dosberg Posted January 11, 2007 Share Posted January 11, 2007 Anyone know how I can add a crop function to Ciprian Voicu's Pictoru's Thumb class. The code is below. I would like to output an image that is cropped from the center of the image with equal height/width (a perfect square).

cheezylu Posted April 1, 2007 Share Posted April 1, 2007 This may help.Here is a modified code from lixlpixel of PHP Paradise.
