File with SmartArt WedgeRectCallout

Open attached document in PowerPoint and in LibreOffice. Notice the notch in the right shape in LibreOffice.

The problem is, that LibreOffice is not really wrong, but we need a workaround for an error in PowerPoint. I have reported the problem to MicroSoft (see URL), but have not got a solution yet.

The problem exists with normal shapes too as we use the custGeom for import from pptx. Only that for a normal shape it is unlikely, that the user drags the handle to inside the rectangle. But the SmartArt uses the default handle position 0,0 and it cannot be changed by the user.

I have reported the problem in Microsoft Forum
https://docs.microsoft.com/en-us/answers/questions/928553/actual-rendering-of-wedgerectcallout-is-different.html

According there answer, the definition in presetShapeDefinitins.xml needs a correction. It points me to https://mailman.vse.cz/pipermail/sc34wg4/2018-November/004555.html
That has a document attached with proposed changes.

I have that document attached here.
Comment 4 Regina Henschel 2022-07-30 13:47:19 UTC
The proposed changes in the custGeom work in PowerPoint. If we use this changes, it might be necessary to adapt the calculations in EnhancedCustomShape2d.cxx. I have not tested that.
