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

PGF and definecolor
by Flavien Lambert 14 Feb '08

14 Feb '08

Dear all, I am a newbie in ConTeXt. I am accustomed to use pgf in LaTeX and have seen that pgf is also a module for ConTeXt. When using some of my pgf macros in ConTeXt, I had several erros coming from the fact that colors are defined by the "same" command in both pgf and ConTeXt, namely \definecolor[mycolor][r=,g=,b=] in ConText and \definecolor{mycolor}{rgb}{,,} in pgf. It seems to me impossible to use the pgf command directly and, in the same time, impossible to use ConTeXt-defined color in pgf macros. Here is an example : \usemodule[pgf] \definecolor[mycolor][r=0.5,g=0.5,b=0.5] \starttext \pgfdeclarehorizontalshading{myshading}{1cm}{% color(0cm)=(mycolor);color(1cm)=(green)} \pgfuseshading{myshading} \stoptext There is an error with \definecolor and the shading. If you replace (mycolor) by (red) in the shading and suppress the \definecolor, it is fine. Best regards.

exploring register options
by Henning Hraban Ramm 14 Feb '08

14 Feb '08

Can someone tell me, if the following options of \setupregister are supposed to have some effect (I couldn't see any): style (pagestyle and textstyle work) command (pagecommand and textcommand work) location (Just fixed the texshow description.) I didn't check those (also undocumented): expansion maxwidth unknownreference I wonder who needs alternative b or B: the indicator (index letter) just in front of the first word without any distance is just ugly IMO and decreases readability. Other styles (alternatives) would probably make more sense, like right-aligned (flushleft) page numbers - how can I do that? Greetlings from Lake Constance!

latest beta hates most of my fonts
by Thomas A. Schmitz 13 Feb '08

13 Feb '08

the latest beta refuses to work with most of my (Greek) fonts. I have compiled the very latest trunk (rev. 1006, I think). Difficult to make a minimal example because it doesn't happen with simple "Latin" text, only when there's Greek in the file. The error message is always similar: )</Users/tas/texmf/fonts/opentype/greek/bosporos/BosporosU.otf !luaTeX error (file /Users/tas/texmf/fonts/opentype/greek/bosporos/ BosporosU.otf): Unexpected error: 85 != 92 ==> Fatal error occurred, no output PDF file produced! Does that ring a bell, or should I see if I can find a font which doesn't work in "normal" mode? The fonts are set up like this: \installfontfeature[otf][grbl] \definefontfeature [agreek] [mode=node,language=dflt,script=latn,kern=yes,tlig=yes,trep=yes, grbl=yes,featurefile=greek-babel.fea] \definefontsynonym [Serif] [name:BosporosU] [features=agreek] etc. Thomas

{{ double braces }}
by Steffen Wolfrum 13 Feb '08

13 Feb '08

Hi, I would like to use in my documents double braces for the footnote – for easily matching entire footnotes with RegEx (thus it can't confuse with the nested braces) ... text\footnote{{this is {\it one} tiny note\index{note}!}} ... and match the entire footnote with search regex for \\footnote\{\ {.+\}\} Is this save? Or are there unwanted side-effects when using \footnote {{ ... }} ? Steffen
