Bugs item #747, was opened at 2007-03-09 04:09 You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=493&aid=747&group_id=106 Category: hz Group: v1.40.1 Status: Open Resolution: Accepted Priority: 5 Submitted By: Robert (schlcht) Assigned to: The Thanh Han (hanthethanh) Summary: \letterspacefont and \pdffontexpand, again Initial Comment: When expanding a letterspaced font, the base font will be expanded, too, resulting in the error `font has been expanded with different parameters' when the base font is expanded again: \letterspacefont\lsfont\font 100 \pdffontexpand\lsfont 20 20 5 autoexpand \pdffontexpand\font 20 20 5 autoexpand Z\bye ---------------------------------------------------------------------- >Comment By: Martin Schröder (oneiros) Date: 2007-07-08 19:17 Message: Logged In: YES user_id=421 The patch had one rejected hunk against stable and current. A working patch is attached; please check. ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2007-07-04 10:13 Message: Logged In: YES user_id=710 patch updated again. Disable \pdfcopyfont for expanded and letterspaced fonts. ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2007-07-03 23:21 Message: Logged In: YES user_id=710 I didn't consider the situation when an expanded font is copied. It seems pretty much of work is needed to get it right, so probably it is easier to disable \pdfcopyfont for expanded (and letterspaced) fonts. ---------------------------------------------------------------------- Comment By: Robert (schlcht) Date: 2007-07-03 19:39 Message: Logged In: YES user_id=2217 Thanks. Letterspacing+expansion works fine now, and \pdfcopyfont is also useful. I gather an expanded font cannot be copied again, right? (Not that I would deem this necessary.) The messages from the following are a bit weird: \tracingonline1 \font\f=cmr10 \pdfcopyfont\fA\f \pdffontexpand\fA 10 10 5 autoexpand \fA ABC \pdfcopyfont\fB\fA \fB ABC \bye ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2007-06-30 18:25 Message: Logged In: YES user_id=710 ah, sorry, here it is. ---------------------------------------------------------------------- Comment By: Robert (schlcht) Date: 2007-06-30 18:12 Message: Logged In: YES user_id=2217 the patch is missing... ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2007-06-29 17:58 Message: Logged In: YES user_id=710 patch updated again. I have tested it with the following: \font\f=cmr10 \pdfcopyfont\fA=\f \letterspacefont\fB=\fA 100 \pdffontexpand\fB 30 30 5 autoexpand \fB \input tufte.tex and it seems to work. But the following doesn't: \letterspacefont\fC=\f 100 \pdfcopyfont\fD=\fC \pdffontexpand\fD 30 30 5 autoexpand probably it's possible with some more effort to make the latter case work too, but it doesn't seem needed. ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2007-06-29 15:32 Message: Logged In: YES user_id=710 patch deleted. Needs more testing. ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2007-06-29 11:56 Message: Logged In: YES user_id=710 sorry, I didn't test it carefully enough. Here is another attempt (tested with the microtype manual). ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2007-06-29 10:52 Message: Logged In: YES user_id=421 Taco, the new_font_type -> real_font_type is from the fix for bug #722. We need an svn... :-( ---------------------------------------------------------------------- Comment By: Taco Hoekwater (taco) Date: 2007-06-29 09:22 Message: Logged In: YES user_id=1608 On my (fairly) clean sources, one hunk is rejected because of this: else begin if pdf_font_type[f] <> new_font_type then pdf_warning("font expansion", "font should be expanded before its first use", true, true); end; My pdftex.web uses pdf_font_type[f] = real_font_type in that test. I fixed the hunk, but I also get a crash on Robert's test file. ---------------------------------------------------------------------- Comment By: Robert (schlcht) Date: 2007-06-29 01:17 Message: Logged In: YES user_id=2217 Now this yields a core dump with: \pdfadjustspacing2 \pdffontexpand\font 20 20 5 autoexpand \hsize10em Lorem ipsum dolor sit amet, \bye (unless I've messed up pdftex.web with all them patches) ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2007-06-28 22:17 Message: Logged In: YES user_id=710 here is another patch, which introduces \pdfcopyfont. Example: \letterspacefont\lsfont\font 100 \pdfcopyfont\lsxfont\lsfont \pdffontexpand\lsxfont 20 20 5 autoexpand This patch also fixed a bug in expanding local font from virtual fonts: font shrinking didn't work. Big thanks to Robert for help with testing. ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2007-06-28 20:42 Message: Logged In: YES user_id=710 expanding a letterspaced fonts always implies that the base font is expanded. In other words, it's impossible *not* to expand the base font when expanding a letterspaced font. thanks for further testing. It looks like a bug in checking font expansion spec. fwiw, font stretch limit is always fixed to [0..1000] and font shrink limit to [0..500]. Thus giving a negative value has the same effect like giving 0. I will play with \copyfont to see if it helps. ---------------------------------------------------------------------- Comment By: Robert (schlcht) Date: 2007-06-28 16:01 Message: Logged In: YES user_id=2217 If we can get rid of the error message, I think it can be left at that. Mind you, the problem is not how to expand a letterspaced font but how to *not* expand the base font when expanding a letterspaced font. That expanding a letterspaced font results in expansion of the base font can be documented as a feature, IMO. Here are some more clues: The error message seems to be related to the sign of the stretch parameter. First of all, with \letterspacefont\lsfont\font 100 \pdffontexpand\lsfont 20 20 5 autoexpand the base font will be expanded, however it will never be shrunk. Then, \letterspacefont\lsfont\font 100 \pdffontexpand\lsfont 20 20 5 autoexpand \pdffontexpand\font 20 -20 5 autoexpand doesn't yield an error. Neither does: \pdffontexpand\lsfont 20 -20 5 autoexpand \pdffontexpand\font 20 -20 5 autoexpand However, here comes the error again: \pdffontexpand\lsfont 20 -20 5 autoexpand \pdffontexpand\font 20 20 5 autoexpand If you expand the base font first, it's OK in any case, also with different signs. ---------------------------------------------------------------------- Comment By: Taco Hoekwater (taco) Date: 2007-06-28 09:37 Message: Logged In: YES user_id=1608 That sounds nice, I like it. ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2007-06-28 08:45 Message: Logged In: YES user_id=710 I agree this is an ugly solution, which has its origin in a design mistake. However the problem here is not only how to deal with the error message, but the point is how to use font expansion with a letterspaced font. Please give it a thought so we can come up with an acceptable workaround. If we want everything to be clean, there are more things that have to be thrown away. what about this: have a primitive \copyfont which creates a copy of a font. Example: \letterspacefont\lsfont\font 100 \copyfont\lsxfont\lsfont \pdffontexpand\lsxfont 20 20 5 autoexpand ---------------------------------------------------------------------- Comment By: Taco Hoekwater (taco) Date: 2007-06-27 13:43 Message: Logged In: YES user_id=1608 If there is no clean way of solving the problem, I'd rather just document the error message as a feature. I find \pdfnewexpandfont very ugly (sorry Thanh). ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2007-06-24 12:46 Message: Logged In: YES user_id=710 here is a patch that introduces a new primitive \pdfnewexpandfont. Usage: \font\f=cmr10 \pdfnewexpandfont\fx \f 20 20 5 autoexpand Note that \pdfnewexpandfont generates \fx by loading a TFM corresponding to \f first, then applies font expansion in the same way like "\pdffontexpand\fx 20 20 5". So when \f is a font that doesn't have a corresponding TFM (for example, because it was generated in pdftex memory only), the above command won't work. In particular, the following doesn't work: \font\f=cmr10 \letterspacefont\lsfont\f 100 \pdfnewexpandfont\fx \lsfont 20 20 5 autoexpand since \lsfont doesn't have a corresponding TFM but was generated by \letterspacefont. To create a letterspaced+expanded font, one can use: \font\f=cmr10 \letterspacefont\fx\f 100 \pdffontexpand\fx 20 20 5 autoexpand things are gettting messy... sorry about that. Testing/comments welcome. ---------------------------------------------------------------------- Comment By: Robert (schlcht) Date: 2007-04-01 02:44 Message: Logged In: YES user_id=2217 Fine for me and microtype. ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2007-03-31 11:52 Message: Logged In: YES user_id=710 either name is ok with me. We need a new pritimive to load a new font and expand it, since the current one doesn't load a new font and hence is making trouble. I would wait for a while to see how Robert sees it before making any change. ---------------------------------------------------------------------- Comment By: Nobody (None) Date: 2007-03-19 12:07 Message: Logged In: NO Hello, I do not think that \pdfexpandfont is a good name for a new primitive, as it is too easy to confuse with \pdffontexpand. What about \pdfexpandnewfont, as -- if I understand correctly -- a new font is loaded? Jonathan P.S: Thank you for creating pdfTeX! ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2007-03-10 21:18 Message: Logged In: YES user_id=710 Phil Taylor has a suggestion that seems great to me: introduce a new primitive \pdfexpandfont instead. How do you see it? ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2007-03-10 20:24 Message: Logged In: YES user_id=421 Forget that comment. Of course a change of \pdffontexpand has to be considered carefully. By you. :-) ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2007-03-10 20:22 Message: Logged In: YES user_id=421 No. It's an undocumented primitive. ;-) ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2007-03-09 18:28 Message: Logged In: YES user_id=710 sigh. A mistake when implementing the \pdffontexpand primitive: it should load a new font for expansion, instead of expanding a loaded font. Too late for change now? ---------------------------------------------------------------------- You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=493&aid=747&group_id=106

