crop picture as circle in PHP

Question

Is it possible to crop a profile picture as a circle? I tried PHP crop, but the quality was awful. Color shades changed and image quality suffered. Is there any PHP library which does this properly? Or some Apche program?

Answer 1

You can not crop image to circle. Image must be rectangular. The best solution is to use css with border-radius property - border-radius: 50%. But if you really need a circle you can try to add a frame using ImageMagic. One of possible solutions: http://www.imagemagick.org/Usage/thumbnails/#badge_overlay
