Howdy, Starting with a 100 x 20 image, I want to produce a trapezoid with corners at top left = 20,0 top right = 80,0 bottom left = 0,20 bottom right = 100,20
the image now has a 45 degree bevel at the ends. I've found that the data param to transform PERSPECTIVE, a,b,c,d,e,f,g,h represents:: (a x + b y + c)/(g x + h y + 1), (d x + e y + f)/(g x + h y + 1) I don't have the math skills to solve for the result I need. Any help is greatly appreciated. Thanks, Kent PS Why? I want to place an image within a larger image, with the smaller in a frame which blends between the two. This seamless embedding is quite a nice effect. The perspective effect is to miter the edges of the frame. At one time I implemented a crude version which just cropped the blended elements to 45 degree, now I want to revisit doing a proper transform. _______________________________________________ Image-SIG maillist - Image-SIG@python.org http://mail.python.org/mailman/listinfo/image-sig
