Package com.twelvemonkeys.imageio.stream

Class DirectImageInputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.io.DataInput, java.lang.AutoCloseable, javax.imageio.stream.ImageInputStream
    public final class DirectImageInputStream
extends javax.imageio.stream.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.
