Class BufferedImageInputStream

java.lang.Object

javax.imageio.stream.ImageInputStreamImpl

com.twelvemonkeys.imageio.stream.BufferedImageInputStream

All Implemented Interfaces:

java.io.Closeable, java.io.DataInput, java.lang.AutoCloseable, javax.imageio.stream.ImageInputStream

public final class BufferedImageInputStream
extends javax.imageio.stream.ImageInputStreamImpl
implements javax.imageio.stream.ImageInputStream

A buffered ImageInputStream. Experimental - seems to be effective for FileImageInputStream and FileCacheImageInputStream when doing a lot of single-byte reads (or short byte-array reads) on OS X at least. Code that uses the readFully methods are not affected by the issue.
