Re: 24-bit color support to Xvnc

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


Ok James,

I have removed pixelformat at all and using "vncserver -depth 8", "vncserver
-depth 16" and "vncserver -depth 24" created three sessions. For depth 8 and
16, Xvnc info dialog box showing correct info but for depth 24 it is showing
default 24 depth but pixel format 16. :-(

Please refer the attached xwininfo dialog box for all three sessions.

Is it related to RGB565. because i could see that when i specified depth 16,
it uses RGB565 and same it is uses for depth 24 even though default server
depth is 24 BGR888.

Thanks,
Paresh
