Prima is an extensible Perl toolkit for multi-platform GUI development. Supported platforms include Linux, Windows NT/9x/2K, OS/2, and UNIX/X11 workstations (FreeBSD, IRIX, SunOS, Solaris, and others). The toolkit contains a rich set of standard widgets and has emphasis on 2D image processing tasks. A Perl program using Prima looks and behaves identically on X, Win32, and OS/2 PM.
ps2tiffs extracts the sampled images from a PostScript document. It is not a PostScript renderer. ps2tiffs is a system where the grazer feeds on the output of a PostScript interpreter whose image operators have been replaced by special data-hijacking functions. This has the benefit of allowing the extraction of images regardless of how they have been encoded, formatted, scaled, or squished by the app which generated the PostScript document. It outputs greyscale, RGB, and CMYK TIFFs.
libAfterImage is an image import, storage, manipulation, and output library for X. It features support for antialiased, TrueTypei, and X text, a 128-bit internal graphics engine, in-memory RLE image compression, high quality image scaling/flipping/blending, multipoint linear gradients, superior quality image output on X drawables, and much more.
Image Viewer is a multi-frame (animated) image viewer with real-time interactive pan and zoom viewing that uses the GTK+ toolkit and Imlib. It is capable of opening and saving to any image format supported by Imlib. It features screenshots (screen capture), crop, resizing, print, fullscreen display, display on the desktop (root window), animation (creating animated GIFs), color leveling, drawing font/text strings, and editing image header information.
Shapefile C Library is a C library for reading and writing ESRI Shapefiles and their related DBF files. All geometry types are supported, with robust DBF support. Shapelib is widely used for commercial and free projects. Shapelib includes command line utilities for dumping, subsetting, clipping, shifting, scaling, and reprojecting shapefiles.
Jitac is a Java application that converts images into ASCII art by associating blocks of the image with ASCII characters. It supports several image formats (GIF, JPEG, TIFF, and PNG) and some image manipulations that can be performed before the conversion (inversion, grayscale, resize, and gamma correction).
