Apache XML Graphics Commons is a library that consists of several reusable components used by Apache Batik and Apache FOP. Many of these components can easily be used separately outside the domains of SVG and XSL-FO. You will find components such as a PDF library, an RTF library, Graphics2D implementations that let you generate PDF and PostScript files, and much more.
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.
The Enhanced MetaFile format (EMF) is the native vector graphics file format on Windows. Qt is a cross-platform application development framework, widely used for the development of GUI programs. Although it provides tools for almost every aspect of software development, Qt doesn't include a straightforward solution for the export of 2D graphics to the EMF format. EmfEngine covers this lack and enables Qt-based applications to easily export graphics to the Enhanced Metafile format.
Enscribe creates digital audio watermark images. The rasterlines of an image are converted into frequency components via an inverse fast fourier transform. The watermarks sound like soft hissing, but when viewed in a frequency-versus-time display, the image is clearly visible. Manipulation of the audio file, such as by MP3/Ogg compression, reverb, or flange, muddies the image, but it remains visible.
Eyes Of Lynx is a Web-based application that allows you to share, examine, and manage your photo albums. It's designed to be fast, intuitive, and very powerful. Its key features include an original and innovative interface, zoom and rotation tools, auto-rotation of photos when an orientation is provided in EXIF data (information stored by digital cameras), a cache of images in a smaller/intermediate size to increase display and loading speeds, thumbnail image navigation, and more.
