[xep-support] Lots of embedded font subsets

[Alexander Peshkov]

Hello Brett,

When embedding PDF as an image XEP drops some PDF objects which cannot
be used in a resulting PDF, but fonts is a critical part and XEP
cannot be told to drop them. Note also that all font subsets are
unique and as far as I know Acrobat itself cannot make single subset
out of them while joining several PDFs.
What you should do in my opinion is configure application that
produce those PDF images so that it makes PDFs with non-embedded
fonts. Even if those fonts won't be available in the final document
you'll be OK since Acrobat will substitute them with default fonts
(and you said it's fine for you). In this case the font redundancy
will go away.

Best regards,

BK> Hello -

BK> I'm currently investigating XEP as a FrameMaker replacement in a highly 
automated DocBook ->> PDF workflow, and so far I'm quite impressed.  We 
BK> produce large documents (hundreds and sometimes thousands of pages), 
BK> some of which have many embedded PDF graphics (up to ~10,000 images).  
BK> Here's one issue I'm running into:

BK> An automated system produces the embedded PDF images, and when it does, 
BK> it embeds and subsets the fonts used in the graphics.  All of the 
BK> graphics use the same four or five fonts.  When XEP produces the final 
BK> PDF document, with the embedded images, it contains tens of thousands 
BK> of embedded, subsetted fonts, which end up taking up huge amounts of 
BK> space in the file.

BK> Question - I've read that XEP drops certain elements from PDF files 
BK> when it embeds them - like annotations, javascript, etc.  Is there any 
BK> way to tell XEP to also drop font information as well?  I can live with 
BK> the graphics using the 'Adobe Base 14' fonts if necessary.  I've read 
BK> in other responses that the embedded PDFs won't have access to any 
BK> other fonts in the document, so I'm assuming that is the price I'd pay 
BK> for removing the embedded fonts.

BK> Any other thoughts on a workaround to this issue would be greatly 
BK> appreciated.
