VNC client expectations

[Dave Hudson]

Hi,

I'm currently writing a VNC server for an 8-bit processor (Ubicom 
IP2022) and have been wondering about how best to handle translation of 
the internal framebuffer representation that I'm using to whatever the 
VNC clients want to use.

So far I've found that WinVNC is very forgiving and will accept things 
with almost no translation at all, but my Linux client seems to expect 
things in 24-bit form.  This isn't particularly a problem as I can 
translate things to 24-bit form really efficiently but I wondered if any 
clients might ever wish to negotiate to use more than 24 bits?  Does 
anyone know of any clients that might attempt to do this?

The other thing I've noticed is that WinVNC seems to want to try to 
negotiate v3.5 of RFB while the Linux client asks for v3.3.  I have the 
3.3 protocol spec - is there a 3.5 spec anywhere or is this just 
encapsulated in the source code?


Thanks,
Dave
