I traced the code thru devdraw.c::GdArea and the image is correctly drawn in memory.
I printed the number of calls to drawpoint/drawrow with x,y locations and it makes sense for the image.
However, it then calls GdBlit and here for some reason it falls to 'Partly clipped' area of code.
The parameters are:
dstx = 456
dsty = 36
width = 24
height = 24
srcx = 0
srcy = 0
I believe these are OK and the size of array is good, but what makes is partly clipped?
I will work on this but any suggestions are welcomed.
Martin

All your results look good so far. Next step is to debug devdraw.c::GdArea.
I've checked this routine pretty well, there is code that attempts
to find multiple points of the same color. I'd add debug statements
that just show GdArea is called with the correct width and pixtype,
and then each dot for the full width is displayed.
