nGroupShapeBooleanProperties contains 16 shape properties and 16 flags to indicate whether they are to be used or not. Up till now, only fLayoutInCell has been used by LO, but it handles far more than that, so lets change the code (now that we have the documentation for it) to make it clear that this could be useful for further compatibility fixes. There is no need to determine whether the setting has been provided or not - since a zero default indicates everything in this bit-set should be ignored. The naming and the if clause in ww8graf.cxx suggests that reverse engineering didn't really grasp how this worked, so I took the liberty of removing all of that awkwardness, and verified that at least several associated document from the OOo Apache bugtracker still worked. =============================================================== https://docs.microsoft.com/en-us/openspecs/office_file_formats /ms-odraw/a0ae6aa5-16e4-4550-87a2-b8ca180c7fd7 fLayoutInCell (1 bit): A bit that specifies whether this shape is displayed inside a table cell. If fUsefLayoutInCell equals 0x0, this value MUST be ignored. The default value for this property is 0x1.

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.
