I have a X software which only runs at 640x480. Now I have a Xvnc with XDMCP that runs on 320x240, and this result the software being "cropped" so only a 1/4th of the software is visible. Now I would want to "scale" the software by 50 % by some wrapper. How can this be achieved?
In other words, any software run through the wrapper should be shrinked or enlarged according to a option.
If speed is a problem, maybe you could solve your problem with NX. It's highly optimized to work over slow networks with high latency. I've successfully used it with a 1024x768 desktop over an ISDN line.
Edit:
If NX does't work, maybe you can speed things up with the help of RDP, which is also much more efficient than VNC. I haven't tested this, though.
