Why do size changes affect my math font?
by Brooks Moses 15 Aug '05

15 Aug '05

Consider the following simple document, with is a minimalist version of the slides that I'm currently working on: \starttext The variables are $u$ and $p$. \stoptext This works fine; the text is in roman and the math in italics, just as I desire. However, I need a larger font for my slides, and thus I'm also using a font size command, like so: \starttext \tfc The variables are $u$ and $p$. \stoptext This causes the math to be in roman instead of italic. (It's not in "text font" per se; an \it after the \tfc will italicise the text but not the math, creating a quite odd effect.) Is there a reason for this? What's the cleanest way to fix it for all the various size commands? Thanks, - Brooks

A question on drawing functions in MetaFun
by Jin-Hwan Cho 15 Aug '05

15 Aug '05

I tried to generate "Figure 9.2 An example of a graphic with labels along the axes." in metafun-p.pdf (p.209), but could get only graphics without labels. I used the codes in the page 208 as follows (see the attached file) \startMPpage StartPage ; ... codes in p.208 here ... StopPage ; \stopMPpage In this case, the generated MPS file (ch93-1-mpgraph.1) had the bounding box (0, 0, 420, 596). When I used \startuseMPgraphic instead of \startMPpage, the generated MPS file had the different bounding box (-47, -17, 300, 575), and I could see the right one. Please tell me what I missed.

Problem installing ConTeXt jedit syntax mode
by Elliot Clifton 15 Aug '05

15 Aug '05

Hi, I've added the context jedit mode files to the modes directory inside my jedit settings directory, and appended the mode to the catalogue. I get XML validation errors that state the various DELEGATEs are invalid. The external files (*-en, *-de, etc...) do not import. Why? What am I doing wrong? Elliot

math functions
by billet＠eurecom.fr 13 Aug '05

13 Aug '05

Hi, I would like to set the font used for math functions like \sin to be the body font. Of course, it should go for scriptsize when used in exponents. I tried without success to define \def\mfunction#1{{\tf\rm #1}} What is the conTeXt way to do this? Thanks for your help, Olivier

A wee bit more about OpenType (Myriad Pro)
by David Wooten 12 Aug '05

12 Aug '05

Greetings all & Adam, Having successfully installed Jenson & Minion Pro I've been trying to get Myriad Pro to install as a companion Sans (motivated in part by the fact that Adam has a nice typescript file for Warnock Pro with Myriad). I'm having some difficulties, which seem similar to difficulties I had earlier on…but apparently we finished our conversation off the list, so I can't locate what the solution was ;) (I believe it was "try updating to the latest version of LCDF from *EXPERIMENTAL*"). Before I display some error messages, I want to ask, Adam, why the Myriad Pro fontsynonyms in your typescript do not have any of the OpenType features—liga? kern? Is this due to Myriad Pro's particulars? [I've just checked, and it isn't only Myriad Pro that won't install.] I'm using Gerben's i-Installer, 2004 stable, ConTeXt updater, LCDF 2.26 (no longer in the "experimental" directory). I've also tried with the 2005 development set. The result is the same. In any case, here we go: sudo texfont --fo=/ME/texmf --ve=adobe --co=myriadpro --lcdf --pre -- ma --in TeXFont 2.2.1 - ConTeXt / PRAGMA ADE 2000-2004 mktexlsr: Updating /Users/wooten/Library/texmf/ls-R... mktexlsr: Done. encoding vector : texnansi vendor name : adobe source path : . font collection : myriadpro texmf font root : /users/wooten/library/texmf pdftex map file : texnansi-adobe-myriadpro.map source path : . processing files : all on afm path locating afm files : using pattern ./*.afm locating afm files : using otf files converting : ./MyriadPro-Black.otf to ./MyriadPro-Black.pfb [etc.] font identifier : MyriadPro-Black -> text -> tfm processing files : otf -> tfm + enc otftotfm: /usr/local/Build/TeXLive.tl2003.development/share/lcdf- typetools/glyphlist.txt: warning: No such file or directory I had to round some heights by 14.5000000 units.

\starttabulate vertical spacing
by Christoph Czarnetzki 11 Aug '05

11 Aug '05

Hello! i want to put some space between lines in a tabulate environment. \starttext \starttabulate[|l|p(1cm)|] \NC Some Text \NC Other Text \NC\NR\HL \NC Some Text \NC Other Text \crlf\NC\NR \NC Some Text \NC Other Text \NC \stoptabulate \stoptext i did it with \crlf, but this is too much for me. \godown doesnt work either. Half of a line in space would be great. I tried that with starttable too, but the \HL command in tabulate works better. The text is aligned directly under the ends of the line. So i use tabulate. And the other problem is, crlf only works if tab is set to |p|. thanks! Christoph

MPcolor problem (CMYK)
by Jin-Hwan Cho 11 Aug '05

In the MetaFun manual (metafun-p.pdf) p.117, you may see an example using the color ".5\MPcolor{cmyyellow}". But I could not generate the color. Could anyone check the attached sample?

\Shaped macro in MetaFun manual
by Jin-Hwan Cho 11 Aug '05

11 Aug '05

The third line in the page 145 in the MetaFun manual (metafun-p.pdf) says The \Shaped macro was defined as: .... some \inframed[background=Shape]{text} with a frame ... .... some \Shaped{text} with a frame ... It seems to be a typo. Let me know the exact definition of \Shaped macro. Thanks in advance.

Clipping a path to a boundary --- Being more specific
by David Arnold 10 Aug '05

10 Aug '05

Hans et al, Let me try to be more specific. Here is a file which is very typical of the way I draw graphs for my mathematics classes. When you compile, you will see the graph of the absolute value of x-1. That is, it draws the graph of y=|x-1|, but only after clipping it to the cpath. What I would like to do is draw the graph with the drawdblarrow command so that the graph of the absolute value ends in arrowheads. So, I want to clip the graph to the bounding box, save the picture, null the picture, then somehow extract the path into the variable F in its clipped form (not the original path F that extends outside the clip path) so that I can replace the command draw pic with drawdblarrow F. beginfig(0); numeric a, c; a=1; % define function f(x)=|x-a| vardef f(expr x)= abs(x-a) enddef; % draw line with given point and slope path F; F:=(-5,f(-5)); for x=-5 step 1 until 5: F:=F--(x,f(x)); endfor; % initialize scale numeric u; 10u=3in; % the line F:=F scaled 1u; draw F withcolor blue; % clipping path path cpath; cpath:=(-5,-5)--(5,-5)--(5,5)--(-5,5)--cycle; cpath:=cpath scaled 1u; % clip and save current picture picture pic; clip currentpicture to cpath; pic:=currentpicture; currentpicture:=nullpicture; % erase currentpicture currentpicture:=nullpicture; % draw grid for k=-5u step 1u until 5u: draw (-5u,k)--(5u,k) withcolor 0.85white; draw (k,-5u)--(k,5u) withcolor 0.85white; endfor; % draw axes drawarrow (-5u,0)--(5u,0); drawarrow (0,-5u)--(0,5u); % label axes label.rt(btex $x$ etex, (5.2u,0)); label.top(btex $y$ etex, (0,5.2.u)); label.bot(btex $5$ etex, (5u,0)); label.lft(btex $5$ etex, (0,5u)); % redraw line draw pic; endfig; end.
