space between label and number
by dalyoung 29 Jun '11

29 Jun '11

Hi, By Hans's help, the labels of figures and of tables are appeared in Korean after setting \mainlagnuage[kr]. (\placefigure of \placetable ) Thanks! However, there is no space between label and number like "그림1" or "표3". I tried to add a space like "그림 " in the file char-def and some other files, but it won't work. When mainlanguage is english, the labels are "Figure 1" or "Table 3". There exists a space. How to add a space in this case? I have another question. Is it possible to calculate the remaining length to the bottom of the page? I'd like to add a big frame to fit the remaining space after some texts. I think that it is possible in ConTeXt. Thank you for reading. Best regards, Dalyoung

Scaling down the resolution of used pictures
by Cecil Westerhof 29 Jun '11

29 Jun '11

At the moment it is not very important, but my other question remembered me about an old situation. I do not use graphics a lot in my ConTeXt files. But some time ago I used several pictures with a very high resolution. This made the resulting PDF very big. I did not expect the PDF printed on a printer with a higher resolution as 1200 DPI. Is there a way to have the included graphics not be bigger as necessary (without changing the original pictures)? Again, at the moment it is not urgent. But when I come in the same situation again, it would be nice if the resulting PDF was not five times as big as necessary. And maybe the answer is useful for someone else also. ;-} -- Cecil Westerhof

Working with graphics
by Cecil Westerhof 29 Jun '11

29 Jun '11

I am using graphics in my PDF document. First I used something like this: \midaligned{\externalfigure[graphics/priceList][width=1\textwidth]} Initially this worked good enough. But now I have both little pictures and pictures that are large in the y-direction. At this moment I change the width parameter manually. But I would like something like the following: - A picture is not stretched more as a certain value. (Say two.) - A picture is never to wide. - A picture is never to high to fill more as 75% of a page. Is this something that is possible? Also: is it a good idea to use \useexternalfigure, or is this only necessary when a picture is used more as once. -- Cecil Westerhof

CMYK colors not as expected
by Hans van der Meer 29 Jun '11

29 Jun '11

I would be pleased to get some advice from "color-knowledgeable people" on the following matter. In TV-broadcasts there are usually two kinds of subtitles present: Teletext as characters and DVB as pixels. These can be extracted and rendered with Metapost. I have done this, but I am not very satisfied with the colors produced. On the television screen they look bright, when rendered in Metapost they are dull and muddy. The text is barely readable. As I am fairly sure I did extract the correct bits from the CLUT contained in the stream, I wonder if I am doing something not right at the Metapost side. In the datastream the values given are the most significant 6, 4, 4 and 2 bits of respectively Y, Cr, Cb, T. These are scaled to the values given to Metapost by dividing them by 255. In the zip one finds the program (ConTeXt MKIV) used for typesetting, an example pixel map with clut, and the output. I would be obliged to get some comments. Hans van der Meer

math: command for absolute value: `\define\abs[1]{\lvert #1 \rvert}` throws `\lvert ->\Udelimiter`.
by Paul Menzel 29 Jun '11

29 Jun '11

Dear ConTeXt folks, I want to define `\abs` as the command for the absolute value. The following minimal example is also attached. \define\abs[1]{\lvert #1 \rvert} \starttext $\lvert 2 \rvert$ $\abs{2}$ \stoptext This does not work though. $ context abs […] This is LuaTeX, Version beta-0.70.1-2011051923 (rev 4277) \write18 enabled. (abs.tex ConTeXt ver: 2011.05.18 22:26 MKIV fmt: 2011.5.27 int: english/english […] ! Missing $ inserted. system > tex > error on line 1 in file abs.tex: Missing $ inserted ... 1 >> \define\abs[1]{\lvert #1 \rvert} 2 \starttext 3 $\lvert 2 \rvert$ 4 5 $\abs{2}$ 6 \stoptext 7 <inserted text> $ <to be read again> \Udelimiter \lvert ->\Udelimiter "4 "0 "7C l.1 \define\abs[1]{\lvert #1 \rvert} ? How should I do that correctly? I took that example from the user’s guide of the amsmath package (`texdoc amsldoc`). Thanks, Paul

Large Figure on Landscape Orientation
by Kip Warner 28 Jun '11

28 Jun '11

Hey folks, I'm having difficulty getting an external image to display on its own page, with the page in landscape mode, and the image uniformly scaled as large as can fit on that page. Relevant portions of my environment file include... \setuplayout [\c!location=\v!middle, \c!style=\ss, \c!backspace=2.5cm, \c!topspace=1.5cm, \c!width=16cm, \c!margindistance=.25cm, \c!margin=2.5cm, \c!height=\v!middle] \definelayout [fullpage] [\c!backspace=0pt, \c!topspace=0pt, \c!width=\v!middle, \c!height=\v!middle, \c!header=0pt, \c!footer=0pt] \definepapersize[main][A4][A4] \definepapersize[diagram][A4,landscape][A4,landscape] And the actual image in my component is here: \page \setuppapersize[diagram] \placefigure [force][figure:MyImage] {My image caption.} {\externalfigure[MyImage][factor=max]} \page \setuppapersize[main] The document is all in portrait mode, save the page with the figure which is landscaped, as intended. But the image sits only occupying the top left quarter of the page. I've tried changing factor from max to broad and fit, and to no avail. -- Kip Warner -- Software Engineer OpenPGP encrypted/signed mail preferred http://www.thevertigo.com

\about[node] quotation marks
by Kip Warner 28 Jun '11

28 Jun '11

Hey list, Is there any way to have ConTeXt not surround the link in the text with quotation marks when using \about[some_node]? -- Kip Warner -- Software Engineer OpenPGP encrypted/signed mail preferred http://www.thevertigo.com

Text Background
by H. Hodges 27 Jun '11

27 Jun '11

I can't seem to set a background on one of my paragraphs. I'm using: \definetextbackground[intro][backgroundcolor=gray, location=text,color=blue] along with \starttextbackground[intro] paragraph \stopbackgroundtext in the body of the document. I got the impression from one of the manuals that \setuptextbackground was only necessary in the case of multiple \definetextbackground statements, but I tried including it anyhow. Still, I'm getting no background whatsoever.

Sanskrit Devanagari characters
by Kip Warner 27 Jun '11

27 Jun '11

Hey list, I need to sprinkle my book with a few Sanskrit words written in the Devanagari script. I don't need to write complete paragraphs in it, but just a word or two inline. Can anyone show me the ConTeXt source to do such a thing, with, say "तरीकिन"? -- Kip Warner -- Software Engineer OpenPGP encrypted/signed mail preferred http://www.thevertigo.com

TOC look broken by \definehead
by Procházka Lukáš Ing. - Pontex s. r. o. 27 Jun '11

27 Jun '11

Hello all, the TOC look depends on whether or not another head was defined: ---- \definehead[CHAPTER][chapter] \definehead[SECTION][section] % TRY TO COMMENT THIS LINE! \definecombinedlist[content][chapter,CHAPTER] \starttext \placecontent \page \chapter{Cha1} \CHAPTER{Cha2} \chapter{Cha3} \chapter{Cha4} \CHAPTER{Cha5} \stoptext ---- Both PDFs - generated with/without "\definehead[SECTION][section]" - are attached. If the definition of \SECTION is present, TOC members generated by \CHAPTER are shifted. Why? - This seems to me a bit weird. Is there a way how to keep the TOC (non-shifted) look?
