Class RRE
java.lang.Object
gnu.rfb.Rect
gnu.rfb.RRE
- All Implemented Interfaces:
- java.lang.Cloneable
- Direct Known Subclasses:
- CoRRE
public class RRE
- extends Rect
Provides encoding and decoding of images using the RRE encoding.
RRE - Rise-and-Run-length Encoding.
We have an RRE header structure giving the number of subrectangles following.
Finally the data follows in the form [...]
where each is [].
