Hello.
We are using Aspose 13.3.0.0 (same issue for 13.2.0.0) to save .pptx files to html format. The text that has column orientation is rendered as if it has common landscape orientation. This problem exists only for .pptx files, the same slide saved as .ppt produces correct html.

Rendered HTML: http://img829.imageshack.us/img829/1859/renderedcolumntextorien.png
The original .pptx file is also attached.
Thanks
