Disc-cover provides an easy way to produce covers for audio CDs. It scans audio CDs and uses information from the CDDB or CDINDEX database to build a back and front cover for the CD. Output is in Latex, Dvi, PDF, Postscript, HTML, plain ASCII, or any other format suited for cdlabelgen.
Trueprint is a program for printing source code in a variety of languages (C is the best supported) and other text files to postscript printers. It supports a wealth of options to support printing source code, such as diff-marking, line numbers, indentation levels, file and function indices, and many others.
GNU-barcode is meant to solve most needs in barcode creation with a conventional printer. It can create printouts for the conventional product-tagging standards: UPC-A, UPC-E, EAN-13, EAN-8, ISBN, and several others. Output is generated as either Postscript, Encapsulated Postscript, or PCL (other back-ends may be added if needed). The package is released as both a library and a command-line frontend, so that you can include barcode-generation into your application.
ICCLIB implements support for reading and writing of color profile files that conform to the International Color Consortium (ICC) Profile Format Specification, Version 3.4. The ICC Profile Format is a cross-platform device profile format that can be used to translate color data created on one device into another device's native color space. See the profile specification at color.org. In summary ICCLIB provides support for all version 3.4 header elements, Tags, and Tag Types, conversion to/from machine native representation of all data types, user-defined Tags, adding/deleting Tags, Tag type sharing within a file (often used for sharing LUTs amongst intents), reading/writing embedded profiles, a single function for transforming color values through a profile (including support for intents, forward and reverse transforms, gamut lookup or preview lookup), support and code examples for creating all profile types, monochrome, matrix, and Lut, and it loads Tag Types on demand to conserve memory space.
