Font installation help needed!
by Geert Verhaag 02 Oct '18

02 Oct '18

Hi, I'm currently using ConTeXt version: mtx-context | ConTeXt Process Management 0.60 mtx-context | mtx-context | main context file: /home/verhaag/context/tex/texmf-context/tex/context/base/context.mkiv mtx-context | current version: 2013.08.11 20:23 I'd like to use the Advent Pro font, so I downloaded the font and have 7 ttf files available. After looking around for some manual I found: "Integrating TrueType Fonts into ConTEXt" by Thomas A. Schmitz. Immediately I run into problems when trying to run the texfont command. My Linux (ubuntu 14.04) says: The program 'texfont' is currently not installed. I did a standalone installation years ago of this version of ConTeXt, and don't dare to upgrade because I might run into other issues, sorry! Any hints on how to procede installing the Advent Pro font to this version of ConTeXt are very much welcomed! Regards, Gerard --

When it is possible to handle an external svg file as a singe character with text, i assume there is someone on the list who could point me to the instructions as how to do that. Thanks Floris

accessing glyphs in the private area
by Ulrike Fischer 02 Oct '18

02 Oct '18

The font Coelacanth (on CTAN) has glyphs in the private area. Between 2/2017 (luaotfload in texlive 2017) and now the storing and accessing of this glyphs has changed. In the lua of the font of 2017 I find e.g. [62860]={ ["boundingbox"]=165, ["index"]=2622, ["unicode"]=62860, ["width"]=523, and the glyph can be accessed with \Uchar62860 In the current lua I now find [983910]={ ["boundingbox"]=195, ["index"]=2622, ["unicode"]=62860, ["width"]=523, }, and \Uchar62860 not longer works, one has to use \Uchar983910. Is this change intentional? How is one supposed to access such chars? The manual says about \Uchar that it "expands to the associated Unicode character." but this seems no longer to be true. A context example to test is \starttext \font\test={name:Coelacanth:mode=node;script=latn;language=DFLT;+tlig;} \test 1.: \Uchar62860 2.: \Uchar983910 \stoptext The question was triggered by this tex.sx question https://tex.stackexchange.com/questions/453224/using-glyphs-in-the-corporat… https://github.com/u-fischer/luaotfload/issues/7 -- Ulrike Fischer https://www.troubleshooting-tex.de/

Metafun scaling problem
by Lutz Haseloff 02 Oct '18

02 Oct '18

Hi Hans, hi all, I think, that recent context has a problem with scaling included pdf files. My minimal file: \startMPpage draw externalfigure "cow.pdf" ; \stopMPpage The resulting pdf is, as the original, 97x70.6 mm, all ok. If I try to scale to the original size, i get arithmetic overflow error. \startMPpage draw externalfigure "cow.pdf" xscaled 97mm yscaled 70.6mm ; \stopMPpage Whe i scale it down, the pdf gets really big. \startMPpage draw externalfigure "cow.pdf" xscaled 27.5mm yscaled 20mm ; \stopMPpage results in a pdf with width of 4.938,8 mm and height of 2.612,3 mm. I tested with recent context and luatex under windows 64 and linux-armhf. Greetings Lutz

Given how many reports are appearing in the few days that this has been exposed to a larger number of uses via LaTeX, use of PUA characters really isn't a rare occurrence at all. If you need to allocate a block for internal use wouldn't it be possible to use one of the high areas Supplementary Private Use Area-A or B (U+F0000 - U+FFFFF) (U+100000 - U+10FFFF) ? The BMP PUA block (U+E000 U+F8FF) just has so many documented uses in existing fonts.

