ruby-tmpl is used for the online and offline creation of HTML, XML, and email documents. Like many other templating languages, ruby-tmpl lets you abstract the presentation from the actual content of a document. However, unlike other templating languages, ruby-tmpl also lets you perform offline processing of documents so that you can have your Web server serve static content created by templates as well as dynamic content. The templating language itself is fully XML-compliant and can safely be embedded in XML documents.
PDF::API2 is 'The Next Generation' of Text::PDF::API, a Perl module-chain that facilitates the creation and modification of PDF files. It features support for the 14 base PDF Core Fonts, TrueType fonts, and Adobe-Type1, with unicode mappings, embedding of bitmap images, compression via zlib, and a rich object-oriented API.
Argyll is an ICC compatible color management system. It supports accurate ICC profile creation for scanners, CMYK printers, and film recorders, and calibration and profiling of displays. Spectral sample data is supported, allowing a selection of illuminants observer types, and paper fluorescent whitener additive compensation. Profiles can also incorporate source specific gamut mappings for perceptual and saturation intents. Gamut mapping and profile linking uses the CIECAM02 appearance model, a unique gamut mapping algorithm, and a wide selection of rendering intents. It also includes code for a fast 8-bit raster color conversion engine as well as support for fast, fully accurate 16-bit conversion. Device color gamuts can also be viewed and compared using a VRML viewer.
The HP Linux Inkjet Driver Project is a addon to GNU Ghostscript that provides basic printing support for more than 40 Deskjet printer models. Basic printing support means very good print quality and will generally work in two print modes -- plain paper normal, and photo paper best.
magicfilter is an extensible and customizable automatic printer filter. It selects an appropriate conversion technique for the input data by seeking for magic numbers, and then utilizing the appropriate conversion utility. It is primarily intended for use as the "input filter" by the lpd print spooler. The options accepted by magicfilter are exactly the ones passed to the input filter by lpd.
psdim is a small utility to be used in conjunction with pstops. It looks at the contents of a postscript document to determine the size of the printed pages. From this, it calculates the optimal placement of the pages for n-up printing. It outputs a format string suitable for processing by pstops.
