All Implemented Interfaces:

Closeable, DataInput, AutoCloseable, ImageInputStream

public final class DirectImageInputStream
extends ImageInputStreamImpl

An ImageInputStream that adapts an InputSteam, by reading directly from the stream without and form of caching or buffering.

Note: This is not a general-purpose ImageInputStream, and is designed for reading large chunks, typically of pixel data, from an InputStream. It does not support backwards seeking, or reading bits.
