Libpixel vs GraphicsMagick: What are the differences?
Developers describe Libpixel as "One image, any size, every device". It is a realtime image manipulation service for any images that are available on the internet. It works by fetching images from an existing Image Source, processing them on the fly and responding with the modified image. On the other hand, GraphicsMagick is detailed as "The swiss army knife of image processing". GraphicsMagick is the swiss army knife of image processing. Comprised of 267K physical lines (according to David A. Wheeler's SLOCCount) of source code in the base package (or 1,225K including 3rd party libraries) it provides a robust and efficient collection of tools and libraries which support reading, writing, and manipulating an image in over 88 major formats including important formats like DPX, GIF, JPEG, JPEG-2000, PNG, PDF, PNM, and TIFF.
Libpixel and GraphicsMagick can be categorized as "Image Processing and Management" tools.
