Clip an image with a svg
by juh+ntg-context＠mailbox.org 03 Jan '25

03 Jan '25

Dear all, I found this example in the garden. \startMPclip{circleclip} clip currentpicture to fullcircle shifted (.5,.5) xscaled \width yscaled \height ; \stopMPclip \clip[nx=1,ny=1,mp=circleclip]{\externalfigure[hacker.png]} Aside from the fact that I failed to understand the shifted argument by playing around with values, I wonder if it is possible to use a SVG as clip for an image. The SVG is something like this: <?xml version="1.0" encoding="UTF-8"?>  <svg width="20.887mm" height="17.613mm" version="1.1" viewBox="0 0 20.887 17.613" xmlns="http://www.w3.org/2000/svg"> <g transform="translate(152.66 -101.94)"> <path d="m-150.94 114.93c-0.5424-1.3121-0.58209-2.9382 0.18256-5.2163 2.3566-7.0175 11.139-8.7098 15.878-3.0594 7.6978 8.7032-11.506 16.052-16.06 8.2756" fill="none" stroke="#dd4901" stroke-linecap="round" stroke-width="2"/> </g> </svg> I guess that there might be a way to translate this to Metafun or Metapost, if I can't use SVG directly. In my real life use case I want to have a bleeding image at the top or the bottom of the page which can be clipped by the form while size and position of the form relative to the image and relative to the page shall be set by parameters either in \clip or in the definition of the MPclip. TIA juh

How to control specific cells in setupTABLE?
by Joel 02 Jan '25

02 Jan '25

I used this code to create a "logic grid puzzle". See this picture (https://en.wikipedia.org/wiki/Logic_puzzle#/media/File:Logic_grid.png) for how it should appear. I'm having trouble getting the grid to show up right, I made a thicker grid (1pt) to the right of cols 1, 6, 11, and 16, but when rendering the other thinner rules, it creates strange problems, with some cell having thick rules on the bottom too. Additionally, I can't figure how to make the stair-step effect by turning off the borders of some cells. I can't find any instructions in the manual fro how to specify specific cells or a range of cells that won't be getting borders. Any suggestions how to make it look like the table in the picture? --Joel \starttext \startsetups[logicGrid] \setupTABLE[topframe=off, bottomframe=off, leftframe=off, rightframe=off] \setupTABLE[r][1][height=1in] \setupTABLE[c][1][leftframe=off,rightframe=off,width=1in,align={middle,right}] \setupTABLE[c][each][align={middle,center},height=0.25in,width=0.25in] \setupTABLE[c][2:16][align={middle,center}] \setupTABLE[r][each][align={middle,center}] \setupTABLE[c][1,6,11,16][rightframe=on, rulethickness=1pt] \setupTABLE[c][2,3,4,5,7,8,9,10,12,13,14,15][rightframe=on, rulethickness=.5pt] \setupTABLE[r][1,6,11,16][bottomframe=on, rulethickness=1pt] \setupTABLE[r][2,3,4,5,7,8,9,10,12,13,14,15][bottomframe=on, rulethickness=.5pt] \stopsetups \setvalue{topLabel1}{Red} \setvalue{topLabel2}{Yellow} \setvalue{topLabel3}{Green} \setvalue{topLabel4}{Blue} \setvalue{topLabel5}{12} \setvalue{topLabel6}{15} \setvalue{topLabel7}{18} \setvalue{topLabel8}{21} \setvalue{topLabel9}{Marmite} \setvalue{topLabel10}{Honey} \setvalue{topLabel11}{Jam} \setvalue{topLabel12}{Marmalade} \setvalue{topLabel13}{Extra1} \setvalue{topLabel14}{Extra2} \setvalue{topLabel15}{Extra3} \setvalue{sideLabel1}{Peter} \setvalue{sideLabel2}{Jane} \setvalue{sideLabel3}{Simon} \setvalue{sideLabel4}{Alice} \setvalue{sideLabel5}{Marmite} \setvalue{sideLabel6}{Honey} \setvalue{sideLabel7}{Marmalade} \setvalue{sideLabel8}{Jam} \setvalue{sideLabel9}{Label9} \setvalue{sideLabel10}{Label10} \setvalue{sideLabel11}{Label11} \setvalue{sideLabel12}{Label12} \setvalue{sideLabel13}{Label13} \setvalue{sideLabel14}{Label14} \setvalue{sideLabel15}{Label15} \bTABLE[setups=logicGrid] % Top labels \bTR \bTD \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel1}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel2}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel3}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel4}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel5}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel6}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel7}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel8}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel9}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel10}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel11}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel12}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel13}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel14}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel15}} \eTD \eTR % Side labels and grid rows \bTR \bTD[left] \getvalue{sideLabel1} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel2} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel3} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel4} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel5} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel6} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel7} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel8} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel9} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel10} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel11} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel12} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel13} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel14} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel15} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \eTABLE \stoptext

