This page brings together all the documentation that is currently available to help developers who are new to Xara LX get up to speed. Some of the documents were written a long time ago, but still contain relevant and useful information. You'll notice that many documents refer to 'Camelot' which is just a developer code name for the product that's stayed the same while the public name for the tool has changed many times!

Import/Export Filters

Xara LX supports a powerful mechansim that allows third parties to implement and test plug-in import and export filters, without building or changing Xara LX itself. Filters must convert data to and from the Xar format. We provide helpful example code (including a complete example filter), documentation and a helper library to make developing filters as easy as possible for external developers. See the filter development page for details.

Xar file format specification
The XAR format is the native file format of Xara LX, Xara Xtreme and many earlier versions of Camelot. The Xar Format Specification page provides a detailed PDF document describing the format, a support library to help read and write XAR files and a sample XAR file filter.
