Reading through the license of a commercial font I'm interested in,
I see it stipulated for PDF files created that:
"... a reader or user cannot create new content using one of our
fonts in a PDF application ... the complete font is not embedded"
And in an email correspondence with the vendor:
"We just ask that you subset the font when exporting the PDFs ..."
Do PDF's generated by XeTeX and LuaTeX "subset the font" in this way?
Regards,
John

Yes, this is the default. So unless you have manually interfered, the included fonts are always subsetted.

Some of the other tables are also stripped down (not only the 'glyf' table), so that the embedded font is not complete. In fact, some programs will refuse to open the font if we extract it from the PDF, which is precisely the idea of a subsetted font (you can't use the PDF to retrieve the font).

I wonder about these webfonts .. the whole model is based on good will and no abuse .. it's a comparable issue.

I'm interested in the other way around, how can I tell luatex (or context) to not subset the font, and I read that some recent version of PDF specification allow embedding of unchanged opentype fonts (as compared to converting them to type1 fonts), does luatex support (or plan to support) that feature?

In LuaTeX, we are not converting to Type1, OpenType fonts are always embedded as CID Type0C, Truetype as CID TrueType. But some OT tables are stripped for efficiency reasons (GSUB and GPOS, for example).

I can't tell a difference :) I'm just interested in being able to extract the full font from PDF with all tables and stuff (they are my fonts, so the legal side is sorted out), but I don't actually have a use case for that :) Regards, Khaled -- Khaled Hosny Arabic localiser and member of Arabeyes.org team Free font developer ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 9+ messages in thread
