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.

Spreadsheet Application Code

You can dump some information in a dbgutil build:

Shortcuts

CTRL+SHIFT+F12

Dumps the column width of the first 20 columns.

CTRL+SHIFT+F11

Dumps the graphic objects and their position and size in pixel.

CTRL+SHIFT+F6

Dumps the SfxItemSet representing the cell properties' of the current selection as a xml file. The file will be named dump.xml

The Cache Format

ScDocument::StoreTabToCache allows storing the content (not the formatting) of a table to a binary cache format.

The format is column orientated which allows quick serialization of the table.

  • Header:

    • Number of Columns: 64 bit unsigned integer

  • Column:

    • Column Index: 64 bit unsigned integer
    • Column Size: 64 bit unsigned integer
    • For each cell type block a new ColumnBlock

  • ColumnBlock:

    • Start Row: 64 bit unsigned integer
    • Block Size: 64 bit unsigned integer
    • Type: 8 bit unsigned integer
      • 0 : empty
      • 1 : numeric
        • for each cell: 64 bit IEEE 754 double precision value
      • 2 : string
        • for each cell: 32 bit signed string length followed by string length bytes of the string (UTF-8)
      • 3 : formula
        • for each cell: 32 bit signed string length followed by the formula in R1C1 notation as a string

Functions Supporting Wildcards or Regular Expressions

As this comes up every now and then, and rather should be documented in an extra list of the Help system, functions that support Wildcards or Regular Expressions and depend on the setting under Tools -> Options -> Calc -> Calculate are those that in ODF OpenFormula (ODFF) are defined to depend on the HOST-USE-REGULAR-EXPRESSIONS or HOST-USE-WILDCARDS properties, see https://docs.oasis-open.org/office/v1.2/os/OpenDocument-v1.2-os-part2.html
