I have found a problem when I save Visio document to HTML and this document has helper lines inside.
Here is a sample project:
VisioTest.zip (167.4 KB)
Steps to reproduce:
- Open project in Visual Studio and run it
- Select a destination folder and press a button
- In the destination folder you should find generated HTML file. It contains big white space because of the helper lines (theycan be made visible by opening the document and zooming out a lot. Eventually you will see these helper lines far to the left of the actual drawing):
helperLines.png (20.5 KB)
Here you can see the differences:
VisioResult.png (89.4 KB)
AsposeResult.png (75.9 KB)
If I delete these helper lines, aspose works correct.
If you need more info, please let me know.
