QuartzCrystal is an application for rendering Quartz compositions to QuickTime movies and image sequences. It supports third party plugins (using both the official and unofficial API), as well as unsafe patches. It also supports spatial supersampling (antialiasing) and temporal supersampling (motion blur).
Zen Flash Gallery CS3 Component is a tool for creating online presentations and slideshows from a set of images. It is based on Adobe Flash (CS3) technology. Source images may be read from multiple folders. Gallery parameters are configured via XML. Images may be given captions and sound effects.
Smitten differs from traditional media centres in three major ways. It contains no media playback at all, which makes it very small (and suitable for porting to embedded systems) and quick to initialize. It targets a TV display and interface, which means there's less information on any particular screen, and a much simpler control interface consisting of left, right, up, down, and select. No mouse is required. It is also highly skinnable, and cross-platform to most systems. Essentially, it provides an easy-to-use menu system that allows the user to navigate a hierarchy of files, and view them using an (external) tool.
retypar converts photos, drawings, etc. into text. The result can be saved as text, HTML, ANSI,or as an image (JPEG or GIF). You can influence the conversion by altering certain options (font, font size, scale factor, color etc.). This program is translated into German, English, French, Spanish, and Italian. In addition to the graphical interface, there is a batch mode that allows you to convert a number of pictures with a single command.
Mathnetics is an API for creating advanced, interactive, Web-based mathematical applications. It defines various important mathematical objects that are inter-related and on which many numerical calculations can be done. It also features rendering of 3D objects onto an SVG canvas (to do so, it includes certain utilities such as browser sniffing, DOM node selection, and DOM readiness detection), which is quite robust. A few basic 3D objects are given (Line, Sphere, Cube), but the user can define any 3D object desired as per the specification.
PTRANS reads P5 and P6 (PGM, PPM, PNM) files, and performs Floyd-Steinberg dithering and scaling while only holding two scanlines of image data at a time. It can be used on gigapixel images while only consuming a small amount of RAM. It outputs P4 (PBM) dithered monochrome bitmap and P5 (PGM) grayscale images. It performs pixel interpolation and smoothing. Gamma correction and contrast curves may be set from the command line.
