Bug ID: 156717
Summary: Add minor version / OS to PDF producer metada
Product: LibreOffice
Version: 24.2.0.0 alpha0+ Master
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: LibreOffice
Assignee: [email protected]
Reporter: [email protected]
Description:
For diagnostic purposes, it is very useful to know the exact minor version of
the LibreOffice used to produce the PDF. This can be added to the "PDF
Producer" metadata.
This metadata can be shown in almost any PDF viewer.
For example, instead of:
LibreOffice 7.5
It should be something like:
LibreOffice 7.5.3.2 (X86_64) / LibreOffice Community
For development versions, it would be something like:
LibreOfficeDev 24.2.0.0.alpha0+ (X86_64) / LibreOffice Community
It would be good to even have the localized version of this text.
Code pointers:
If you look into filter/source/pdf/pdfexport.cxx, you will see that in
PDFExport::Export(), aContext.DocumentInfo.Creator is set. You can change it to
a new text, and see it in action, by setting:
aContext.DocumentInfo.Creator = "Hello world!";
And then exporting a file to PDF, looking into the metadata.
On the other hand, if you go to Help > About, you will see the same string is
visible in the "About" dialog. If you look at cui/source/dialogs/about.cxx, you
will see GetVersionString(), which provides the above (localized) string.
Combining these two, one can implement this feature.
