All Implemented Interfaces:

Closeable

public class ASCIIHexInputStream
extends InputStream

The ASCIIHexOutputStream decodes ASCII Hexadecimal. The exact definition of ASCII Hex 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.
