We do not need PDFDontUseFontObjectNum any longer. It's removal is not a
showstopper.
Thanks for the confirmation!

There is a method of using font non-embedded PDF.
In my experiment, it seems to work fine except

If we figure out a working alternative, we should take it. The current

clear yet which alternative

Its still, in my opinion, a risky thing to do. However, if the font were

There are already libraries that can read PDFs into a data structure and

Ah, you need to be careful talking about 'images'
do feel that creating the pages in this fashion is less than ideal and
you would probably be well advised to seek a different way of working.
As I have said (repeatedly now) I will discuss this with the other
developers, and the input (especially from Knut's mail) will be taken into
