Miklos Vajna 7d56dae337 tdf#127236 vcl: fix missing encryption of PDF images during export
Regression from commit 78e25558e8
(tdf#106059 PDF export: create a reference XObject for JPG images with
PDF data, 2017-02-23), once a PDF image was inserted to a document, an
encrypted PDF export lost those images.

The reason for this is that we started to preserve PDF images as vector
data with the above commit, but this means we copied over PDF objects
from PDF images to the export result as-is, so encryption was not
performed for them.

Fix this by separating the write of the PDF object headers, stream
content and object footer and then calling
checkAndEnableStreamEncryption() / disableStreamEncryption() for each
object, even if it's not something our PDF export created but comes from
a PDF image.

Note that when existing PDF files are signed, PDF objects are also
copied into a vcl::filter::PDFDocument, but such PDF images are never
encrypted, so it's fine to have stub implementations in
vcl::filter::PDFDocument.

LibreOffice Binary

Code for the LibreOffice main binary (soffice) resides here. The soffice_main function for the soffice binary can be found here.

Stable Interface

Some of the artifacts built here are part of a LibreOffice installation set's stable interface, which (programmatic) clients can depend on. Among them are:

soffice

In the program directory (program/ on Linux and Windows, Contents/MacOS/ on macOS).

unoinfo

In the program directory (program/ on Linux and Windows, Contents/MacOS/ on macOS).

When called with a sole argument of c++, it prints to stdout an absolute pathname denoting the directory where the public URE libraries are found.

When called with a sole argument of java, it prints to stdout a marker character (either an ASCII '0' or '1') followed by a sequence of zero or more absolute pathnames denoting jars or directories that need to be included in a class loader's search locations.

If the marker character is '0' (on Linux and macOS), the pathnames are encoded as bytes, and any two pathnames in the sequence are separated from each other by NUL bytes.

If the marker character is '1' (on Windows), the pathnames are encoded as UTF-16-LE two-byte code units, and any two pathnames in the sequence are separated from each other by two-byte NUL code units.

Other Binaries

oosplash
