Package javax.imageio.stream

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.
