What do you think of it? ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2006-10-22 21:38 Message: Logged In: YES user_id=710 This is an update of the previous patch, which attemps to solve problem #484 as well (I would not call #484 a bug but a limitation -- a bug would mean that the behaviour is inconsistent with the specification). This patch is *very different* from the previous one, since now kerns inserted by the new primitives are treated as implicit kerns (they were treated as explicit kerns before this patch). This can lead to a very different behaviour, so be prepared :) ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2006-10-21 13:54 Message: Logged In: YES user_id=421 Thanks! Any idea for 484? :-) ---------------------------------------------------------------------- You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=495&aid=663&group_id=106

[ pdftex-Bugs-304 ] Names of expanded fonts not in log output

MM fonts are probably the only case where one would not want to use the autoexpand feature. At first sight, saying "autoexpand" or not doesn't seem to make a difference, since pdftex will always prefer existing expanded fonts (pfb) over autoexpanding them, anyway. However, there are some slight differences in the pdf. This is probably because the provided tfm file is different from the metrics that pdf calculates itself in the case of autoexpand. That is, autoexpand may result in a mismatch between the provided pfb and the calculated tfm, is that correct? ---------------------------------------------------------------------- Comment By: Hartmut Henkel (hhenkel) Date: 2006-09-01 21:02 Message: Logged In: YES user_id=929 currently i even can't get a test file do expansion at all without "autoexpand". E. g. Robert's example above, without "autoexpand", doesn't use expanded fonts. Maybe that's the reason for the missing expand parameter in the log? Can anybody provide a test file for this case? Regards, Hartmut ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2006-09-01 12:47 Message: Logged In: YES user_id=421 Is this really a problem, i.e. is there a reason _not_ to use the autoexpand feature in new documents? Hartmut, did you look into this bug? ---------------------------------------------------------------------- Comment By: Robert (schlcht) Date: 2005-10-16 00:24 Message: Logged In: YES user_id=2217 If the font is not autoexpand'ed, its name will still not be written to the log file. (pdftex 1.30.3; same test file, without "autoexpand") Regards, Robert. ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2005-05-12 17:05 Message: Logged In: YES user_id=421 This has been fixed in 1.30.0 ---------------------------------------------------------------------- Comment By: Hartmut Henkel (hhenkel) Date: 2005-03-30 22:16 Message: Logged In: YES user_id=929 This patch is based of Thanh's change file showfont.ch, which he gave me during EuroTeX2005 (it's also included, renamed here to showfont-thanh.ch). Use showfont.ch for the patch. There is now a new integer variable \pdftracingfonts. It is zero by default, then we get a log like this (see robert050302.log): ...\tenrm t ...\tenrm (+20) e Without font expansion, this default should be compatible with TeX's original log output. If \pdftracingfonts is set to 1 (or greater), we get a more verbose log (see tst-304.log): ...\xivtt (cmtt10(a)14.0pt) t .\xivtt (cmtt10+20(a)14.0pt) e Seems to work with change file showfont.ch coming directly after after hz.ch. Patch only roughly tested with pdfetex, likely to give problems with pdfxtex, as the variable numbering might differ. Log format to be agreed upon...

[ pdftex-Bugs-606 ] Forbidden ... while scanning ???

Bugs item #606, was opened at 2006-09-16 22:28 You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=493&aid=606&group_id=106 Category: Primitives Group: v1.40.0 Status: Open >Resolution: Postponed Priority: 3 Submitted By: Hartmut Henkel (hhenkel) Assigned to: Hartmut Henkel (hhenkel) Summary: Forbidden ... while scanning ??? Initial Comment: \pdftrailer {abc \bye gives ! Forbidden control sequence found while scanning text of \pdftrailer. but \pdfximage {abc \bye or \pdfliteral {abc \bye give ! Forbidden control sequence found while scanning text of ???. Instead of these three question marks there should be the name of the primitive. ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2006-09-21 14:22 Message: Logged In: YES user_id=421 I've backed out the change; this is low priority and probably needs more changes. ---------------------------------------------------------------------- Comment By: Hartmut Henkel (hhenkel) Date: 2006-09-17 21:10 Message: Logged In: YES user_id=929 yes, the patch works, thanks a lot! But there are in fact many more \pdf... primitives that suffer from this problem, actually any with a scan_keyword call before the scan_pdf_ext_toks. After the way how it's done in @<Implement \.{\write}@>=, it seems that a new variable save_cur_cs is not needed if one uses k for this purpose. Needs change of a few k uses to j. But problematic is \pdfoutline as it has another scan_pdf_ext_toks for the attr keyword. Wouldn't these many changes be too risky for 1.40.0? ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2006-09-17 18:34 Message: Logged In: YES user_id=421 The patch was missing. Fixed. ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2006-09-17 16:30 Message: Logged In: YES user_id=421 The cause seems to be that some scan_functions loose the meaning of cur_cs, which leads to the ??? when reaching <Tell the user what has run away...@>. The attached (IMHO crude) patch fixes this for the cases you mentioned, but there are probably other cases not found... ---------------------------------------------------------------------- You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=493&aid=606&group_id=106
