Since the first release of our filter in LibreOffice 3.5.0, we were improving it thanks to bug reports from our users. It is a big thank you that I would like to say to all those that took the bother to submit reports in our bugzilla. Without you, guys, this filter would be only a moot exercise.
But wait... Do I write this blog now only to thank the people who contributed to the current quality of the filter? Yes to a big extent! Nevertheless, I know that the distinguished readers of this blog would like to have some news. And, yes, we have some news.
libvisiolibrary underwent heavy re-factoring as we started to understand more and more details about the underlying file-format.
- A particular bug report about files imported as empty pages provided us with a document structure that we did never see before. This resulted in a more generic parser and unification on the way we parse master shapes and visible pages.
- This re-factoring in its turn allowed us to extend our file-format coverage to all earlier binary Visio file-format versions. We now support all binary Visio documents starting from Visio 1 (released in 1992).
- Extending the support to earlier file-format versions allowed us to better understand the development of the file-format, to find more information that we did not parse before, and improve the conversion quality for other binary versions too.
- Another re-factoring came with our work to support the
XML-based Visio file-formats, namely the "XML Drawing" also known as
*.vdx; and the Microsoft Visio 2013 new file-format, known as
And since the readers of this blog are more interested in pictures than in pointless words, here come some candies for your eyes:
