Hi cafe!
I want to do some trivial masking manipulation on PNG images: take a picture, crop it to square shape and then make a circular mask, i.e. take all pixels that lies outside circle with radius equal to half of image width and placed at image center and replace that pixels with zero opacity once (hope this description is clear enough).
I've found two packages for image processing so far: `friday` [1] and `unm-hip` [2], but can't figure out which of them suits my needs, maybe there are some other packages I miss?
