| The settings for Dave's Affine tool and Image Magick's Affine differ in their arrangement. "S" means scale (resize); "R" means rotate; "T" means angle of shear-transformation. "X" means width"; "Y" means height. DAVE: sx, rx, tx, sy, ry, ty IM's: sx, rx, ry, sy, tx, ty As you can see, Dave arranged the 3 "X" functions first, followed by the 3 "Y" functions. Dave says that the rotate (r) and angle of shear (t) for "Y" don't seem to do anything. | ||||||||||

| Remember that although the order of the numbers seems different, the numbers for each parameter are the same. And the results are the same. There are only two real differences between Dave's Affine and IM's. So from now on, I'll be using Dave's Transform-Affine tool instead of IM's.
