com.twelvemonkeys.imageio.stream.SubImageOutputStream

All Implemented Interfaces:

Closeable, DataInput, DataOutput, AutoCloseable, ImageInputStream, ImageOutputStream

public final class SubImageOutputStream
extends ImageOutputStreamImpl

ImageOutputStream that writes through a delegate, but keeps local position and bit offset. Note: Flushing or closing this stream will *not* have an effect on the delegate.
