View module in: git
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
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
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
ppt import is in
sd/source/filter/ppt (big shared chunks are also in
ppt export is in
sd/source/filter/eppt (big shared chunks are also in
pptx import is in
oox/source/ppt (and uses a lot of
pptxexport is in
pptx-*source files) and shared part is in
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.
Add custom shapes export (see below). enhance text
output, we don’t write text style for indentation levels now, need to
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/drawingml. The areas with most bugs (at least until today)
were shape placeholders and text style inheritance.
