["hhMockup" is an enhanced version of the stack I used to produce the demos for my LCGlobal talk "Perspective and affine transformations of images" in Nov 2017.]
The stack contains a *very fast* version of the perspective image-transformation given in Raspberry Pi stacks collection #85 (pure LC Script): JavaScript is used for the lengthy transforms of the imageData and applying a few image filters. Everything else, especially the computation of the "perspective matrix" and all the display is still LC Script. You can scale, skew, translate and rotate in single or combined actions and perspective transform images up to screen size. *** The perspective transform is also used to show images in a given MOCKUP frame. There is also demo of running a gif (EM's jockey) in such mockup frames. There are still more details to explore, e.g. expanding the transform of the control polygon (and by that the image) horizontally, vertically or both. Download "hhMockup" from "Sample Stacks" (or http://livecodeshare.runrev.com/stack/867). The stack is tested to run using LC 8/9 on Mac/ Win 7+10/ Ubuntu (a few issues on linux, use latest LC 8/9 there). You can import your images and export your transformed artwork. Have fun! _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
