nifty... this should at least allow placing from world file w/ rotation parameters. for manual placement via geometry i will probably resort to bruteforce warping the picture within it's 4 corners, if i get it to work at all. additionally we could use the ImgLayerMgr "Reset Placement" (to original georeference or 0,0 default) and "Place Manually" (bbox or even better 4 coordinates for the corners and rotation angle, analogous to wld file data) buttons the second will be probably some work (gui design, pfhhhh). so i'll probably not realize it for now. thx.. ede ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
