PyParticles is a particle simulation toolbox entirely written in Python. It simulates a particle-by-particle model with the most popular integrations methods, including Euler, Runge Kutta, and Midpoint. It represents the results on an OpenGL or Matplotlib plot, and offers an easy-to-use API.
Multipe Image Resizer Script is a PHP class which can resize images in several ways. It can take an image in JPEG, PNG, or GIF format and resize it to exactly the given width and height, the given width, keeping the original proportions of the height, the given height, keeping the original proportions of the width, an automatically-determined given width or height, keeping the proportions of the other dimension, or a cropped area, keeping the original proportions. The class comes with a script which can call the class to resize many images at once.
Raster is a library of raster image operations. Raster uses a graph method, where each node represents an operation. The root nodes of the graph are the resulting output images. Leaf nodes of the graph are sources of input data. Nodes in between represent operations on their children. Cycles in the graph must not be made.
aicwl is an Ada library that is intended for designing high-quality industrial control widgets for Ada applications. The widgets are composed of transparent layers drawn by cairo. The widgets are fully scalable graphics. A time controlled refresh policy is supported for real-time and heavy-duty applications. The library supports caching graphical operations and stream I/O for serialization and deserialization. Ready-to-use gauge and meter widgets are provided as samples as well as an editor widget for WYSIWYG design of complex dashboards. The software is based on GtkAda and cairoada, the Ada bindings to GTK+ and cairo.
DelVJ is a live video mixer VJing program for realtime video 3D composition and algorithmic video remixing of multiple sources such as multitrack video inputs from Firewire cameras, video media files, Puredata video channels, images, and text and RSS news feeds. It can send these sources to multiple outputs such as recording to hard disk and streaming to the Internet, local net, and screens. DelVJ can be controlled through OSC, and has interfaces for the Web and GTK. DelVJ allows multiple users to work on collaborative live video mixing projects for events, live broadcasts, artistic displays, and lighting effects. DelVJ aims for the flexibility and convenience needed for Pixel fests of many kinds.
