3D MetaPost tool:3DLDF
by Tobias Burnus 13 Jan '05

Hi, 3DLDF might be interesting to some of you. I have not tested it, but it seems to use a similar language to MetaPost (but with 3D coordinates) and generates real MetaPost. http://www.gnu.org/software/3dldf/ | My primary purpose in writing 3DLDF was to make it possible to use MetaPost for | three-dimensional drawing. I've always enjoyed using MetaPost, and thought it was | a shame that I could only use it for making two-dimensional drawings. 3DLDF is a | front-end that operates on three-dimensional data, performs the necessary | calculations for the projection onto two dimensions, and writes its output in the form | of MetaPost code. | | While 3DLDF's data types and operations are modelled on those of Metafont and | MetaPost, and while the only form of output 3DLDF currently produces is MetaPost | code, it is nonetheless not in principle tied to MetaPost. It could be modified to | produce PostScript code directly, or output in other formats. It would also be possible | to modify 3DLDF so that it could be used for creating graphics interactively on a | terminal, by means of an appropriate interface to the computer's graphics hardware.

This solution worked for me. I have added it to Sample Macros in the Wiki. Thanks, Duncan

ConTeXt dont work with fonts after last miktex update
by matthias.c.schmidt＠t-online.de 12 Jan '05

12 Jan '05

After the last update ConTeXt has problems with fonts unter miktex. from the log: [1.1{original-empty.map}{texnansiOSFSC-adobe-cronospro.map Warning: pdfetex (file texnansiOSFSC-adobe-cronospro.map): invalid entry for `texnansiOSFSC-raw-CronosPro-Bold': invalid font file name the entry in the map-file: texnansiOSFSC-raw-CronosPro-Bold 4 < CronosPro-Bold.pfb texnansiOSFSC.enc Before update all worked fine. Nothing has changed. The .enc files are under fonts/enc and in the miktex.ini the path is set on it (under pdfetex). ConTeXt/pdfetex don't find any font file (but under LaTeX all is o.k.). I red that there are have to changed any variables, but I don't know how I have to do this under miktex (miktex.ini looks well for paths). Why it doesn't work now? Thanks in advance, Matthias

\godown to an absolute position
by Duncan Hothersall 11 Jan '05

11 Jan '05

Hello. I have a style request that I haven't come across before and don't know how to handle in ConTeXt. I need the first line of text following a chapter title to always start 15 picas from the top edge of the text area. In other words, no matter how little space the title takes up, the first line after it should always start at the same vertical point. Something like -- \chapter{Chapter title} \godown[to=15pc] Start of the text of the chapter... -- would be ideal, but of course \godown starts from the current point and doesn't offer a to= option! I'm not sure that layers are the answer because as soon as I have moved down I'm into the running text of the chapter. Can anyone help? Thanks very much. Duncan

XML question regarding special characters
by Zeljko Vrba 11 Jan '05

11 Jan '05

Hi! I'm trying to design a "universal" markup that will be easy to convert both to PDF and HTML. I've come to code and equations. I don't want to use MathML and I want to output (and use in my documents!) verbatim TeX code of equations to HTML. What worries me is the following: I want to be able to write and run through Context XML processing: <formula label="fm:whatever> x^{2} < y </formula> or, for typesetting computer programs: <code> if((x&y) >= 3) { do_something(); } </code> (this would translate to \starttyping\stoptyping) How do I define XML environments that can handle XML special characters (<>&, etc., I don't know all of them..) gracefully? (i.e. so that I don't have to type <code> if((x&y) >= 3) </code> and similar for formulas) Thanks!

recursion/loop with counter?
by Henning Hraban Ramm 10 Jan '05

10 Jan '05

Hello again! In a form I need a lot of empty, but numbered fields. Can I access the counter of \dorecurse somehow, or is there another loop command? e.g. \dorecurse{20}{\bTR \bTD \LoopCounter bottles of beer \eTD \bTD{\strut} \eTD \eTR} or \dorecurse{20}{\definefield[Fld\LoopCounter][line][MySetup][]\field[Fld\ LoopCounter]} Grüßlis vom Hraban! --- http://www.fiee.net/texnique/ http://contextgarden.net

All, I have: \setupurl [style=bold] \useURL[craig][http://online.redwoods.cc.ca.us/instruct/darnold/CalcProj/Fal l98/CraigA/project3.htm] \from[craig] But it runs off my slide before wrapping. I'd like to break this up so it is on two lines and centered. Any suggestions?

Context index and sorting question
by sjoerd siebinga 10 Jan '05

10 Jan '05

Hi all, I am currently working on a dictionary with multiple indices of older language stages like, Old English, Old Norse, Greec, Sanskrit, Hittite, etc. Most of these languages have different characters, accents and sorting rules than English. In enco-ini.tex I found the \definesortkey command, but it is not entirely clear to me how I could use this command for the individual indices instead of for the overall language (in my case english). Or even if this is possible at all? Could someone tell me how I can use the \definesortkey command or for that matter any other ConTeXt mechanism to define sortrules for individual indices? Regards Sjoerd PS why does Texutil strip accents \' \~ \` \" \^ but not \= ?

layers and papersize
by Tom Fossen 10 Jan '05

10 Jan '05

This is probably a beginners question. While trying to understand the layer-mechanism I made a drawing which is meant as a background for a schedule in a magazine. I add the information within this drawing using the 'register' option I found on page 263 of the Metafun manual. Here is the example in a minimal form: \starttext \definelayer[rooster] \startuseMPgraphic{list} path p, s ; p := unitsquare scaled 3cm superellipsed 0.84 ; s := flex ((2.5cm,3.0cm), (10.0cm,3.0cm), (6.5cm,-0.5cm)) ; draw p withpen pencircle scaled 5pt withcolor .625white ; draw s withpen pencircle scaled 3pt withcolor .625white ; register ("da",2.4cm,2.4cm,(.3cm,2.8cm)) ; register ("name",5.6cm,0.6cm,(5.4cm,3.5cm)) ; register ("who",6cm,3cm,(3.4cm,2.8cm)) ; register("color",1.5cm,0.5cm,(7.6cm,-0.6cm)) ; \stopuseMPgraphic \setMPlayer[rooster][da]{\framed [width=\MPlayerwidth,height=\MPlayerheight,align=right] {pos 1}} \setPlayer[rooster][name]{\framed [ [width=\MPlayerwidth,height=\MPlayerheight] {pos 2}} \setMPlayer[rooster][who]{\framed [width=\MPlayerwidth,height=\MPlayerheight,align=right] {pos 3}} \setMPlayer[rooster][color]{\framed [width=\MPlayerwidth,height=\MPlayerheight] {pos 4}} \getMPlayer[rooster] {\useMPgraphic{list}} \stoptext This works for the standard papersize. But I want this to work in a magazine on A5. So I add: \setuppapersize [A5][A4] \setuparranging [2UP,rotated,doublesided] \setuppagenumbering[alternative=doublesided] \setuplayout[margin=0pt,width=middle] followed by the fragment above. But now all of the texts ("pos x") end up somewhere in the left corner of the page. Only the drawing is on its right place. I tried to experiment with adding 'position= on' or 'off' to the 'definelayer' command. No difference. Where are the misunderstandings on my side? tom fossen