whitespace inside synonym
by damien＠thiriet.web4me.fr 02 Jan '25

02 Jan '25

Hello, I am using the synonym mechanizm to design a glossary for my pupils. I am stuck with this: how can I insert a whitespace inside a synonym definition? What I achieved yet is: \definesynonyms [vocabulaire] [vocabulaire] [\LaDef] \starttext \vocabulaire{Unionpersonnelle}{Deux États sont en union personnelle lorsqu’ils ont le même souverain} \Unionpersonnelle\ \placelistofvocabulaire \stoptext I would like to typeset Union personnelle, without inserting a UTF-8 non breakable space. I tried {{Union personnelle}}, but don't know how may I escape the space in the macro. The answer may lay in lowlevel-macro, but I couldn't find it. Happy new year everyone! Damien Thiriet

[ scaling colors ]
by vm 01 Jan '25

01 Jan '25

with the environment of \startMPcode you can scale a color with a factor like 0.25red and 0.5blue But this not seem to work when you define a color yourself first definecolor [ name = "MyColor", r = .5, g = .25, b = .25 ] ; fill fullsquare xyscaled (40mm, 15mm) withcolor "MyColor" ; fill fullsquare xyscaled (40mm, 15mm) shifted (42mm, 0mm) withcolor 0.5"MyColor" ; What would be the correct way to scale self defined colors? .F

Hi, It's about end of the year, so I updated lmtx. The most significant "change" is that columnsets are in the processed of being replaced which involves a "change in approach". As a consequence, when you use that mechanism - we're not sure how many actually do - and want the old code to kick in you need to load the "oldcolumnsets" module. Mikael S and I have been working on the new implementation but are not finished. We plan to have a reasonable stable version around may 2025 and a release at the ctx 2025 meeting when we also hope to have a new (additional) manual ready. We also test on real (complex) documents which triggers new challenges and solutions. The current code works ok but can best not be used for production (and some new features are undocumented anyway). Teaser: deep down the approach is quite different from the previous one but more reliable and it produced better quality output. Columnsets are also the mechanism that parallel document(stream)s will use. Like upgraded math and (multipass) paragraph optimization the mechanisms used are also a quite fundamental extensions that will be documented independently and likely used elsewhere.

issue when the encapsulation ‘startitem stopitem’ command is in another self-defined command

hi, I'm creating a command that can format multiple choice questions on my own. I've done most of it at the moment. But I want more, so I'm trying to create more versions of this command that is already nearing completion. So I'm using the following command to create a command with more possibilities. I've noticed that ‘startitem stopitem’ isn't working. Their location and serial number are anomalous. %%%% Removed some unnecessary commands to show what the problem was. % macros=mkvi \starttext \unprotect \installnamespace {chitem} \installcommandhandler \????chitem {chitem} \????chitem \appendtoks \setuevalue{\e!start\currentchitem}{\startnamedchitem [\currentchitem]}% \setuevalue{\e!stop \currentchitem}{\stopnamedchitem}% \to \everydefinechitem \tolerant\protected\def\markedchoice#1{{\sym{@} \red sym : #1}} \tolerant\protected\def\normalchoice#1{\startitem normal : #1\stopitem} \tolerant\protected\def\\calc_maxwidth#1{} %The longest option text is calculated by comparison to % determine the number of columns that can be typeset \tolerant\protected\def\startnamedchitem[#chitem]#*[#mark]#*[#option]#*#choice\stopnamedchitem% {\begingroup % \ifarguments 0\or :1\or +2\or =3\or !4\fi \def\currentchitem{#chitem}% \edef\p_correctmark{*}\edef\p_paramark{#mark}% \calc_maxwidth{#choice}% \ifx\p_paramark\p_correctmark \markedchoice{#choice}% \else \normalchoice{#choice}% \fi\endgroup} \def\stopnamedchitem{} \definechitem[chitem] \protect \startitemize[n,horizontal,two]% % The process of calculating the number of formattable columns % has been removed and the results of the calculations are used directly. \startchitem xxx\stopchitem \startchitem[*]correct choice\stopchitem \startchitem xxx\stopchitem \startchitem xxx\stopchitem \stopitemize \stoptext %%%%% thanks for any help, autumnus
