2. TERMINOLOGY

3. 3
FREE SOFTWARE
●
The term Free Software was created in 1986 by Richard M. Stallman.
●
Free Software refers to freedom, not price.
●
It guarantees its users the essential four freedoms.
●
The absence of at least one of these freedoms means an application is
proprietary, so non free software

4. 4
THE FOUR FREEDOMS

5. 5
THE CAMPAIGN

6. 6
LIBREOFFICE - DOUBLE MEANING
●
LibreOffice is
1. the leading free office productivity suite
installed by millions of users worldwide
2. a wonderful worldwide community
with hundreds of friends, contributors and companies around the globe
●
The Document Foundation (TDF) as legal entity is
– a nonprofit ”Stiftung” (foundation) based in Berlin
”The objective of the foundation is the promotion and development
of office software available for use by anyone free of charge”
– does not contain a product name on purpose

7. A LARGE NUMBER OF CONTRIBUTORS AND USERS...

8. ...THAT ASK ALSO FOR PROFESSIONAL SUPPORT

3087011E2EB810866276E270A6FC61A7E0998FEC
●
Replacement of LibreOffice SVG filter in favour of SVGIO
●
Two different import Filters (historically grown)
●
Difference between insert/open SVG
●
Varying quality with no explanation → not acceptable
●
More info available: Armin held a presentation at last
year‘s LibreOffice Conference in Tirana about that

ROTATEFLYFRAME(1|2|3)
FREELY ROTATABLE FLY FRAMES IN
LIBREOFFICE WRITER
●
FlyFrames could only be rotated in 90-degree steps
(historical reasons, but workarounds)
●
Question of functionality/comfort, but also compatibility
●
Huge change/effort needed to isolate and securely manipulate old structures
●
More info available: Armin held a presentation about that at FOSDEM‘18 in
Brussels

Text input massively slow
●
Solution: Move EditEngine visualization to Overlay during active TextEdit
