Class ASCII85InputStream

java.lang.Object
  java.io.InputStream
      org.freehep.util.io.ASCII85InputStream

All Implemented Interfaces:

Closeable, ASCII85

public class ASCII85InputStream
extends InputStream
implements ASCII85

The ASCII85InputStream decodes ASCII base-85 encoded data. The exact definition of ASCII base-85 encoding can be found in the PostScript Language Reference (3rd ed.) chapter 3.13.3. IMPORTANT: inherits from InputStream rather than FilterInputStream so that the correct read(byte[], int, int) method is used.
