Re: 24-bit color support to Xvnc

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Thanks for reply. I am using pixel format RGB888 while calling Xvnc. Please
refer the command given below:

Xvnc :10 -desktop 'UNIX" -httpd /usr/local/vnc/classes -auth /.Xauthority
-geometry 1268x896 -depth 24 -pixelformat RGB888 -rfbwait 30000 -rfbauth
/passwd -pn -fp

Then also i am getting pixel format 16 depth and it is BGR565. Please refer
the attached file. Could you tell me why it is happening like this, What
should i do if i want to use 24 bit color depth?

Thanks,

Paresh
