Description Aron Budea 2018-02-10 01:57:43 UTC
Created attachment 139748 [details]
Sample PPTX

Open, save and reopen the attached PPTX having a triangle shape.

=> Triangle is shifted down.

In ppt/slides/slide1.xml, the values change upon save as follows:

<a:xfrm rot="10800000" flipH="1">
  <a:off x="1892386" y="1683327"/>
  <a:ext cx="1983423" cy="1652153"/>

<a:xfrm flipH="1" rot="10800000">
  <a:off x="2307600" y="3166560"/>
  <a:ext cx="247320" cy="83880"/>

Observed using LO / Windows 7.
In the result was worse: the shape is also shifted horizontally.

The horizontal shift got fixed by the following commit:

PPTX export: correct position of rotated groups
Comment 1 Jacques Guilleron 2018-02-10 13:46:47 UTC
Hi Aron,

I confirm this shifting with
LO Build ID: 64a0f66915f38c6217de274f0aa8e15618924765
Threads CPU : 2; OS : Windows 6.1; UI Render : par défaut; 
Locale : fr-FR (fr_FR); Calc: CL
with these values when saved:

-<a:xfrm rot="10800000" flipH="1">
<a:off y="3335400" x="1891800"/>
<a:ext cy="1651680" cx="1983240"/>
Comment 2 Jacques Guilleron 2018-02-10 14:14:19 UTC
This shifting occurs also with
LO Version ID : 235ab8a-3802056-4a8fed3-2d66ea8-e241b80
under Windows 7, so probably inherited from OOo.
Comment 3 Aron Budea 2018-09-09 21:29:07 UTC
Turns out this got fixed by the same commit as bug 91999, setting as duplicate.
