DrawAdd draws an image with additive blending, which I thing you interpreted as being something else. To draw on the new surface normally, just use the regular Draw method. (Unless of course you want additive blending on the new surface?)Originally Posted by nildo
As a general note: The reason DrawAdd is so slow is because it has to do the blending manually (ie. software-based), since DelphiX uses (DirectDraw) software-rendering. Try to avoid blending routines in general with DelphiX unless you're using them with smaller images.
EDIT: Oh hey! Welcome to PGD, too.
