The core directory for the impress/draw applications.
|
|
|
|
Think of impress as a hack on top of draw.
|
|
|
|
|
|
sd module contains impress/draw specific code, non-shared UI and part
|
|
of ppt and pptx filter, few other filters too.
|
|
|
|
the slideshow UI lives here as well, the slideshow engine is in
|
|
slideshow module though (including the 3D transitions engine
|
|
slideshow/source/engine/OGLTrans).
|
|
|
|
the most used filters are ODF's odp, binary ppt and OOXML's
|
|
pptx. their locations are listed below:
|
|
|
|
* odp import and export filters are in xmloff module (mostly xmloff/source/draw)
|
|
|
|
* ppt import is in sd/source/filter/ppt (big shared chunks are also in svx)
|
|
* ppt export is in sd/source/filter/eppt (big shared chunks are also in svx)
|
|
|
|
* pptx import is in oox/source/ppt (and uses a lot of
|
|
oox/source/drawingml and oox/source/*)
|
|
* pptx export is in sd/source/filter/eppt (mostly in pptx-* source
|
|
files) and shared part is in oox/source/export
|
|
|
|
== PPTX export/import filters ==
|
|
|
|
PPTX export filter is split into 2 parts. Impress related part is in
|
|
sd/source/filter/eppt/pptx-* and the other part is in
|
|
oox/source/export/ because it contains mostly code related to
|
|
DrawingML, which is shared with writer and calc ooxml export.
|
|
|
|
The export filter was written in 2009 IIRC and was not much extended
|
|
feature-wise lately.
|
|
|
|
FUTURE work: add custom shapes export (see below). enhance text
|
|
output, we don't write text style for indentation levels now, need to
|
|
export a:lvl1pPr, a:lvl2pPr, ... elements.
|
|
|
|
PPTX import was written by Sun/Oracle and then extended in LibreOffice
|
|
a lot during bug fixing. It is located in oox/source/ppt and
|
|
oox/source/drawingml. The areas with most bugs (at least until today)
|
|
were shape placeholders and text style inheritance.
