[LibVNCServer](http://sourceforge.net/projects/libvncserver/) is
|
||
|
|
a library for easy implementation of a RDP/VNC server.

The [Tight PNG encoding](http://wiki.qemu.org/VNC_Tight_PNG) 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](http://github.com/kanaka/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).
