Fotoxx navigates an image collection using a thumbnail browser to choose images to view or edit. Edit functions include brightness, contrast, color, gamma, white balance, tone mapping, red eyes, sharpen, blur, noise suppression, smart erase, trim (crop), resize, rotate, add text, bend/warp, many art effects, HDR, HDF, stack, and panorama. Edit functions use movable curves and sliders. Feedback is live using the whole image. RAW files can be edited and saved with deep color. Areas or objects can be selected using freehand draw, follow edge, and tone matching. Selections can be edited in place with adjustable blending. They can also be cut and pasted into other images. Any metadata can be edited, reported, and searched (filenames, tags, dates, geotags, comments, captions, ratings, etc.). Collections (arbitrary subsets) can be defined and viewed. Batch functions are available for rename, resize/export, RAW conversion, and more.
This is a set of brushes and patterns (other items may be added later) for use with the GIMP. Many of the brushes are converted from other formats that have been made available for use with other packages on different platforms. These data files are meant to compliment the Graphics Muse Tools plugins, but are not required by that package.
GTKRawGallery is a workflow-oriented photo retouching program with the necessary tools to quickly process camera raw images. It brings together Dcraw, Imagemagick, and Exiftool. Important features include an image browser and manager for popular formats, a full-featured Dcraw GUI for fine-tuned raw image pre-processing, image modification tools for 16-bit/channel post-processing, batch conversion with single workflow applicable, a batch processor to speed up the workflow, fast tagging, an advanced metadata editor with EXIF, IPTC, and XMP write support, color management, and print support, Facebook, Flickr, and Picasa Web Albums publishers, and a Dropbox uploader.
Evolvotron is an interactive "generative art" application to evolve images/textures/patterns through an iterative process of random mutation and user-selection driven evolution. If you like lava lamps, and never got tired of the Mandelbrot set, this could be the software for you. It's implemented using Qt, and is multithreaded.
Citra FX is a set of image filter effects for digital photos or images. It allows anyone, regardless of experience, to turn digital images into unique artistic looks. Citra FX comes with many prebuilt filters from color adjustment, contrast, and exposure to advanced filters like water ripple, emboss, etc. You also get instant visual feedback on what you changed. It is well suited for both simple and advanced digital photo or image filtering.
Geomajas is an extensible spatial application framework, enabling integrated GIS solutions for businesses and government. It has an integrated client-server architecture, with a high focus on server-side integration of your data (be it through GeoTools or Hibernate). This means that you apply your security and business logic on the server before anything gets sent to the client, resulting in robust applications and a real thin client.
Tux Paint is a simple and entertaining drawing program geared towards young children. It has a simple interface, sound effects, and a cartoon character (Tux, the Linux penguin). Along with drawing brush strokes, lines and shapes, you can also enter text and place "rubber stamp" (or "sticker") images on the picture. Tux Paint is extensible, and could be useful in an educational environment (such as a grammar, elementary, or grade school). It's portable across numerous platforms, and runs well even on slower systems like the Pentium 133MHz.
F-Spot is a personal photo management application for the GNOME desktop. It simplifies digital photography by providing intuitive tools to help you share, touch-up, find, and organize your images. These tools include editing, color adjustments, tags, Photo CD creation, and exporting for upload.
Raster3D is a set of powerful tools for generating high quality raster images of proteins or other molecules. The core program renders spheres, triangles, cylinders, and quadric surfaces with specular highlighting, Phong shading, and shadowing. It uses an efficient software Z-buffer algorithm that is independent of any graphics hardware.
