... into 3 parts: EnsureStructureElement/InitStructureElement/BeginStructureElement So EnsureStructureElement and BeginStructureElement/EndStructureElement can be called multiple times for the same object, passing in a unique key and PDFExtOutDevData will only create the element once. InitStructureElement will be used exactly once for each object when its actual content is exported. In PDFExtOutDevData rely on the indexes being the same here and in PDFWriterImpl, because then only PDFExtOutDevData needs to maintain the map from key to index.

LibreOffice Filters
Filter registration and some simple filters (also descriptions).
Desperate splitting of code into small shared libraries for historical
reasons presumably (OS/2 and Windows 3.x). The libraries produced from
the code in each subdirectory of filter/source/graphicfilter are
graphic format import or export filters. But they don't have uniform
API. Some have either a GraphicImport or GraphicExport entry point,
and are loaded and used in a uniform fashion from code in
svtools/source/filter/filter.cxx. Others have different API and are
loaded from other places. For instance icgm has ImportCGM, and is
loaded and used by sd/source/filter/cgm/sdcgmfilter.cxx (!).
Svgreader is used for "File -> Open" and then to choose the svg file.
For "Insert -> Picture -> From File", see svgio/source/svgreader directory.
Filter Configuration
The filter configuration consists of two parts, the type definition in
filter/source/config/fragments/types/ and the actual filter definition
in filter/source/config/fragments/filters/.
Each file type e.g. text file should be represented by exactly one type definition. This type can then be referenced by several different filters, e.g. calc text, writer text.
