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 16:34 Message: Logged In: YES user_id=421 The patch was missing. Fixed. ---------------------------------------------------------------------- Comment By: Martin Schröder (oneiros) Date: 2006-09-17 14:30 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

Therefore the problem is only visible with very long document like Reinhard's test file. Taco's suggestion for the problem: > I strongly suggest you just change the penalty size to 4, because > the other possibilities that I see have much more impact. Starting > from the head node each time is quite slow (much slower than the > speed penalty incurred by the extra size of the penalty node). > > There are other options, but increasing the penalty size is simplest > by far.

There is still one catch that | pdftex without synctex still has glue_node_size=2 and | doesn't need this change.

Sorry. ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2008-05-27 16:48 Message: ok then this should be fixed as the spec says. BTW, it doesn't really solve the reported problem (ü will come after eg z). ---------------------------------------------------------------------- Comment By: Hans Hagen (hagen) Date: 2008-05-27 16:03 Message: the spec says: The Names entries in the leaf (or root) nodes contain the tree’s keys and their associated values, arranged in key-value pairs and sorted lexically in ascending order by key. Shorter keys appear before longer ones beginning with the same byte sequence. The encoding of the keys is immaterial as long as it is self-consistent; keys are compared for equality on a simple byte-by-byte basis. so, it's just bytes ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2008-05-27 15:43 Message: this is a problem, but it's not clear to me how it should be fixed. Assume that we translate "\374" to the corresponding charcode (0374 = 252) before sorting, then how we decide the lexicographic order of that char? it can be intepreted as ü but also can be eg ytilde or something different, depending on the encoding we use.

pdf font inclusion error (with partial patch)
by Taco Hoekwater 26 Nov '09

26 Nov '09

Hi, I have added the patch below to luatex and a similar one-liner for my local pdftex because we here ran into a pdf document that has the following oddness: 5 0 obj << /F15 << /Type /Font /Subtype /TrueType /BaseFont /WIDGBH+ArialMT /Encoding /WinAnsiEncoding /FirstChar 0 /LastChar 255 /FontDescriptor 8 0 R /Widths 7 0 R >> ... >> 6 0 obj << /Type /Page /Parent 4 0 R /MediaBox [ 0 0 595.276 841.89 ] /Resources << /Font 5 0 R /ProcSet [ /PDF /Text /ImageB /ImageC ] >> /Contents 13 0 R >> endobj Current pdftoepdf.cc expects to find indirect references inside object 5, without the patch it generates a fatal error. The patch itself is only a quick fix that works thanks to my setting of \pdfinclusioncopyfonts, as I do not know how to fix the 'other' case, sorry.

[pdftex-Bugs][4294] issue with isolated/non-isolated page transparency group
by pdftex-bugs＠sarovar.org 17 Nov '09

17 Nov '09

Bugs item #4294, was opened at 2009-09-02 00:43 >Status: Closed Priority: 3 Submitted By: John Owens (jowens) >Assigned to: Martin Schröder (oneiros) Summary: issue with isolated/non-isolated page transparency group Category: PDF inclusion Group: None >Resolution: Works For Me Initial Comment: (The last bug didn't show up. So I am posting a web link to the three files referenced below: http://tinyurl.com/n4jjm4 ) Howdy, I'm attaching 3 files. One is a tar.gz of a LaTeX document. When we first submitted the paper built from the document, we used dvips and Distiller. Now we're using pdflatex for the final version. Both pdfs are attached. However, strangely, page 4 on the pdflatex pdf, when viewed in Apple Preview on Snow Leopard (10.6), has substantially lighter fonts than the other pages. This is probably Preview's problem, not pdflatex's problem, and I've filed an Apple bug. However, from talking to a PDF expert (summary below), it appears that pdflatex is doing something weird, so I thought I'd bring it to your attention. The base page transparency group for page 4 is nonisolated, where for all the other pages the /I key is not present (and thus they are implicitly isolated). The PDF is correct, although a little weird--there is no point in even specifying the isolation key of a page's transparency group unless it a) contains non-normal blend modes _and_ b) will be rendered in non-device-like contexts (e.g., as an object in a larger piece of artwork). So I would argue that pdflatex should probably not even bother specifying the /I key, especially given that it appears to trigger a bug--or at least a dramatically different code path--in Preview. This _should_ have no effect, as the value of the /I key for the page group is supposed to be ignored (and treated as if it were true). Furthermore even if Preview were ignoring that requirement, the page doesn't have any blend modes, so mathematically it shouldn't be producing a different result. But my guess is this: Preview is rendering page 4 into a nonisolated transparency group using an initial, opaque, all-white backdrop, when it should be completely ignoring the /I key and rendering into a completely transparent backdrop. This shouldn't lead to different results unless a blend mode is present. But,the isolated and nonisolated code paths are somehow sufficiently different that they generate different pixel values--due to precision or perhaps an actual bug. But most of what I say is conjecture. See chapter 7.3.6 ("Page Group") of the PDF Reference Manual, sixth edition. The Distiller version doesn't even have transparency group objects on the pages (which is normal). So I wouldn't expect it to have the same issues in Preview, and it doesn't. (This is LaTeX source for a paper, so though I know you'll need the source to do your investigations and bug fixes, kindly don't do anything else with it beyond that.) $ pdflatex --version pdfTeX 3.1415926-1.40.10-2.2 (TeX Live 2009) kpathsea version 5.0.0 Copyright 2009 Peter Breitenlohner (eTeX)/Han The Thanh (pdfTeX).
