janko/image_processing: High-level image processing wrapper for libvips and ImageMagick/GraphicsMagick

Provides higher-level image processing helpers that are commonly needed when handling image uploads. This gem can process images with either ImageMagick/GraphicsMagick or libvips libraries. ImageMagick is a good default choice, especially if you are migrating from another gem or library that uses ImageMagick. Libvips is a newer library that can process images very rapidly (often multiple times faster than ImageMagick).
