Description Philipp Petschner 2017-04-24 07:39:52 UTC
Description:
There are the same problems when using the Libreoffice program or Libreoffice as command line. Libreoffice displays false previews in the sidebar on the left. This is the same false preview as the command line conversion to pdf does. For example: gradient from powerpoint is not shown, headers / logos are not visible at all.

Steps to Reproduce:
1.open the pptx file and compare it to powerpoint (false preview is shown in the left sidebar.
2.use libreoffice as command line and convert the pptx file to pdf

soffice.exe --headless --convert-to pdf originalFileRef

(or open the file with libreoffice and take a look at the previews in the left sidebar)

Actual Results:  
false previews: headers are missing, gradients missing, ...

Expected Results:
same result as powerpoint shows. (The headers are actually shown in the big view but not in the small preview)


Reproducible: Always

User Profile Reset: No

Additional Info:
I would be happy to send you some example files. And show you the problem in detail.

Tried bibisecting on Linux with 43all, but unfortunately ran into a lot of
terminate called after throwing an instance of 'com::sun::star::uno::DeploymentException'

so had to skip far too many times for the result to be useful.

The problem is between last36onmaster and last35onmaster

Maybe someone wants to try and confirm if they get the launch error as well?

Urgh, never mind: https://wiki.documentfoundation.org/QA/Bibisect#Unable_to_start_soffice

I tried again and the range is https://cgit.freedesktop.org/libreoffice/core/log/?qt=range&q=c77918bb03974ff9be90c889f77e62ea0755052f...877c96a601e6e50d0c7a8f704d57baec22f089c5

Hi,

thanks for getting back to me.

The bug is still present in the current version of Libreoffice:


Version: 6.2.5.2 (x64)
Build ID: 1ec314fa52f458adc18c4f025c545a4e8b22c159
CPU threads: 8; OS: Windows 10.0; UI render: default; VCL: win; 
Locale: en-US (en_AT); UI-Language: en-US
Calc: threaded

It can be still be replicated with the original sample files and all issues appear to be the same as with older Libreoffice Versions.


best,
Philipp