Anyway, I will change the warning to be issued for non-virtual fonts only. It turned to be a design mistake that the \pdffontexpand primitive takes a base font and turns it to an expanded font. It would be better it was more like \letterspacefont, ie it should create a new font and leave the original font intact. ---------------------------------------------------------------------- Comment By: Taco Hoekwater (taco) Date: 2007-02-02 08:30 Message: Logged In: YES user_id=1608 > I hope luatex will abolish with this nonsensical connexion of ligatures and kerns?

svn
by Martin Schröder 07 Jul '07

07 Jul '07

Hi, with the help of Fabrice Popineau we now have a public svn repository for pdfTeX. Read all about it at http://foundry.supelec.fr/scm/?group_id=23 Be warned that a full repository checkout explodes to ca. 750MB on your harddisc. All developers who might want to submit to that are requested to sign up with foundry and join the project. Also our cvs at sarovar is not used anymore; all files are also at foundry. The rest of the project (trackers etc.) is still at sarovar. Best Martin

[ pdftex-Bugs-824 ] Bus error caused by loading an image into a format file
by noreply＠sarovar.org 06 Jul '07

06 Jul '07

Bugs item #824, was opened at 2007-06-26 00:22 You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=493&aid=824&group_id=106 Category: Image inclusion Group: v1.40.3 >Status: Closed >Resolution: Fixed Priority: 5 Submitted By: Robin Houston (robinhouston) Assigned to: Martin Schröder (oneiros) Summary: Bus error caused by loading an image into a format file Initial Comment: I have written a tool that speeds up repeated compilation of a source file, by generating a format from the preamble of the document, and then using it to compile the body. One user reported a crash when using this tool with a custom letterhead class; the class in question may be found at http://www.soe.ucsc.edu/~elm/LaTeX/ucletter.cls (though note that a simpler demonstration is attached to this report). The bug is triggered by the fact that this class loads an image during the processing of the preamble (i.e. during the processing of the .ini file) and saves it in a box. When this box is used, during the compilation of the body, pdftex crashes. This does work with ordinary (non-PDF) TeX, so the problem is specific to PDFTeX. The attachment contains a simple demonstration of the problem. Unpack it and run 'make'. ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2007-07-06 22:45 Message: Logged In: YES user_id=421 A fix for this will be included in the next release (1.40.4/1.50.0). ---------------------------------------------------------------------- Comment By: Taco Hoekwater (taco) Date: 2007-07-04 12:59 Message: Logged In: YES user_id=1608 Yes, I think that does it.

