A package of the Java Image I/O API dealing with low-level I/O from
|
|
|
34 |
files and streams.
|
|
|
35 |
|
|
|
36 |
<p>
|
|
|
37 |
|
|
|
38 |
The <code>ImageInputStream</code> interface unifies streaming and
|
|
|
39 |
file-based operations. An abstract base class,
|
|
|
40 |
<code>ImageInputStreamImpl</code> is provided to simplify writing
|
|
|
41 |
a new <code>ImageInputStream</code> class. Concrete implementation
|
|
|
42 |
classes (<code>FileImageInputStream</code>,
|
|
|
43 |
<code>FileCacheImageInputStream</code>, and
|
|
|
44 |
<code>MemoryCacheImageInputStream</code>) are provided that allow
|
|
|
45 |
input to come from a <code>File</code> or <code>InputStream</code>
|
|
|
46 |
with or without the use of a temporary cache file.
|
|
|
47 |
|
|
|
48 |
<p>
|
|
|
49 |
|
|
|
50 |
The <code>ImageOutputStream</code> interface performs an analogous
|
|
|
51 |
function for output. An abstract base class,
|
|
|
52 |
<code>ImageOutputStreamImpl</code> is provided, along with
|
|
|
53 |
concrete implementation classes (<code>FileImageOutputStream</code>,
|
|
|
54 |
<code>FileCacheImageOutputStream</code>, and
|
|
|
55 |
<code>MemoryCacheImageOutputStream</code>) are provided that allow
|
|
|
56 |
output to go to a <code>File</code> or <code>OutputStream</code> with
|
|
|
57 |
or without the use of a temporary cache file.
|
|
|
58 |
|
|
|
59 |
<p>
|
|
|
60 |
|
|
|
61 |
The <code>IIOByteBuffer</code> class provides an alternative way to
|
|
|
62 |
perform reads of sequences of bytes that reduces the amount of
|
|
|
63 |
internal data copying.
