vncviewer ignores -LowColourLevel switch
Last modified: 2013-04-30 19:43:44 EDT
Description of problem:
vncviewer ignores the -LowColourLevel switch and uses a 24 bit full colour connection.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Run "vncviewer -LowColourLevel 2 <host>".
2. Note that the output says "Using pixel format depth 24 (32bpp) little-endian rgb888".
3. Note that the view takes ages to redraw if the host is on a slow link.
A full colour connection is used.
The requested connection type is used.
It seems that the old realvnc client in previous releases had the same problem - the only difference was that it defaulted to an 8bpp connection instead of a 32bpp connection.
After discussion in upstream this is actually not a bug but a feature. When you would like to use reduced color level you have to specify also -AutoSelect=0 parameter.
Main reason is that some users would like to use auto select mode and would like to control which reduced color level is used when autoselecting code decides to switch to reduced color level.
Currently there is another bug in code - you have to use -FullColor=0 in addition to -AutoSelect=0 parameter to get -LowColorLevel working as you wish. This will be fixed in the next release.
