Hello,

I need to display graphics on the form (objects and line moving
from here to there, graphs, and so on...) which one is better to
use on the form? TImage or TPicture? what's the different between
them? (as i understood TPicture is actually part of TImage...).

Also which method is better to use - BitBlt or CopyRect?

I care a lot here about fast graphics and no flickering problems.

Thanks,
Ramy

Also, what's the different between the performens of StreachBlt
and CopyRect? it's looks like they are doing exactly the same,
which one is better to use and why?

Thanks,
Ramy