In my (development version) of the source there is a state 'scheduled', that I assume comes from a fix to something else. In any case, we just have ask Martin to be extra careful about that line while creating 1.40.4 :-) It is probably wise do dump the three heads you mentioned, just in case: I really need the ximage one in my tree, and dumping the others seems a logical extension. Well done to you on finding a way around the regression. ---------------------------------------------------------------------- Comment By: Robin Houston (robinhouston) Date: 2007-07-02 13:08 Message: Logged In: YES user_id=4579 That's odd. The source I'm working from has @d is_obj_written(#) == (obj_offset(#) <> 0) Has this been changed recently? (Am I right in thinking that the development version of the source tree is not publicly available?) With regard to which linked list headers to dump, we seem to be reaching the point of making subtle improvements. The original problem (whatsit nodes in dumped boxes referencing non-existent objects) is solved without dumping any of the headers. One might conceivably want to load images/forms/raw objects in the .ini, and then reference them from the .tex: this is addressed by dumping head_tab[obj_type_ximage], head_tab[obj_type_xform] and head_tab[obj_type_obj]. (Neither forms nor raw objects have any additional associated metadata, as far as I can tell.) I can't see any benefit from dumping the other entries, whether or not doing so would cause potential crashes. At any rate, what we have now seems a definite improvement over the status quo, and avoids the undesirable feature-regression of forbidding \dump after \shipout. ---------------------------------------------------------------------- Comment By: Taco Hoekwater (taco) Date: 2007-07-02 12:53 Message: Logged In: YES user_id=1608 WRT type image object: over here, it is only included twice after I do a small fix to your patch: obj_tab[k].int2 := -1; this could just be a simple difference between my and your pdftex source trees, but please re-check. I definately have *no* runtime image with obj_tab[k].int2 := 0, and that is correct/expected, because I can see in the source that the is_obj_written() test checks for >-1. The thing with head_tab[obj_type_xform] is why I initially dumped all of them. The xforms should be safe, but fonts are definately not ok (not unless whole lot more stuff is dumped to the format). I don't know about the others heads. It depends on whether or not the objects need additional data structures besides obj_tab and pdf_mem, and I am not very much at home in that section of the pdftex code. ---------------------------------------------------------------------- Comment By: Robin Houston (robinhouston) Date: 2007-07-02 10:58 Message: Logged In: YES user_id=4579 Taco, do you have an example of the "another problem" that you mention? I thought I had dealt with that, by not dumping obj_tab[k].int2 and resetting it to 0, and indeed it seems to work when I try it. To be precise about what I tried, I added the lines % \pdfrefximage\pdflastximage \par\vfil\penalty-10000 % before the \dump command in test-fmt2.tex. Both the generated PDFs (test-fmt2.pdf and test2.pdf) seem okay. Incidentally, it's easy to make a test, along the lines of test2, that requires head_tab[obj_type_xform]. So I guess that should be dumped too. ---------------------------------------------------------------------- Comment By: Taco Hoekwater (taco) Date: 2007-07-02 10:34 Message: Logged In: YES user_id=1608 The objects (and their numbers) are saved in the formats as well ---------------------------------------------------------------------- Comment By: Hartmut Henkel (hhenkel) Date: 2007-07-02 10:30 Message: Logged In: YES user_id=929 how can test2 work anyway? the pdfximage reserves an absolute object number (not something like an image number), and \pdflastximage gives this object number. But later in the real document objects are numbered in the natural way in ascending order, so how can an image object number fixed already in the format fit into this sequence?

