Shapes streched or skewed after writeback

using this very simple c# code:
Aspose.Slides.License license = new Aspose.Slides.License();
Presentation presentation = new Presentation(@“C:\Mapping.ppt”);

mangles the position of some of the shapes (but not others)

Dear Daren,

It is not a bug actually. The shapes shrinks, because of empty textframes and because Resize AutoShape to fit text is set to true. Even if you open the presentation, just move a shape little, it will automatically resize and shrink. So you need to uncheck them.

For more information please see this thread.
