(Obviously, it would be much more >computationally efficient to encode from the high level calls, rather than >diff-ing bitmaps.) Computationally yes, but from a design point of view, no. In fact, to be as simple and cross-platform as possible, VNC does in fact work on raw framebuffers, and uses compression techniques on that. Read the RFB protocol spec (in the Documentation section of the AT&T website) and you'll see what I mean. -- -------------------------------------------------------------- from: Jonathan "Chromatix" Morton mail: [EMAIL PROTECTED] (not for attachments) website: http://www.chromatix.uklinux.net/vnc/ geekcode: GCS$/E dpu(!) s:- a20 C+++ UL++ P L+++ E W+ N- o?
