Tomaž Vajngerl 8c2f779a93 sd: hide text boundaries for PDF in Draw
A PDF opened in Draw fills every page with a single imported image,
so the text boundary guides carry no meaning there. Drawing the page
background as transparent recently let those guides show through,
where the opaque background used to hide them.

Skip the guides whenever the document is a PDF, no matter what the
"show boundary for margins" setting says. Ordinary Draw documents
still follow the setting. The flag is recomputed on every redraw in
DrawView::CompleteRedraw, so the PDF exclusion goes there.

Add a test that renders a PDF page and checks the inner page border
is not drawn in the boundary color.

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:

  • 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.

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.
