GraphicsMagick is the swiss army knife of image processing. It provides a robust 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, SVG, and TIFF. GraphicsMagick ... [More] supports huge images on systems that support large files, and has been tested with gigapixel-size images. GraphicsMagick can create new images on the fly, making it suitable for building dynamic Web applications. GraphicsMagick may be used to resize, rotate, sharpen, color reduce, or add special effects to an image and save the result in the same or differing image format. [Less]

LibTIFF provides support for the Tag Image File Format (TIFF), a widely used format for storing image data. Included in this software distribution is a library, libtiff, for reading and writing TIFF, a small collection of tools for doing simple manipulations of TIFF images, and documentation on ... [More] the library and tools. Libtiff is a portable software, it was built and tested on various systems: UNIX flavors (Linux, BSD, Solaris, MacOS X), Windows, and OpenVMS. It should be possible to port libtiff and additional tools on other OSes. [Less]

WebMagick recurses through directory trees, building HTML pages, imagemap files, and client-side/server-side maps (or HTML tables) to allow the user to navigate through (optionally) viewer-configurable collections of thumbnail galleries on the Web.
