png_set_scale_16_to_8 from pngpriv.h
|
|
|
3503 |
|
|
|
3504 |
Version 1.5.4beta04 [June 16, 2011]
|
|
|
3505 |
Added a missing "#ifdef PNG_READ_BACKGROUND_SUPPORTED/#endif" in pngrtran.c
|
|
|
3506 |
Added PNG_TRANSFORM_CHOP_16 to the high-level read transforms.
|
|
|
3507 |
Made PNG_READ_16_TO_8_ACCURATE_SCALE configurable again. If this is
|
|
|
3508 |
not enabled, png_set_strip_16() and png_do_scale_16_to_8() aren't built.
|
|
|
3509 |
Revised contrib/visupng, gregbook, and pngminim to demonstrate chop_16_to_8
|
|
|
3510 |
|
|
|
3511 |
Version 1.5.4beta05 [June 16, 2011]
|
|
|
3512 |
Renamed png_set_strip_16() to png_set_scale_16() and renamed
|
|
|
3513 |
png_set_chop_16() to png_set_strip(16) in an attempt to minimize the
|
|
|
3514 |
behavior changes between libpng14 and libpng15.
|
|
|
3515 |
|
|
|
3516 |
Version 1.5.4beta06 [June 18, 2011]
|
|
|
3517 |
Fixed new bug that was causing both strip_16 and scale_16 to be applied.
|
|
|
3518 |
|
|
|
3519 |
Version 1.5.4beta07 [June 19, 2011]
|
|
|
3520 |
Fixed pngvalid, simplified macros, added checking for 0 in sCAL.
|
|
|
3521 |
The ACCURATE scale macro is no longer defined in 1.5 - call the
|
|
|
3522 |
png_scale_16_to_8 API. Made sure that PNG_READ_16_TO_8 is still defined
|
|
|
3523 |
if the png_strip_16_to_8 API is present. png_check_fp_number now
|
|
|
3524 |
maintains some state so that positive, negative and zero values are
|
|
|
3525 |
identified. sCAL uses these to be strictly spec conformant.
|
|
|
3526 |
|
|
|
3527 |
Version 1.5.4beta08 [June 23, 2011]
|
|
|
3528 |
Fixed pngvalid if ACCURATE_SCALE is defined.
|
|
|
3529 |
Updated scripts/pnglibconf.h.prebuilt.
|
|
|
3530 |
|
|
|
3531 |
Version 1.5.4rc01 [June 30, 2011]
|
|
|
3532 |
Define PNG_ALLOCATED to "restrict" only if MSC_VER >= 1400.
|
|
|
3533 |
|
|
|
3534 |
Version 1.5.4 [July 7, 2011]