table making ugly column sizes, how to fix?
by David Walther 02 Oct '18

02 Oct '18

Full example at the bottom. I'm making a table. So far so good. Every so often I want to make something like a section header. Regular table rows are like this: \bTR\bTC \eTC\bTC NightShift \eTC\bTC Tension Lines 146 - 150 \eTC\eTR For the section headers, I do this, and they look the way I want: \bTR\bTC 30. \eTC \bTC[nc=2,align=center,style=] \bf{Foo Bar} \eTC\eTR But then the regular lines have ugly line breaks and suddenly the column size of column 3 is squeezed. This shouldn't be, we have the whole page to work with. So, when I do my section headers this way, the columns come out sized nicely, but the section header isn't styled the way I want it: \bTR\bTC 30. \eTC \bTC\eTC \bTC[align=center] \bf{Foo Bar} \eTC\eTR Below is my minimal example you can cut and paste. How do I do the section headers without messing up the column sizing? \setuppagenumbering[alternative=doublesided,location=none,page=no] \setupfootertexts[\sans{Source: http://mywebsite}] \setupheadertexts[test column text wrapping] \setupheadertexts [] [Page \userpagenumber\ of \lastuserpagenumber] [Page \userpagenumber\ of \lastuserpagenumber] [] \setuppapersize[letter, portrait] \setuplayout[topspace=0.5in, backspace=1in, height=10in, width=7in, header=0.5in, footer=0.5in, headerdistance=0in, footerdistance=0in] \switchtobodyfont[12pt] \starttext \setupTABLE[split=repeat] \setupTABLE[r][each][toffset=3pt, boffset=3pt, loffset=3pt, roffset=3pt] \setupTABLE[c][each][leftframe=off,rightframe=off,align=right] \setupTABLE[c][first][frame=off,align=left] \setupTABLE[c][2][style=\tfx\it,align=left] \bTABLE \bTABLEhead \bTR\bTH Col1 \eTH\bTH Col2 \eTH\bTH Col3 \eTH\eTR \eTABLEhead \bTABLEnext \bTR\bTH Col1 \eTH\bTH Col2 \eTH\bTH Col3 \eTH\eTR \eTABLEnext \bTABLEbody \bTR\bTC \eTC\bTC NightShift \eTC\bTC Tension Lines 146 - 150 \eTC\eTR % This displays the way I want, but breaks the regular rows. \bTR\bTC 30. \eTC \bTC[nc=2,align=center,style=] \bf{Foo Bar} \eTC\eTR % This works with the regular rows, but doesn't look how I want. %\bTR\bTC 30. \eTC \bTC\eTC \bTC[align=center] \bf{Foo Bar} \eTC\eTR \eTABLEbody \eTABLE \stoptext

Re: [NTG-context] xtables with lua

Dear Otared, What do you mean “does not typeset correctly as expected”? I copied and tested the last example and got the result without error. One problem is that the vertical alignment is not centered as the example of Aditya’s. Would you please tell me what I miss? Thank you. Best regards, Dalyoung > > I wanted to make an observation about the last example in that page, which does not typeset correctly as expected, and also it does not work well if one wanted to make a multiplication table instead of the addition table of your examples. I think the following modification might be necessary (here for the multiplication table): >

Which color model shall I use
by Jan U. Hasecke 01 Oct '18

01 Oct '18

Hi, I would like to know, how to define colors to have a good printing quality. I am currently producing print materials for a company where all colors were defined for online usage first, so we started with defining RGB colors and then derived CMYK colors. What is the best approach for defining colors in print materials? What color model shall I use? RGB or CMYK? For the background. We have some SVG graphics we use on the website. They are defined in RGB color model. And we use them in the print materials as well. I tend to define RGB colors in my print documents so that the colors of the included SVG files match the defined colors I use elsewhere in the document. Eg. the Corporate-Blue of the Logo (SVG) will match the Blue of the headlines. I could as well define CMYK colors in the document but then I have two different color models in one document and I fear that the colors are printed in different hues. What would you do? TIA juh

Questions and observations on the div html export
by Rik 30 Sep '18

30 Sep '18

List, I have been wrestling with the div.html output produced by the export back end, and have a few questions. On the list, Hans has suggested defining elements with two commands, as: \setelementbackendtag [BlockItem] \setelementnature [BlockItem][display] \setelementbackendtag [InlineItem] \setelementnature [InlineItem][inline] These commands do not appear on the wiki or in i-context.pdf. In i-context.pdf, we find: 1 2 3 \setelementexporttag [...][...][...] OPT 1 NAME 2_export_ nature pdf 3 inline display mixed I have tried this latter command in many variations, and cannot understand just how to use it. For example, both of these: \setelementexporttag[BlockItem][display] \setelementexporttag[BlockItem][export][display] generate divs with class="display", when one wants class="BlockItem". But the pair \setelementbackendtag and \setelementnature works for that. Is there any documentation for any of these commands, beyond the syntax in i-convert for \setelementexporttag? The \startelement command takes one or two arguments. The first is the element name, and is required. What is the intended use of the second argument, a list of key/value pairs? Nothing seems to be passed via the back end to the div.html (or raw.xml) file. Next, the back end generates div elements for both block and inline scopes, while html calls for span elements as inline containers. Defined highlights, which are by nature inline containers, are also translated to divs instead of spans. The generated css does identify the divs with display: block and display: inline as appropriate, but that does not help with tools that work with html. (HTML Tidy, for example, will happily introduce extra whitespace because it inserts a newline before a div that should really be a span.) Finally, what is meant by mixed (with respect to inline and display)? If anyone else has figured out some of this stuff, please send some pointers. -- Rik
