Description Regina Henschel 2022-04-25 23:22:30 UTC
Created attachment 179769 [details]
example with ActionButton

Open attached document. It has a not square action button. The markup uses the attributes draw:path-stretchpoint-x and draw:path-stretchpoint-y. The purpose of these attributes is, that the width of the bevel area does not change, when you make the shape much wider. The width of the bevel area is only determined by the handle.

Save the document to pptx-format. Open in PowerPoint or reopen in LO. Notice, that the geometry is broken.
Comment 1 Regina Henschel 2022-04-25 23:27:04 UTC
I will fix it.

The solution is to use parameter value "true" in calling EnhancedCustomShape2d::GetParameter().

Set of further files for manual testing

Not all cases of commands are covered by unit tests. Here are some more files, which can be used for manual testing.
