white_dune is a graphical VRML97/X3DV editor, simple NURBS/Superformula 3D modeller, animation tool, and VRML97/X3DV commandline compiler in development. VRML97 (Virtual Reality Modeling Language) is the ISO standard for displaying 3D data over the Web via browser plugins ("HTML for realtime 3D"). X3DV is the direct successor of VRML97. VRML97 and X3DV have support for animation, real-time interaction, and multimedia (images, movies, and sounds). white_dune can read, create, and display VRML97/X3DV files and let the user change the scenegraph/fields. It also has support for stereoscopic view via "quadbuffer"-capable stereo visuals, and support for 3D input devices like a joystick, spaceball, or magnetic tracker.
The XMMS Picture Viewer Input Plugin adds picture support to XMMS for various image formats. The picture is displayed for a (configurable) time. In conjunction with XMMS playlists, this makes it possible to create slideshows very easily, e.g. opening a directory that contains picture files directly starts the slideshow.
PAT draws small-scale (world and country-level) physical, political, and statistical maps, and flexibly lists information about world places. It does what a traditional paper atlas does, but interactively. PAT's intended user is the student, hobbyist, researcher, webmaster, or other non-professional. PAT is designed to be portable; it has the bare minimum of operating-system dependencies and is written in stable, well-known C. Any system with an ANSI C compiler and ISO runtime libraries can run PAT. PAT's abstract device model can accomodate any raster device; it comes with drivers for TTY, GIF, JPEG, PNG, X11, GRX, and others. PAT is multilingual and supports Unicode. Program messages have been translated to English and French so far. PAT can be run interactively, or batch-style from the command line and/or with scripts.
mtPaint is a simple GTK+1/2 painting program designed for creating icons and pixel-based artwork. It can edit indexed palette or 24 bit RGB images and offers basic painting and palette manipulation tools. Its main file format is PNG, although it can also handle JPEG, GIF, TIFF, BMP, TGA, XPM, and XBM files.
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.
"Jpegpixi" is short for "JPEG pixel interpolator". It is a command-line utility which interpolates pixels in JFIF images (commonly refered to as "JPEG images"). This is useful to correct images from a digital camera with CCD defects. Jpegpixi is unique in that it tries to preserve the quality of the JFIF image as much as possible. Most graphics programs decode JFIF images when they are loaded, and re-encode them when they are saved, which results in an overall loss of quality. Jpegpixi, on the other hand, does not decode and re-encode the image, but manipulates the encoded image data, protecting the quality of the image as much as possible.
CVL is a library for image and data processing using graphics processing units (GPUs). It is suitable as a base for GPGPU applications. Cvtool is a general-purpose computer vision tool that is based on the CVL library. It works as a filter by reading streams of data from standard input and writing manipulated data and/or analysis results to standard output. Complex analysis tasks can easily be realized in scripts. Many image and video manipulation and analysis functions are included, as well as some advanced computer vision techniques.
