Class ASCII85InputStream

java.lang.Object

java.io.InputStream

org.apache.xmlgraphics.util.io.ASCII85InputStream

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable, ASCII85Constants

public class ASCII85InputStream
extends java.io.InputStream
implements ASCII85Constants

This class applies a ASCII85 decoding to the stream.

The class is derived from InputStream instead of FilteredInputStream because we can use the read(byte[], int, int) method from InputStream which simply delegates to read(). This makes the implementation easier.

The filter is described in chapter 3.13.3 of the PostScript Language Reference (third edition).
