Description Gerald Pfeifer 2018-03-02 19:50:22 UTC
Description:
Saving a chart with blocks that use hatching as PPTX (regardless whether
the original came as PPTX or ODP) loses the hatching and replaces it with
solid color.

Steps to Reproduce:
1. Open sample document (in ODP format).
2. Save as PPTX.
3. Close and reopen saved PPTX.


Actual Results:  
Observe the difference where what used to be blocks with hatching now
show in solid color.

Expected Results:
Document does not visually change when saving as PPTX.


Reproducible: Always


User Profile Reset: No



Additional Info:
This originally came from a PPTX document, and the import from PPTX
to ODP with LibreOffice seems to have worked just fine.

The example file opened in current LO 6.3

A source of this problem is that there is a 0 line spacing set in the chart data series, but it is not displayed as such.
A hatching with 0 line spacing is indeed a different way of saying "solid fill".
Another angle is that in MSO it is not possible to select an arbitrary line spacing - this is hidden in the UI as a property of the preset patterns.

Exported pptx with newly set 0 line spacing

If I try to set a 0 line spacing in a current LO version, the exported line spacing value is set to 0.05 cm and not a solid fill anymore.

Exported pptx with newly set 0 line spacing in PP and Impress

LO no longer saves 0 line spacing to pptx, so it's not possible to export the solid fill instead of hatching.

Addition: the original file can still be exported with solid fill, but any newly created hatching with 0 line spacing cannot.

Maybe we can live with that, and close this as WFM?
