Pngrewrite is command-line utility that reduces the unnecessarily large palettes that some programs write into PNG files. It also optimizes transparency data, and reduces the bits-per-pixel if possible. Handy for post-processing PNG files before putting them on a web site.

PyChart is a Python library for creating high quality Encapsulated Postscript, PDF, or PNG charts. It currently supports line plots, bar plots, range-fill plots, and pie charts. Because it is based on Python, you can make full use of Python's scripting power.

GLEWpy aims to bring advanced OpenGL extensions to Python. This will allow the Python OpenGL developer to use features such as fragment and vertex shaders and image processing on the GPU. It serves as a complement to PyOpenGL and toolkits such as GLUT and SDL (pygame).

Pycha is a very simple Python package for drawing charts using the great Cairo library. Its goals are: * Lightweight * Simple to use * Nice looking with default values * Customization It won't try to draw any possible chart on earth but draw the most common ones nicely.

QtAwesome is a simple library that can be used to add Font Awesome icons to your Qt application. NOTE: Though the name is QtAwesome and currently it's very Font Awesome based, you can use every other icon/glyph font you want. The class can also be used to manage your own dynamic code-drawn icons, by adding named icon-painters.

webcolors is a simple Python (2.6, 2.7, 3.3+) module for working with HTML/CSS color definitions. Support is included for normalizing and converting between the following formats (RGB colorspace only; conversion to/from HSL can be handled by the colorsys module in the Python standard library): * Specification-defined color names * Six-digit hexadecimal * Three-digit hexadecimal * Integer rgb() triplet * Percentage rgb() triplet

The Tesseract OCR engine was one of the top 3 engines in the 1995 UNLV Accuracy test. Between 1995 and 2006 it had little work done on it, but it is probably one of the most accurate open source OCR engines available. The source code will read a binary, grey or color image and output text.

This is a GLX port of the Really Slick Screensavers collection (http://www.reallyslick.com/). Also included are several other OpenGL screensavers ported from other platforms. The screensavers can either be run as stand-alone applications or get integrated into XScreenSaver's list of active screensavers.

The PagedGeometry engine is an add-on to Ogre which provides highly optimized methods for rendering massive amounts of small meshes, covering a possibly infinite area. This is especially well suited for dense forests and outdoor scenes, with millions of trees, bushes, grass, rocks, etc.
