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.
