857 |
* for the various surface types to manipulate pixels and pixel data.
|
|
|
858 |
* The surface-specific macros are typically supplied by header files
|
|
|
859 |
* named after the SurfaceType name (eg. IntArgb.h, ByteGray.h, etc.).
|
|
|
860 |
*
|
|
|
861 |
* In the macro names in the following definitions, the string <stype>
|
|
|
862 |
* is used as a place holder for the SurfaceType name (eg. IntArgb). The
|
|
|
863 |
* string <strategy> is a place holder for the strategy name (eg. 4ByteArgb).
|
|
|
864 |
* The macros above access these type specific macros using the ANSI
|
|
|
865 |
* CPP token concatenation operator "##".
|
|
|
866 |
*
|
|
|
867 |
* Declare<stype>AlphaLoadData Declare the variables used when an alpha

* not blending needs to occur

872 |
* into a variable used later (the strategy

873 |
* type determines the bit depth of the

876 |
* surface type into the form required by

877 |
* the given strategy. Typically there will
|
|
