LibVNCServer is a library for easy implementation of a RDP/VNC server.

Tight PNG

Copyright (C) 2010 Joel Martin

The Tight PNG encoding is similar to the Tight encoding, but the basic compression (zlib) is replaced with PNG data.

This encoding allows for simple, fast clients and bandwidth efficient clients:

• The PNG data can be rendered directly by the client so there is negligible decode work needed in the VNC client itself.
• PNG images are zlib compressed internally (along with other optimizations) so tightPng is comparable in bandwith to tight.
• PNG images are natively supported in the browsers. This is optimal for web based VNC clients such as noVNC

Usage

See INSTALL for build instructions. To build with the tightPng encoding, you must also have libpng development libraries install. For example:

sudo apt-get install libpng-dev

TODO

• Handle palette mode (non-truecolor).
