Bug ID: 146192
Summary: extrusion-viewpoint value (3472, -3472, 25000) is not
written to file, although it is not default value
Product: LibreOffice
Version: 7.4.0.0 alpha0+ Master
Hardware: x86-64 (AMD64)
URL: https://docs.oasis-open.org/office/OpenDocument/v1.3/o

attribute-draw_extrusion-viewpoint
OS: Windows (All)
Status: UNCONFIRMED
Keywords: easyHack
Severity: minor
Priority: medium
Component: Impress

The extrusion property ViewPoint uses internally the default (3472, -3472,
25000). Those values are the default values in MS Office. But ODF has the
default value (3.5cm -3.5cm 25cm). Therefore (3472, -3472, 25000) needs to be
written to file, e.g. as (3.472cm -3.472cm 25cm). When then - after some years
- the existing files have this value, the import can be changed to interpret a
missing value as (3500, -3500, 25000).
Workaround: Use a different direction and then switch back to the default
direction "Extrusion South-West". Now the value is explicitly set and is
written to file
Because the difference is not large and a workaround exists, the Severity is
minor.
To reproduce it: Start Impress and insert a custom shape, e.g. "Diamond".
Toggle it to "Extrusion on". Click "Perspective" in drop-down "Direction" in
toolbar "3D-Settings". Save the file in Open Document Format. Inspect the file.
You should find an attribute draw:extrusion-viewpoint, but such attribute is
missing.
This is similar to bug 141301 and can be handled the same way.
