This is code implements the example given in pages 11-15 of An Introduction to the Kalman Filter by Greg Welch and Gary Bishop, University of North Carolina at Chapel Hill, Department of Computer Science.
This presentation was given as a scheduled talk at PyCon UK 2007. The material presented covered the following subjects: * Generating code from user interface descriptions with pyuic4 * Connecting signals and slots using auto-connection * Creating custom widgets with PyQt4 for use in Qt Designer
The Python Imaging Library uses a plug-in model which allows you to add your own decoders to the library, without any changes to the library itself. Such plug-ins have names like XxxImagePlugin.py, where Xxx is a unique format name (usually an abbreviation). A decoder plug-in should contain a decoder class, based on the ImageFile base class defined in the module with the same name. This class should provide an _open method, which reads the file header and sets up at least the mode and size attributes. To be able to load the file, the method must also create a list of tile descriptors. The class must be explicitly registered, via a call to the Image module.
