2. Enter presentation mode.
3. Observe how "Rancher by SUSE" hardly is visible any longer.

The missing logo is covered by bug #156902.

But the first RANCHER is not text but free forms.

Reproducible with

tdf#126319 Corrected bitmap creation from metafile

Comment 6 Armin Le Grand (allotropia) 2023-09-12 11:46:47 UTC
1st note: Text is a group object, as a workarund un-grouping it makes it appear.

Reduced bugdoc

Also happens with reduced bugdoc - only the group object remains. The original had quite some objects, nearly invisible, below the BG graphic.
Comment 8 Armin Le Grand (allotropia) 2023-09-12 12:09:38 UTC
Looked at the bibisect from comment 5 (thanks!), but that seems the wrong trace. What I found is that the group object created from PPTX import contains 9 objects where 'BY SUSE' is a group itself where 'BY' is a group with 2 FreeForm objects (the letters) an 'SUSE' is a single freeform. All objjects are freeforms, BUT
the group contains an invisible shape (use TAB to select) that has size(0,0) and pos(0,0) and all attr on default (fill blue, ...).

If this shape is deleted, all works fine.

It could be that this empty shape 'irritates' the conversion for SlideSHow somehow, but I e.g. get no BP hit @GraphicExporter::GetGraphic that I would normally get (and where the changes of the mentioned change are).
Comment 9 Armin Le Grand (allotropia) 2023-09-12 13:18:56 UTC
Ah - I see. That shape at (0,0) size (0,0) *is* the missing logo. Thus this task will be fixed when that is fixed (bug #156902).

The BoundRect includes that shape, so (0,0,w,h) is displayed @the coordinates without hat shape -> smaller visualization, what we see.

I could try to find out and fix that a shape with that dimensions/missing logo is imported, but that may then collide with the fix for bug #156902.

There is definitely a difference between BoundRect(old) and BoundRange(new) based on primitives, though: the 2nd one includes those shapes - what is in principle more correct.
Comment 10 Armin Le Grand (allotropia) 2023-09-12 13:55:56 UTC
Checked for getB2DRange, but as I thought: It's an object at (0,0) with size(0,0). To *not* merge it when using getB2DRange would be wrong. This task just needs fixing of task bug #156902.
Comment 11 Gabor Kelemen (allotropia) 2023-10-09 14:52:46 UTC
This seems to be better since:

tdf#156902 Do not set glow on group shape in import

Now both the cow shape is visible and the RANCHER text is not small in presentation mode. Remaining issue is that the cow does not glow, which is a missing feature (bug 157661 now).

Maybe we can refocus this as a reminder to properly import grouped shapes' glowing effect from OOXML.
Comment 12 Gerald Pfeifer 2023-10-13 09:47:07 UTC
Let's close this, Gabor. The issue I originally reported here is 
resolved thanks to Regina, and bug #157661 tracking the missing
feature explicitly talks about PPTX and has a sample document.
