Package com.twelvemonkeys.imageio.stream

Class 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.
