Fotoxx : A photo editing and collection management application

Fotoxx is a photo editing and collection management application. It lets you navigate an image collection using a thumbnail browser, import camera RAW files and edit them with 16-bit color, save edited images as TIFF-8/16, JPEG, or PNG, and edit the whole image or a selected area with adjustable edge blending. It supports multiple undo/redo. Tags, dates, and ratings can be added to images, which can be searched using these criteria as well as file names. Functions include brightness and color adjustments, trim, rescale, rotate, warp, sharpen, blur, noise reduction, red-eye removal, HDR composites, tone-mapping, and panorama.

Galapix : An image viewer that allows you to directly zoom into large collections of tens of thousand of images

Galapix is an image viewer that allows you to directly zoom into large collections of tens of thousand of images from tiny thumbnails down to the images' original size fluently with short load times and no loss of interactivity. It accomplishes this by keeping a tile cache which stores not only thumbnails for one size, but thumbnails of many different sizes.

ComicMaster : A CBR/CBZ reader for comic archives

ComicMaster is a CBR/CBZ reader for comic archives. It is able to open CBR and CBZ archives and display image contents. It allows you to add and remove single images, reorder images, and rename images in archives. It has some functionality to verify archives, and provides means to conveniently sort archives in a different folder. Those features are fairly well tested. It allows you to load a database plugin to manage comics in a PostgreSQL database, and it allows you to add meta-information in XML format to archives. The implementation of these features is currently sketchy at best.

white_dune : A graphical VRML97/X3DV editor

white_dune is a graphical VRML97/X3DV editor, simple NURBS/Superformula 3D modeller, animation tool, and a very limited 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.

Fotoxx : A program for improving digital photos

Fotoxx is a program for improving digital photos. Navigate large image collections using a pageable window of thumbnails. Create HDR (high dynamic range) images by combining bright and dark images to improve detail in both bright and dark areas. Create panoramas by joining overlapped images. Adjust brightness and color intensity independently for different underlying brightness levels. Rotate an image (level a tilted image or turn 90 degrees). Remove red eyes from electronic flash photos. Sharpen, resize, crop, reduce noise, and change color depth. Warp an image by dragging the mouse. Edit tags/keywords and search images by date or tags.
