GraphicsMagick is billed as the Swiss army knife of image processing.
It is a collection of tools and libraries which support reading, writing, and manipulating an image in over 89 major formats including important formats like DPX, GIF, JPEG, JPEG-2000, PNG, PDF, PNM, TIFF, and WebP.
GraphicsMagick is originally derived from ImageMagick 5.5.2. The command-line syntax and programming APIs remain upward compatible. In addition to the programming language APIs available with ImageMagick, GraphicsMagick also provides a Tcl API, called TclMagick.
Key Features
- Supports huge images and has been tested with gigapixel-size images.
- Multi-threaded image processing using OpenMP.
- Convert an image from one format to another (e.g. TIFF to JPEG).
- Resize, rotate, sharpen, color reduce, or add special effects to an image.
- Create a montage of image thumbnails.
- Create a transparent image suitable for use on the Web.
- Compare two images.
- Turn a group of images into a GIF animation sequence.
- Create a composite image by combining several separate images.
- Draw shapes or text on an image.
- Decorate an image with a border or frame.
- Describe the format and characteristics of an image.
- Image processing operations are available from the command line, as well as through C, C++, Lua, Perl, PHP, Python, Tcl, Ruby, Windows .NET, or Windows COM programming interfaces.
- Cross-platform support – runs under Linux, Mac OS X, and Windows.
