LibRaw is a library for reading RAW files obtained from digital photo cameras (CRW/CR2, NEF, RAF, DNG, and others). LibRaw is based on the source codes of the dcraw utility, where part of drawbacks have already been eliminated and part will be fixed in future. The users of the library are provided with API to be built into their software programs. LibRaw is intended to be used in any software that involves RAW file processing for a variety of purposes: RAW converters, data analyzers, panorama stitchers, noise suppressors, etc.

sam2p is a UNIX command line utility written in ANSI C++ that converts many raster (bitmap) image formats into Adobe PostScript or PDF files and several other formats. The images are not vectorized. sam2p gives full control to the user to specify standards-compliance, compression, and bit depths. In some cases sam2p can compress an image 100 times smaller than the PostScript output of many other common image converters. sam2p provides ZIP, RLE and LZW (de)compression filters even on Level1 devices.

Gmerlin is a multimedia framework, which allows you to quickly develop multimedia applications. It is built upon gavl (for low level Audio/Video things) and libxml2 (for loading and saving configuration data and other things). The gmerlin API can be used at multiple levels: Either you take the basic things like plugins, fifos, message-queues and gavl audio/video converters and build your own media engine. The other possibility is to use the player or transcoder engines directly. The latter approach is probably easier, but you'll have less freedom in controlling the process. Gmerlin includes GUI player with mediatree and a GUI transcoder among other things.

PerlPoint is both a presentation and a documentation toolset. More precise, its a toolset to generate presentations and documentations. You will write a simple text and start a converter to make the final documents from this source. The final format is your choice, depending on the used converter. So you can make a presentation, speaker notes, handouts, an internet documentation and a brochure all from the same text source, but looking very individual. Because of this two step architecture PerlPoint authors deal both with the text format and several converters. The text source describes structure and contents of your document, while a converter adds layout. Let's start.

JBIG-KIT implements a highly effective data compression algorithm for bi-level high-resolution images such as fax pages or scanned documents. This is a portable library of compression and decompression functions with a documented interface that can be included into your image or document processing software. Also provided are ready-to-use compression and decompression programs with a simple command line interface (similar to the converters found in Jef Poskanzer's PBM conversion package). JBIG-KIT implements the specification International Standard ISO/IEC 11544:1993 and ITU-T Recommendation T.82(1993), "Information technology - Coded representation of picture and audio information - progressive bi-level image compression", <http://www.itu.ch/itudoc/itu-t/rec/t/t82_23822.html>, which is commonly referred to as the "JBIG standard". JBIG (Joint Bi-level Image experts Group) is the committee which developed this international standard for the lossless compression of images using arithmetic coding. Like the well-known compression algorithms JPEG and MPEG, also JBIG has been developed and published by the International Organization for Standardization (ISO) and the International Telecommunication Union (ITU) (see also <http://www.iso.ch/> and <http://www.itu.ch/>).

Darktable is a virtual lighttable and darkroom for photographers: an open source photography workflow application and raw image developer. It manages digital negatives in a database and lets one view them through a zoomable lighttable. It also enables one to develop raw images and enhance them. Darktable tries to fill the gap between many excellent existing free raw converters and image management tools (such as UFRaw or F-Spot). The user interface is built around efficient caching of image metadata and mipmaps, all stored in a database. The user will always be able to interact, even if the full resolution image is not yet loaded. All editing is fully non-destructive and only operates on cached image buffers for display. The full image is only converted during export. The frontend is written in Gtk+/Cairo, the database uses SQLite3, raw image loading is done using libraw and rawspeed, high-dynamic range and standard image formats such as JPEG are also supported. The core operates completely on floating point values, so darktable can not only be used for photography but also for scientifically acquired images or output of renderers (high dynamic range).
