Asido is an image processing solution for programs written in PHP 4 or PHP 5. It features "pluggable" drivers (adapters) for virtually any environment: either GD2, ImageMagick via shell, ImageMagick via the PHP extension, Magick Wand, or others. It offers the following functionality: resize images, watermark images, rotate imatgs, copy images, crop images, grayscale images, convert images, etc.
BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
Eyefi I2 is an API for the abstraction of all common image transformations (thumbnailing, scaling, borders, etc.) into an XML file. Through a simple PHP API, images can be loaded through such a transformation to generate and cache a modified image. By stacking the image operations, very complex transformations can be accomplished, incorporating source images, generated text, image overlays, and more.
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.
GAIA Image Transcoder (GIT) is a library that operates image transcoding, with a special focus on mobile applications. It comes in two parts: a transformation and transcoding library that performs image adaptation to mobile device using information retrieved from WURFL files, and a very simple JSP tag library that enables library utilization in a J2EE environment. The transcoding library works as a transformation pipeline. The pipeline is composed of a set of filters. A filter can operate directly on the image body, or indirectly on the associated meta-information. The GIT architecture supports the management cycle of such pipes, while GIT tag libraries simplifies their definition.
GL2PS is a C library providing high quality vector output for any OpenGL application. It uses sorting algorithms capable of handling intersecting and stretched polygons, as well as non manifold objects. It provides advanced smooth shading and text rendering, culling of invisible primitives, mixed vector/bitmap output, and much more. It can currently create PostScript (PS), Encapsulated PostScript (EPS), Portable Document Format (PDF), and Scalable Vector Graphics (SVG) files, as well as LaTeX files for the text fragments.
HPGS is an HPGL/2 interpreter, which renders HPGL/2 and processes vector data through a Postscript-like API. It can render to EPS and PNG files. For rendering the scenery to pixel formats, it includes a rendering engine which draws vector graphics into pixel buffers. It also interprets inline PCL images.
