[Fwd: [tex-live] more test images]
by Taco Hoekwater 04 Jan '07

04 Jan '07

Hi all, See below for test images of TL 2006. Does anobody have the time to test if the context on the images runs properly? I do not use TeXLive myself, nor do I have enough time to verify all is well, but imho it is important that someone tests context before the final images are created.

Updated i386-linux binaries, but still from me. (Staszek, do you think you'll be able to try that build soon?) ftp://tug.org/texlive/Images/test as usual. Thanks, k _______________________________________________ TeX Live mailing list http://tug.org/mailman/listinfo/tex-live

XeTeX fails to create formats

Hello Hans, when I tried to create XeTeX formats today (it might be that I screwed up something on my system as well) I got the following error: loading : Context Encoding Macros (pdf) ! Undefined control sequence. l.63 \ifcase\pdfgentounicode \else \expandafter \endinput \fi ? Mojca (Is there any ctxtools --degrade? ;)

Re: [dev-context] [NTG-context] debian context updates
by Sanjoy Mahajan 03 Jan '07

[CC'ing to dev-context instead of ntg-context] I noticed that the Modes manual (mmodes.pdf) wasn't included in the context*.deb's. So I diffed the list of pdf manuals in the context*.deb against the full list at <http://pragma-ade.com/dir/general/manuals/>, then looked through for the most useful to add to the context packages: mchinese.pdf mmodes.pdf enattab.pdf mchart.pdf mlabels.pdf luatex.pdf mk.pdf mmlexamp.pdf mmlprime.pdf mmodes.pdf mpattern.pdf mpdftools.pdf mpstopdf.pdf msplit.pdf mtexmfstart.pdf mwidget-s.pdf mxmltools.pdf xfigbase.pdf xfigures-s.pdf xmathml-s.pdf xcorresp.pdf xchemml-s.pdf xphysml-s.pdf xsteps-s.pdf xxmldir.pdf xmanipulate.pdf -Sanjoy `A nation of slaves is always prepared to applaud the clemency of their master who, in the abuse of absolute power, does not proceed to the last extremes of injustice and oppression.'

Inconsistent Reference Counting
by Mike Bird 01 Jan '07

01 Jan '07

References are classified as forward or backward based on comparison of \crossreferencenumber against the sequence number of the reference loaded from the previous pass. \crossreferencenumber is incremented on all reference definition writes including duplicates. References loaded from the previous pass do not include duplicates. Thus forward/backward classification (e.g. in \somewhere) is wrong in the presence of duplicate references. One fix would be to not increment \crossreferencenumber if this reference has already been written to the file. Does anyone have any suggestions how to do this? Thanks, --Mike Bird

mptopdf: produces PDF with 'unknown operator' error
by Sanjoy Mahajan 01 Jan '07

01 Jan '07

The following test file (included in the attached .zip) produces errors when test.pdf is viewed in xpdf (v3.0): Error (1004): Unknown operator 'D' Error (1006): Too few (0) args to 'J' operator =================== begin: test.tex ================== % xpdf error: % Error (1004): Unknown operator 'D' % Error (1006): Too few (0) args to 'J' operator \pdfcompresslevel=0 \defineoverlay [foregraphics] [\positionoverlay{foregraphics}] \setupbackgrounds [page] [background={foreground,foregraphics}] \starttext \hpos{r13}{4} \hpos{r23}{7} \quad \hpos{r24}{11} \startMPpositiongraphic{mypos:line} path pa, pb, pab ; numeric na, nb ; initialize_box(\MPpos{\MPvar{from}}) ; na := nxy ; pa := llxy..lrxy..urxy..ulxy..cycle ; initialize_box(\MPpos{\MPvar{to}}) ; nb := nxy ; pb := llxy..lrxy..urxy..ulxy..cycle ; if na=nb : pab := center pa -- center pb ; pab := pab cutbefore (pab intersectionpoint pa) ; pab := pab cutafter (pab intersectionpoint pb) ; pickup pencircle scaled 1pt ; draw pab withcolor .625yellow ; anchor_box(\MPanchor{\MPvar{from}}) ; fi ; \stopMPpositiongraphic \startpositionoverlay{foregraphics} \setMPpositiongraphic{r13}{mypos:line}{to=r24} \setMPpositiongraphic{r23}{mypos:line}{to=r24} \stoppositionoverlay hi \stoptext =================== end: test.tex ================== The simplest way to see the problem is to convert the intermediate EPS graphic to pdf by hand (with mptopdf), and that pdf file shows the same problem. So I run the following to get an uncompressed pdf file: texexec test.tex mptopdf test-mpgraph.1 pdftk test-mpgraph-1.pdf output test-mpgraph-1-uncompressed.pdf uncompress Then view either test-mpgraph-1.pdf or test-mpgraph-1-uncompressed.pdf (in xpdf). It's line 19 (" D J") in test-mpgraph-1-uncompressed.pdf that causes the problem. The original eps file (test-mpgraph.1) has a definition for D, which I think is "/D{[] 0 setdash}bd" (if I parsed the postscript right). But the converted PDF doesn't know the definition. Which may cause the J operator to have too few arguments. The attached zip file has all the files that result from running the above commands, including a (GNU) Makefile to reproduce the whole thing. I'm using the 2006.12.27 version of ConTeXt, with mptopdf 1.3.2, on Ubuntu Linux (tetex 3.0, xpdf 3.0). The files display correctly despite the warnings, but a more complex example (from which this came) has misplaced connecting lines. I don't know if it is caused by these operator problems. However, I figured it's worth worrying about this simpler case first, and only then seeing what problems remain in the more complex example. -Sanjoy `A nation of slaves is always prepared to applaud the clemency of their master who, in the abuse of absolute power, does not proceed to the last extremes of injustice and oppression.'
