A package of the Java Image I/O API dealing with low-level I/O from
files and streams.
The ImageInputStream
interface unifies streaming and
file-based operations. An abstract base class,
ImageInputStreamImpl
is provided to simplify writing
a new ImageInputStream
class. Concrete implementation
classes (FileImageInputStream
,
FileCacheImageInputStream
, and
MemoryCacheImageInputStream
) are provided that allow
input to come from a File
or InputStream
with or without the use of a temporary cache file.
The ImageOutputStream
interface performs an analogous
function for output. An abstract base class,
ImageOutputStreamImpl
is provided, along with
concrete implementation classes (FileImageOutputStream
,
FileCacheImageOutputStream
, and
MemoryCacheImageOutputStream
) are provided that allow
output to go to a File
or OutputStream
with
or without the use of a temporary cache file.
The IIOByteBuffer
class provides an alternative way to
perform reads of sequences of bytes that reduces the amount of
internal data copying.
