When I set the transparency as 100% in 'Text Option' -> 'Text Contour'in MS Office, then those text is not shown in LibreOffice Impress.
Steps to Reproduce:
In MS office,
1. Draw Rectangle box
2. Input any text in rectangle box
3. Set Text Transparency as 100% in 'Text Option' -> 'Text Contour'
Those text isn't shown in LibreOffice Impress.
Those text should be shown like MS Office.

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).

May I ask you whether you have a plan to fix this problem ?
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.
LibreOffice doesn't have a concept of text outline AFAICS. So it needs to merge the text-fill with the outline-fill in a meaningful way.
Here is what I think needs to happen.
-when importing a:ln (text outline), then the colour should only be applied to the text only if the line transparency is greater than the text transparency.
-that will be a little tricky if the colour is inherited from a style.
// TODO unsupported yet
// case A_TOKEN( ln ): // CT_LineProperties

secretB.pptx: testing various transparencies, as well as a uLn (underline)
The hand-created uLn part seems to be skipped (even when I uncomment it in the code) and does nothing in PowerPoint 2016. Perhaps I did it wrong.
