>And AggPas already has support for that pixel format
How do I define that as the format I want? I've been looking all through the
example and do not see how this is defined. I've attached a test program, it's
basically Graeme's sample but going to screen instead of a file. I just don't
see
le to use a nested loop and putpixel() but
that is very slow. I still think something is missing with putimage because I
don't see how it knows the shape of the image, maybe I need to actually do a
getimage() at some point to set the shape of before putimage will work.. I'll
t because I would like to figure out what I will need to do
on my target installations where freepascal will not be installed.
Any ideas on what causes this error and advice on how to install what is
needed on client (non-development) systems?
