Re: 24-bit color support to Xvnc

James,

I think you are missing something here. Google tells me (
http://en.wikipedia.org/wiki/Alpha_channel) that Microsoft makes use of this
upper 8 bits. however, I found that X11 only uses these bits as part of
XRender and  RealVNC doesn't seem to support XRender. Am i correct?

Thanks,
Paresh
