src special
by The Thanh Han 28 Nov '04

28 Nov '04

Hi, the pdfsync' folks are asking for something similar to the src special extension, but for use with pdf. I asked for Olaf's opinions, and got the following answer: > I got the implementation from elsewhere, and IIRC indirectly. In > other words, I'm not completely certain at this point where it came > from and who wrote it. > > By the way, do bear in mind that the implementation is buggy (and > pretty much intrinsically so without a lot of work): there are cases > where enabling source specials will change the layout of a document. so it looks that following this trace can introduce new problems. I would like to learn more about this issue -- does anyone has some ideas how it should be implemented? Thanh

Re: Question on 1.20b-rc0 font replacement
by The Thanh Han 26 Nov '04

26 Nov '04

Hi, thanks to Hartmut for discovering the bizard case. There is some test in pdftoepdf.cc, so the font is still copied. But lookup_ps_fontmap when found a matched entry also created a new internal font, so the font is still embedded (but is not used anywhere). Here is the new mapfile.c Regards, Thanh On Fri, Nov 26, 2004 at 01:08:06AM +0100, Hartmut Henkel wrote: > shouldn't it then be for safety: > > > /* search forward */ > do { > ff = check_ff_exist(p); > if (ff->ff_path != NULL && !is_truetype(p) && used_tfm(p)) > ^^^^^^^^^^^^^^^ > > Regards, Hartmut > > > On Fri, 26 Nov 2004, Hartmut Henkel wrote: > > > just a question about replacement of Type1 fontsfrom included ximages: > > > > If the mapline by accident contains a TTF font file (e. g. > > <ptmr8a.ttf), with matching PS name, what would happen?

1.20b-rc0 font replacement bug
by Hartmut Henkel 26 Nov '04

26 Nov '04

Hi Thanh, when a PDF file with embedded fonts is included by \pdfximage, fonts will be replaced through lookup_ps_name() heuristics. However it's actually not checked there whether the font file itself is available. Problem example: Some PDF file comes with a Palatino-Roman. TFM entry pplr8r is listed in the mapfile together with fontfile <pplr8a.pfb. But pplr8a.pfb isn't on the PC. Still the font embedded in the PDF file will be replaced by --- nothing. One gets an invalid stream, missing letters. But if the fontfile is not available, the replacement of embedded fonts in PDF files shouldn't be done at all; instead the font coming with the PDF file should be used as is. Below is a quick patch. Only roughly checked.