Presumably the same should be done for pdf_obj_count and pdf_xform_count. Whether this is sufficient, I have no idea: none of us have tested forms or raw objects, have we? ---------------------------------------------------------------------- Comment By: Robin Houston (robinhouston) Date: 2007-06-30 12:08 Message: Logged In: YES user_id=4579 A minor bug in the initex-refximage-dump.patch: the test for fixed_pdfoutput=1 ought to be fixed_pdfoutput>0, otherwise it will fail with \pdfoutput=2, say. Another unrelated problem is that, if you load an image from the .ini file, and then load and display another image from the .tex file, the first image will appear where the second one ought to be. I'll try and find out why this is happening. (Incidentally, I haven't (yet?) discovered any problems stemming from not (un)dumping the linked list headers.) ---------------------------------------------------------------------- Comment By: Robin Houston (robinhouston) Date: 2007-06-29 20:08 Message: Logged In: YES user_id=4579 Argh! Interesting, thanks. Clearly my understanding of the pdftex code is patchy at best. That said, what is gained by dumping and restoring the head_tab?

I don't know the workings of WhizzyTeX in detail: it is conceivable that their in-document dump would be affected. However, it is unlikely that WhizzyTeX will indeed require both the output as well as the dump (the dump may well contain pictures, for example from floats that are going to be placed later), so there is at least a reasonable way to tackle this from the macro level (divert \shipout in the manner of the everyshi.sty package). At least mylatex.ltx (and consequently preview-latex) should work fine: \shipout before \begin{document} would be extremely unusual and would result in strange results, anyway. David ---------------------------------------------------------------------- Comment By: Taco Hoekwater (taco) Date: 2007-06-28 21:09 Message: Logged In: YES user_id=1608 Small limitation that I have yet to implement: the ability to move stuff over from the initex run means that if initex actually creates a pdf file, dumping a format should be disallowed, or silently ignored. Attempting to keep track of two disjunct pdf documents is just too hard for me. Note that I do not want to prohibit pdf creation from initex. Just that you can't create a pdf document _as well as_ perform a \dump. ---------------------------------------------------------------------- Comment By: Robin Houston (robinhouston) Date: 2007-06-28 17:01 Message: Logged In: YES user_id=4579 Bravo!

The image _data_ is not included (that would be really hard to do in a portable way), and therefore the undumping routines have to redo most of the work of \pdfximage, but this is transparent to the user except that the tests for \pdfminorversion and \pdfinclusionerrorlevel tests are re-done. The patch also saves some pdftex arrays that are needed to rediscover the object. This could eventually be extended to make sure \refxform et al work as well. As of now, that is untested due to lack of example. Comments and testing welcome, as always. ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2007-06-26 23:01 Message: Logged In: YES user_id=421 Sorry, pdf things work different then dvi, so we can not make \pdfximage etc. in ini mode without a lot of work; we will probably disable a bunch of primitives. ---------------------------------------------------------------------- Comment By: Robin Houston (robinhouston) Date: 2007-06-26 15:49 Message: Logged In: YES user_id=4579 Simplifying the example by eliminating the graphics package: ==> foo.ini <== \documentclass{minimal} \newbox\picbox \pdfximage{pic.pdf} \setbox\picbox\hbox{\pdfrefximage\pdflastximage} \dump ==> foo.tex <== \begin{document} \box\picbox \end{document} Also, I see now that my comparison with dvi-mode is indeed a false one, because the mechanisms are quite different, and the DVI graphics driver only has to include a \special, rather than the graphic itself. A simple solution, I suppose, would be to make \pdfrefximage (and, presumably, the other \pdfrefx commands) invalid in IniTeX mode. Perhaps this is too brutal, since it forbids certain harmless activities such as finding the dimensions of an image from an .ini file; and of course I would be delighted if it were made to work instead. ---------------------------------------------------------------------- Comment By: Reinhard Kotucha (reinhard) Date: 2007-06-26 01:26 Message: Logged In: YES user_id=4195 Martin, you probably can't do everything in a format file.

Thanks. If you replace the PDF image by an EPS file, and use -output-format dvi, then it does work. That suggests to me that the problem is not fundamentally caused by a limitation of IniTeX. But I don't know enough about the inner workings of the \includegraphics command to be sure about that. (Perhaps PDF graphics are handled in a sufficiently different way for this to be a false comparison?)
