- BRL-CAD includes an interactive geometry editor, parallel ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, image-processing and signal-processing tools.
- FLIF is a novel lossless image format which outperforms existing image formats in terms of compression ratio. It works well on any kind of image (photographic, line art, computer graphics, etc.) and also supports animations. FLIF images (or animations) can be progressively decoded, which makes the format potentially very suitable for responsive web design.
This is the reference implementation of FLIF, which includes a command-line tool (flif) to convert between FLIF and PNG/PNM/PAM, a decoding library (libflif_dec), an encoding library (libflif_enc), some scripts (gif2flif, apng2flif, raw2flif, ...), and a simple image/animation viewer (viewflif).
- The Gnu Data Language (GDL) is a free alternative to the data visualization and analysis tool, called IDL (Interactive Data Language), frequently used by scientists.
GDL and its library routines are designed as a tool for numerical data analysis and visualisation. GDL is dynamically typed, vectorized and has object-oriented programming capabilities. The library routines handle numerical calculations, data visualisation, signal/image processing, file input/output (incl. graphical and scientific data formats such as TIFF, PNG, netCDF, HDF etc) and interaction with host OS.
Despite its name, GDL is not a GNU package.
- HAP HTML as image
- HAP - "HTML as Picture": the technology allows you to create a fully adaptive Pixel Perfect html sites with dynamic scaling of all html-document elements. Nesting site is done using EM and quantities per cent instead of the usual PX.
- ImageJ is a public domain Java image processing program inspired by NIH Image for the Macintosh. It runs, either as an online applet or as a downloadable application, on any computer with a Java 1.4 or later virtual machine.
- KiCad is electronic design automation (EDA) software made for designing schematics of electronic circuits and printed circuit boards (PCB). KiCad is developed by the KiCad Developers Team, and features an integrated environment with schematic capture, bill of materials list, PCB layout and much more. KiCad is cross-platform, written with WxWidgets and runs on FreeBSD, Linux, Microsoft Windows and Mac OS X. A lot of component libraries are available. Also migrating tools for components are available (from other EDA software tools). File formats are plain text and well documented, which is good for CVS or Subversion and to make automated component generation scripts.
Multiple languages are supported, such as English, Portuguese, Spanish, Czech, Polish, French, German, and Russian.
The 3D PCB viewer use 3D model from Wings3D CAD.
- A collection of routines to create and manipulate PNG format graphic images. Designed as a replacement for GIF (and to a lesser extent TIFF) due to functional and patent problems, with more efficient compression (using Gzip-like DEFLATE), support for 24-bit color and alpha transparency.
- Orthanc aims at providing a simple, yet powerful standalone DICOM server. It is designed to improve the DICOM flows in hospitals and to support research about the automated analysis of medical images.
Orthanc can turn any computer running Windows or GNU/Linux into a DICOM store (in other words, a mini-PACS system). Its architecture is lightweight and standalone, meaning that no complex database administration is required, nor the installation of third-party dependencies.
What makes Orthanc unique is the fact that it provides a RESTful API. Thanks to this major feature, it is possible to drive Orthanc from any computer language. The DICOM tags of the stored medical images can be downloaded in the JSON file format. Furthermore, standard PNG images can be generated on-the-fly from the DICOM instances by Orthanc.
Orthanc lets its users focus on the content of the DICOM files, hiding the complexity of the DICOM format and of the DICOM protocol.
- ZBar is a software suite for reading bar codes from various sources, such as video streams, image files and raw intensity sensors. It supports many popular symbologies (types of bar codes) including EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 39, Interleaved 2 of 5 and QR Code.
The flexible, layered implementation facilitates bar code scanning and decoding for any application: use it stand-alone with the included GUI and command line programs, easily integrate a bar code scanning widget into your Qt, GTK+ or PyGTK GUI application, leverage one of the script or programming interfaces (Python, Perl, C++) ...all the way down to a streamlined C library suitable for embedded use.
