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.
