Minimal size of page
by Jean Magnan de Bornier 16 Feb '08

16 Feb '08

Hi all, I want to make a dvi output of one or more math formulas, on a page of minimal size, ie the size of the formula; I had asked the same thing for a metapost/fun graphic sometime ago, the answer had been: \startMPpage ... \stopMPpage but I guess I can't use that here! tia, -- Jean

interaction query
by Alan Bowen 16 Feb '08

16 Feb '08

In my preface, I have \setupinteraction[state=start,color=blue,style=rm] \definehead[LevelBHead][subject] \setupsectionblock[LevelBHead][number=no,page=right] \setuphead[LevelBHead][style={\tf\rm},interaction=yes] and in the source file proper, \LevelBHead{Comment 3: {\em In de caelo} {\tf 481.12--15}\hfill ref.\ \at[fnComment3]n\in[fnComment3]} When I compile the file I get the proper heading and the cross- reference works as it should. What is odd is that this reference is not in blue. All my other kinds of cross-references look and behave as they should. Any remedies for this admittedly minor problem will be greatly appreciated. Cheers, Alan PS I am using mkii. A.

Problem with Portuguese hyphenation
by Maurício 16 Feb '08

16 Feb '08

Hi, In Portuguese, the rule about hyphenating word that contain hyphens themselves is to preserve the hyphen in the next line. For instance, the sentence "Seria bom se eu pudesse tê-lo mantido como amigo, mas por mais bem-intencionado que eu fosse, não foi possivel" should be hyphenated like that (justification adapted just for that example): Seria bom se eu pudesse tê- -lo mantido como amigo, mas por mais bem- -intencionado que eu fosse, não foi possivel. However, Context does that like this way: Seria bom se eu pudesse tê- lo mantido como amigo, mas por mais bem- intencionado que eu fosse, não foi possivel" What should I do to correct that? Thanks, Maurício

XML: mapping definiton on the fly?
by Johannes Graumann 15 Feb '08

15 Feb '08

Dear XML-processing inclined, I was wondering whether with MarkV it is possible to parse an XML file that contains style definitions as well as there usage and create context mappings for them on the fly. In the example fragment below this would mean: - scan the file until hitting the "<office:automatic-styles>" tag - analyze the style definition, find it to be of family text of name T1 requiring bold fonts - construct a context/XML mapping along the lines of \startxmlsetups T1 \bf{\xmlflush{#1}} \stopxmlsetups - keep on scanning, when hitting the style invocation: use the dynamically generated mapping. Please excuse the hobbyists nomenclature. Thank you for your time and insight, Joh <?xml version="1.0" encoding="UTF-8"?> ... <office:automatic-styles> <style:style style:name="T1" style:family="text" > <style:text-properties fo:font-weight="bold" style:font-weight-asian="bold" style:font-weight-complex="bold" /> </style:style> </office:automatic-styles> <office:body> <office:text> ... <text:p text:style-name="Standard" > Dies <text:span text:style-name="T1">ist</text:span> ein Text. </text:p> </office:text> </office:body> ...

latest release(s) and XeTeX

Is anybody using XeTeX with the latest releases? Even the most basical "Hello World" document doesn't compile with this error (both stable and beta, regardless if the document actually uses Latin Modern or not). Any hints?

However, xpdf/kpdf/etc. do not handle 16-bit color, unlike acroread and ghostview. Note also that pdflatex automatically downgrades 16-bit color images to 8-bit. Alan

However, no, neither of the proposed solutions work. 1. Of course, I tried "\pdfimagehicolor=1" without results before posting the question. (I would NEVER think about asking for help without trying different possibilities myself...) 2. "\setupcolors[state=start]" was also in my original file, but did not seem to make a difference, so I posted a most simplified example. What to do? I would think that there is something wrong with my configuration (debian/unstable), however pdflatex works just fine. Alan (P.S. Why would one need to specify \pdfimagehicolor in any case; From a user's point of view, shouldn't it just work transparently?)

Subpagenumbers and unwanted last page with MkIV

Hi, the following example with subpagenumbers works fine with MkII, but MkIV produce a extra last page and I try to get rid of this page. \setupsubpagenumber [number=1, way=bytext, state=start] \setupheadertexts[\subpagenumber--\numberofsubpages] \starttext \dorecurse{8}{\input knuth\par} \page \resetsubpagenumber \dorecurse{8}{\input zapf\par} \stoptext Greetings, Wolfgang

16-bit png
by Alan BRASLAU 15 Feb '08

15 Feb '08

Hello, I am having problems including 16-bit png files in ConTeXt. In the following example, red.png is a 800x600 image of red pixels. The resulting test.pdf shows a BLACK rectangle. (The same problem exists with real images.) However, I can produce the desired result with my installation under pdflatex... $ cat test.tex \starttext \externalfigure[red][width=\textwidth] \stoptext $ file red.png red.png: PNG image data, 800 x 600, 16-bit/color RGB, non-interlaced $ texexec test $ cat test2.tex \documentclass{article} \usepackage{graphicx} \begin{document} \includegraphics[width=\textwidth]{red} \end{document} $ pdflatex test2 My distribution (debian + texlive) uses This is pdfTeXk, Version 3.141592-1.40.3 (Web2C 7.5.6) in both cases. Does this have something to do with \pdfimagehicolor? Thank you
