Follow-up improvement to commit 3eb9eb9906 (lok: add pdf version
option for export, 2021-11-15), possibilities are endless.
For example, to skip the first page of a Draw document:
soffice --convert-to 'pdf:draw_pdf_Export:{"PageRange":{"type":"string","value":"2-"}}' test.odg
Add watermark:
soffice --convert-to 'pdf:draw_pdf_Export:{"TiledWatermark":{"type":"string","value":"draft"}}' test.odg
Encrypt:
soffice --convert-to 'pdf:draw_pdf_Export:{"EncryptFile":{"type":"boolean","value":"true"},"DocumentOpenPassword":{"type":"string","value":"secret"}}' test.odg
Version 1.5 (instead of the default 1.6):
soffice --convert-to 'pdf:draw_pdf_Export:{"SelectPdfVersion":{"type":"long","value":"15"}}' test.odg
The cost of the verbose syntax is probably smaller than the benefit of
having this 1:1 mapping from string to PropertyValues.

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.
