PPTX compared MSO 2016 LO 7.1+

No repro 6.4. Repro LO 7.0 and 7.1+. Regression.
It's Text Outline Transparency in MSO.

oox: add PPTX import/export for semi-transparent shape text
And start a drawingml test suite in oox, so the test and the tested code
is close to each other (just like how it's done in chart2/ already).

Dear.

May I ask you whether you have a plan to fix this problem ?
Comment 5 Miklos Vajna 2020-11-18 07:44:21 UTC
Yes, I plan to, unless somebody else is faster to look at this. However, I'm not short on problems right now. So if you need this urgently, please see <https://www.libreoffice.org/get-help/professional-support/>, thanks.
