Description olo 2005-03-30 15:07:02 UTC

This has been tested with OpenOffice versions: 1.1.4 and 1.97.87 (680m87
snapshot build) on Mandrake Linux 10.2 (development version - "cooker") and
Fedora Core 3 Linux.

Builtin PDF export in OpenOffice fails to subset Type1 fonts (but succeeds with
TrueType), and instead embeds full fonts in PDF files.

With some Unicode fonts, which contain lots of glyphs for various alphabets (e.g
Nimbus Sans L, Nimbus Roman No9 L), this inflates the size of resulting PDF
files up to hundreds of KB, even for small text-only documents!

I've gathered some testcases here:

And the whole issue has been recently discussed by many users on OOOforum:

Contrary to what has been said in issue 20370, Type 1 fonts are definitely
subsettable - e.g. Ghostscript subsets both TrueType and type 1 when generating
PDFs, and you can see an example of a PDF with subsetted Type 1 and TrueType
fonts here (Ghostscript was the generator):

A workaround is to print to PostScript and use a converter (e.g. ps2pdf) to
generate PDF files. There is an excellent OpenOffice macro library that adds a
GUI for this operation: it's called extendedPDF, available here:

However, having OpenOffice generate nice PDFs natively would be certainly much
better. Even setting up extendedPDF requires some plumbing experience and is
definitely not for majority of users...

->pl: you or hdu ?

Type1 fonts are not subsettable for OOo at the moment since we simpy don't have
code that can do that. BTW the same is true for OOo's PostScript output.

Changing type to enhancement, target to later
