The document-wide link update permission is decided when the document is
loaded. But media files that the users interactively inserts should be
automatically allowed.
Remember on the media object that the user picked the reference and
allow it on its own, the same way a presentation sound the user picks is
allowed. A reference that arrived with the document still needs the
document-wide permission.

LibreOffice Impress / Draw Application
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/opengl).
the most used filters are ODF's odp, binary ppt and OOXML's
pptx. their locations are listed below:
-
odpimport and export filters are inxmloffmodule (mostlyxmloff/source/draw) -
pptimport is insd/source/filter/ppt(big shared chunks are also insvx) -
pptexport is insd/source/filter/eppt(big shared chunks are also insvx) -
pptximport is inoox/source/ppt(and uses a lot ofoox/source/drawingmlandoox/source/*) -
pptxexport is insd/source/filter/eppt(mostly inpptx-*source files) and shared part is inoox/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.
Presenter Console
The main screen uses a hardware-accelerated
canvas (e.g. cairo canvas), while the entire secondary screen
uses a VCL-canvas that is created in
sd::framework::FullScreenPane::CreateCanvas().
The secondary screen contains 3 Panes which each have
2 XWindows for the border area & the actual content,
and each content Pane is backed by a sd::presenter::PresenterCanvas
that wraps the FullScreenPane's canvas and does clipping.
Future Works
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.
