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.

Interface Summary
Interface	Description
ImageInputStream	A seekable input stream interface for use by `ImageReader`s.
ImageOutputStream	A seekable output stream interface for use by `ImageWriter`s.

Class Summary
Class	Description
FileCacheImageInputStream	An implementation of `ImageInputStream` that gets its input from a regular `InputStream`.
FileCacheImageOutputStream	An implementation of `ImageOutputStream` that writes its output to a regular `OutputStream`.
FileImageInputStream	An implementation of `ImageInputStream` that gets its input from a `File` or `RandomAccessFile`.
FileImageOutputStream	An implementation of `ImageOutputStream` that writes its output directly to a `File` or `RandomAccessFile`.
IIOByteBuffer	A class representing a mutable reference to an array of bytes and an offset and length within that array.
ImageInputStreamImpl	An abstract class implementing the `ImageInputStream` interface.
ImageOutputStreamImpl	An abstract class implementing the `ImageOutputStream` interface.
MemoryCacheImageInputStream	An implementation of `ImageInputStream` that gets its input from a regular `InputStream`.
MemoryCacheImageOutputStream	An implementation of `ImageOutputStream` that writes its output to a regular `OutputStream`.
