If I recall correctly, only the starting addresses must be DWORD aligned. Also, isn't there byte enable bits in the risc commands that could be used for the bitmapped clipping? It's been a while now :) My original code used the WRITEC instruction in the clipping code. On the subject of FIFOs, etc., in the planar modes the FIFOs have to be balanced well to avoid dropping bytes. The code in the bt848.vxd for Windows ( which is pretty much the same as the DDK sample ) is pretty nightmarish as a result of this and the non-contiguous memories. Of course, this is relevant for the file capture only. .a p.s. cute color effects could be achieved if direct overlaying is done in a 24 bit mode :) Trent Piepho wrote: [snip]
