Bug ID: 86020
Summary: OOXML: not importing un-documented PPT / binary XML
records for characters spacing
Product: LibreOffice
Version: Inherited From OOo
Hardware: Other
OS: All
Status: UNCONFIRMED
Severity: enhancement
Priority: medium
Component: Presentation
Assignee: [email protected]

bugdoc (PPT)
Open the attached .ppt file. In page 3, all of the character spacing
information is missing. The problem here is that we don't import the expanded /
condensed state.
Running our ppt dumper tool on two variants of a minimal sample document, with
and without character spacing applied in PowerPoint 2013, it is evident that
the character spacing is implemented through the use of embedded OOXML in the
.ppt. This is a feature of newer .ppt variants (since MSO 2007) and something
that as far as I can see OpenOffice.org and LibreOffice does not support.
The ppt dumper displays for a trivial document with a "very tight" character
spacing:

where the spc="-300" presumably corresponds to the "very tight" character
spacing. In an otherwise identical document with no character spacing applied,
this whole embedded OOXML-ish record is not present.
Possibly the MS symbolic name for the 0xf122 is OfficeArtTertiaryFOPT, defined
in http://msdn.microsoft.com/en-us/library/dd950206(v=office.12).aspx , part of
something called "Office Drawing Binary Format", which can be includes also in
PPT, as said on
http://msdn.microsoft.com/en-us/library/dd910075(v=office.12).aspx . But I
haven't been able to find any documentation for this embedded OOXML stuff.
