CIDFont and PDF

forums_noreply@adobe.com — Tue, 11 Nov 2014 14:20:43 GMT

Hi,

thanks to the lrosenth for the help with my question about support for CID keyed Type1 fonts in PDF.

I will make sure that I read the ISO PDF spec - it is more clear.

Sadly, I have another question:

I have a valid CIDFont (consists of a readable PS part and also binary data which I believe is _parts_ of a CFF font program, not the whole program).

The readable PS part has info like byte offsets to CharStrings and also the table that maps CID values to font/glyph (CIDMap)

The FreeType library will render glyphs from this font.

The binary parts appear to be the CIDMap and CharStrings etc - but not the usual CFF header stuff - ie. just the bits you need.

My question: Am I right that you cant put such a CIDFont in a PDF file as an embedded font program (as part of a composite CIDFontType0) ?

From my reading of the spec, a composite font (Type0) in PDF references a CIDFont dict that doesn't have any of the info that the PS CIDFont contains (such as byte offsets to charstring data etc)

and so it needs the complete CFF program - specified as /FontFile3 in the font descriptor.

Hi,

I understand that PDF supports embedded CFF font programs for composite fonts of type CIDFontType0 - the spec is clear.

But, does it support embedded font programs that are not CFF - ie. CIDFont with type 1 descendent for example?

The spec only mentions CFF when talking about type 1 composite fonts, but it isn't totally clear.

So, does PDF support embedded non-CFF programs for composite type 1 fonts?

regards

Steve
