TikZ-dependency allows you to draw dependency graphs in LaTeX documents with little or no effort. The package has a very easy to learn, high level interface that can be used to draw simple dependency trees, complex non projective graphs, bubble parses, and in general any kind of graph that is based on a sequence of nodes and edges among these. It is based on PGF/TikZ and can be used either with latex or pdflatex. It comes with very comprehensive documentation that will get you started in 10 minutes, even without any prior knowledge of TikZ. It also provides a lot of styling facilities to let you personalize the look and feel of the graphs.
Tree Layout Helper is a .NET/Mono library that provides some utilities for handling tree structures. Most importantly, it supports the display of tree structures as two-dimensional graphics. By using ready-made interfaces, you can specify the size of your nodes, and the Tree Layout Helper library will take care of placing those nodes appropriately.
crunch/crnlib is a lossy texture compression tool and library for developers that distributes and uses content in the DXT1/5/N or 3DC/BC5 compressed mipmapped texture formats. crnlib can compress mipmapped 2D textures and cubemaps to .8-1.25 bits/texel, and normal maps to 1.75-2 bits/texel. crnlib's quality and performance is competitive to transform-based solutions, or other offline/real-time DXTn compressors such as squish or ATI_Compress. crnlib implements a new form of "clustered" DXTn compression, with a compressed texture data format that was carefully designed to be very quickly transcodable directly to raw DXTn texture bits with no intermediate recompression step or individual pixel-level operations. The typical single threaded transcode to DXTn rate is equivalent to 100-250 megatexels/sec. Fast random access to individual mipmap levels is supported.
Image Font can render images with text, using graphics as fonts. It takes a text string and creates an image on which the characters of the string are displayed using separate image files to render each character. The text may be aligned to the left, right, or center, or be justified. The image width may be limited so the text is wrapped if it exceeds the width limit. The character graphics may be mapped to image files with the same base name in a given directory. Alternatively, an array may be passed to define the paths of the character image files. The generated image may be saved to a file or displayed as the current script output in any of the formats supported by the PHP GD image extension.
Isoworld can render 3D isometric cubes from three page elements. It takes the identifiers of three page elements and adjusts their CSS transform properties so they form the faces of a cube which appears in the page with the 3D isometric perspective. It can also use a fourth element to be displayed as the shadow of the cube on top of another element which appears as the ground.
Calligra is an integrated suite of applications that cover office, creative, and management needs. It offers applications on both desktop computers and mobile platforms like tablets and smartphones. OpenDocument Format (ODF) is used, making it compatible with OpenOffice.org, LibreOffice, and Microsoft Office. Calligra Suite contains the following applications: Calligra Words (word processor), Sheets (spreadsheets), Stage (presentations), Flow (diagrams and flowcharts), Kexi (visual database creator), Braindump (note taking), Plan (project management), Krita (drawing), and Karbon (vector graphics).
