sam2p is a Unix commandline utility that converts many raster (bitmap) image formats into Adobe PostScript or PDF files. The images are not vectorized. It gives full control to the user to specify standards-compliance, compression, and bit depths. It is common that sam2p can compress an image down to an 50kB Level1 PostScript file without quality loss, while other popular converters produce multi-megabyte output. It provides some Level3 compression filters even on Level1 devices. platform: Unix license: GNU General Public License (GPL)

ImageMagick (TM) is a package for display and interactive manipulation of images for the X Window System. It is written in C and interfaces to the X library, and therefore does not require any proprietary toolkit in order to compile. Although the software is copyrighted, it is available for free and can be redistributed without fee. ImageMagick is known to compile and run on virtually any Unix system and Linux. It also runs under Windows NT, Windows 95, Macintosh, and VMS.


gen3img is a tool to automatically convert graphic files to three different sizes, in three different qualities (if allowed by the output file format). gen3img is designed to handle many files at a time, and you can recurse many subdirectories as well. It is especially useful if you have to set up a large Web site or photo album with the same pictures in different resolutions (to please modem users). gen3img is a powerful command line frontend to the ImageMagick "convert" command. platform: Linux license: GPL


The GD gif-manipulating library, version 1.2 was created to allow graphs, charts and the like to be generated on the fly for use on the World wide Web, but is useful for any application in which custom .GIFs are useful.

CADUBI draws text-based images that are viewable on typical UNIX-based consoles. It has support for all eight ANSI colors, and for the bold, inverse, and blink ANSI modes. It features a pico-like interface with a status bar, a text mode that lets you quickly type strings in the current color and/or mode, a Quick Help screen for easy key reference, and the ability to read any text file with ASCII art. It outputs files in plain text so they can be displayed using cat and read back into CADUBI.
