Netpbm

NetPBM (formerly PBMplus) is a package of over 220 programs that convert from one graphics format to another and do simple editing and analysis of images. There are no interactive tools in this package, and nothing that displays graphics of any kind. It is like a non-GUI equivalent of ImageMagick, GIMP, and Adobe Photoshop, etc. Over 100 graphics formats are handled, including JPEG, MPEG, PNG, GIF, TIFF, BMP, XWD, XBM, G3 fax, and special formats used by digital cameras and handheld computers. Over 40 editing functions include scaling, cropping, quantization and dithering, colorizing and uncolorizing, blurring, and dimming. Netpbm programs are often invoked by other programs, for example in CGI scripts that manage web site graphics. It also includes a C function library which helps you write programs to process graphics at a lower level than the Netpbm utilities.

    Release Notes: In the past year, 20 new programs have been added to the package, doing such things as converting to the image format used by a handheld wireless device to stitching together multiple panoramic photographs of a scene. This version has HTML documentation, with a current version kept on the Internet and local installation optional. It also includes a man-like program for viewing it for people who like the old way. An all new build process makes multi-system installation and distribution easier and reduces installation failures.
