- Optional Unicode/Encoding Support (with unicode version of wxPython).
- Easy Access to DrPython Commands:
- Customize the Right Click Pop Up Menu, Keyboard Shortcuts, and an optional ToolBar.
- Extensible in Python
- Plugins have complete access to DrPython internals.
- They can be loaded automatically on startup, or loaded in groups via the menu.
- Built in methods to facilitate adding plugin functions to the pop up menu, eyboard shortcuts, and the toolbar.
- Sriptable in Python
- Quickly write custom python scripts with access to DrPython internals, and access them from the menu,shortcuts, the pop up menu, or the toolbar.
- Quick Access to Files
- Bookmarks (which are built into the File Dialog) provide quick access to files and directories.
- The "Open Imported Modules" dialog enables you to get at modules imported in the document.

Python Palace Screensaver 0.1 is a new, marvelous sceensaver which brings you high-color photos of pythons from around the world. If you're a snake enthusiast, this is the screensaver for you. Features include numerous transition effects and the ability to control background colors, image intervals, effect speeds, image sizes and sequences, and whether to play or mute music.

Adds image processing capabilities to your Python interpreter The Python Imaging Library supports many file formats, and will provide you with powerful graphics capabilities and image processing.
This library provides extensive file format support, an efficient internal representation, and fairly powerful image processing capabilities.
The core image library is designed for fast access to data stored in a few basic pixel formats. It should provide a solid foundation for a general image processing tool.
Image Archives
The Python Imaging Library is ideal for for image archival and batch processing applications. You can use the library to create thumbnails, convert between file formats, print images, etc.
The current version identifies and reads a large number of formats. Write support is intentionally restricted to the most commonly used interchange and presentation formats.
Image Display
The current release includes Tk PhotoImage and BitmapImage interfaces, as well as a Windows DIB interface that can be used with PythonWin and other Windows-based toolkits. Many other GUI toolkits come with some kind of PIL support.
For debugging, theres also a show method which saves an image to disk, and calls an external display utility.
Image Processing
The library contains basic image processing functionality, including point operations, filtering with a set of built-in convolution kernels, and colour space conversions.
The library also supports image resizing, rotation and arbitrary affine transforms.
Theres a histogram method allowing you to pull some statistics out of an image. This can be used for automatic contrast enhancement, and for global statistical analysis.
System requirements:
- Python 2.2 or above

DISLIN for Python 2.5 9.4 is a useful software which is designed to display data graphically. It is intended to be a powerful and easy to use software package for programmers and scientists that does not require knowledge of hardware features.
