DIY examples of using a bilinear 'perspective' transform are now created. However it may be a day or so before they appear on the main IM Examples Web site http://www.imagemagick.org/Usage/distorts/#bilinear Anthony Thyssen ( System Programmer ) <[EMAIL PROTECTED]> ----------------------------------------------------------------------------- Aero ergo sum.
