Hi!
To test the scripting facilities I wrote a rudimentary html import filter.
Working with the plugin is really fun - the api is good documented and
really easy :-)
Unfortunately for a complete filter I would need extended bindings.
For example I only can set the font size for a complete textbox (selecting
text regions would be nice!) and I don't have access to styles.
There is a great potential for extensions I think.
Even some larger (less time consuming) core parts could be done in Python in a
much faster easier way than in C++.
Besides better access to the document and its objects it would be cool if I
could connect my script to other menus or toolbar buttons.
The attachment contains the html import filter.
