yes, unbelieveable oversight. Thanks alot Mark .. I was concentrating so
much on what I don't know, when the mistake was somewhere else ... part of
what I _should_ know about.
will check out other way as well though.
Many thanks.

I'm pretty sure the following lines should read:

if(k==0)
tmp_frame->data[0][y*tmp_frame->linesize[0] + 3*x +k]= ((gdim-

}
There is probably a quicker and easier way of copying the buffers.
Although I've never used GD so don't know how it stores it's image. You
might be able to use an RGB32 buffer and do a straight memcpy() per line.
