Putting things over a figure
by nico 23 Apr '06

23 Apr '06

Hello, I need a mechanism with which I can put several things (text, image) at a precise position over a figure. The position is expressed in percentage (x,y) of the figure dimensions. The lower-left corner is (0,0). I did the following that works for my own needs, but maybe a higher level interface (layer?) could do the same. Any comment or improvement is welcome. \newdimen\overfigwd \newdimen\overfight % Put the figure and define the x/y percentage factor for the calspairs. \def\startoverfig {\dodoubleempty\dostartoverfig} \def\dostartoverfig[#1][#2]% {\bgroup \setbox\scratchbox\hbox{\externalfigure[#1][#2]}% \overfigwd=\wd\scratchbox \overfight=\ht\scratchbox \setuppositioning[unit=pt, xfactor=\withoutpt\the\dimexpr(\overfigwd/100), yfactor=\withoutpt\the\dimexpr(\overfight/100)]% \startpositioning \position(0,0){\box\scratchbox}} \def\stopoverfig {\stoppositioning\egroup} % Put (centered) at the position (x%,y%) on the figure. % The lower-left corner is (0,0) \def\calspair(#1,#2)#3% {\setbox0\hbox{#3}% \position[xoffset=\dimexpr(-\wd0/2), yoffset=\dimexpr(-\ht0/2)](#1,{\numexpr(100-#2)}){#3}} %% \setupcolors[state=start] \starttext \startoverfig[duck-small] \calspair(0,0){A} \calspair(100,100){B} \stopoverfig \startoverfig[duck-small][width=4cm,frame=on] \calspair(0,0){A} \calspair(100,100){B} \calspair(50,50){\framed[background=color,backgroundcolor=green]{Hello}} \stopoverfig \startoverfig[unknown] \calspair(30,0){A} \calspair(100,100){B} \stopoverfig \stoptext Regards, BG

2c considerations about win installer
by andrea valle 23 Apr '06

23 Apr '06

Dear all, I'm using conTeXt to create automatic documentation about sound classification. The idea is that starting from an html file collecting infos about sounds my program can generate some schematic images using R and POV-Ray and to create a conTeXt file including both images and textual information. Now, I'd like to share this work with my students. I'm on macosx, they're typically on win. My program is in python so it's cross-platform, so no problem. Obviously they can annotate sounds, generate images and include them manually in a MS word file. But I'd prefer that they compile the conTeXt file. On two win machines I tried to install conTeXt using the complete package (shipped with Scite: nice). I had always (different) troubles (on each machine) with environment variable (e.g. for Perl): actually I'm not able to run conTeXt. Hacking a bit, eventually asking the list, I think I will solve the problem. But I don't think that my students can do, as I suspect that they probably not even know what is PATH. And I cannot help them on each installation. So, more generally, I was asking myself if it would not be possible (and better) to have an .exe installer as usual happens in win, including Perl, maybe Ruby (+ or- 20 Mb doesn't change too much). Double click, and it set ups all the installation parameters. A completely autonomous installer would allow many people to try, use and get fond conTeXt (and maybe to leave Word) without having to struggle with problems which typically lead people to leave out. It seems to me that a similar installer would be a refinement in the spirit of the actual mswincontext distro. At the end, it's not that far form Gerben's distro on macosx. It does everything for me... Or maybe am I missing something?

Feature request: Creating tables from (tab-separated) values
by Mojca Miklavec 23 Apr '06

23 Apr '06

Hello, This idea described below was partially inspired by "gnuplot contemptations", but mainly because writing tables with both LaTeX & ConTeXt is too complex in most cases. Natural tables are great since they offer anough flexibility to do "just about anything" with tables, but many tables are still simple "m values in n rows" and for those it's an annoying task to write those "\NC"s, "\eTR\bTR"s, ... even if it's just a matter of writing a script to transform the values to a suitable form. Christopher Creutzig has sent an interesting solution to the mailing list some time ago (see http://wiki.contextgarden.net/TABLE#Creating_tables_from_CSV_data_.28Comma_…) and since then I've been thinking about a similar, slightly more powerful solution which could make table-typesetiting easier. I don't have enough skills to implement it, but here are some properties listed that such a solution should have. In case anyone finds this little project doable ... It would solve quite some headaches. - [very important] a possibility to define own macros, so that it would be easy to print any type of tables (natural tables, TaBlEs, ... or whatever form that could possibly come to someone's mind); for example \def\MyDef#1#2{\bTR\bTD#1\eTD\bTD#2\eTD\eTR}; the "machinery behind" would only have to "feed" these macros properly according - [important] possible to separate the data with different characters: tab, comma, multiple spaces, ampersand (&), ... - [very useful] a possibility to read the data from a block (\start...\stop...) or from a file; it would be handly to be able to use the same data file for making a plot and for printing the data into a table - [useful] possibility to ignore lines starting with '#' (optional; usually these are comments) - [not crucial] if comma (,) is separating the data, a possibility to escape it - [useful] a possibility to select which rows (columns) to print (for example rows "1-3,8-last" or "even", ...) - [optional, but still useful] replacing decimal points with commas - [optional] if the table was supposed to have 4 colums and only 2 are available, ignore/fill with empty arguments (don't panic with unnecessary errors) - [with luaTeX in mind] calculating sums of rows & columns & other Excel-like calculations & references accross tables ;) - well, that one wasn't meant seriously. Thanks a lot, Mojca

Re: [NTG-context] Fieldstack Walk
by Michal Kvasnička 22 Apr '06

22 Apr '06

Good afternoon. Many thanks, this solves the problem -- at least partially. The frames are `walking' now, but new problems appeared. I found that when I set `clickin=...', it is set it automatically to `clickout' as well, so one mouse click runs the JavaScript code twice. So I've set it this way: \definefieldstack[fgolds2] [sgolds1,sgolds2a,sgolds2b,sgolds2c,sgolds2d,sgolds2] [frame=off,option=,clickout=JS(Walk_Field{fgolds3}),clickin=] It's better, but I found that now frames are walking in a strange order. It is rather puzzling, since when it is invoked by \goto{...}[JS(...)], it works well. Moreover, it does different things at AdobeReader 7.x under Linux, and Acrobat 4.x under Windoze. Can you help me to solve it? Many thanks once more. M.K.

Document Structuring

Hi all, I have a document with the following structure: \starttext \startstandardmakeup \maketitle \stopstandardmakeup \setupheadertexts[][{\sl \getmarking[chapter]}] \startfrontmatter \setuppagenumbering[conversion=romannumerals] \setuppagenumber[number=1] \chapter{Table des matières} \placecontent[alternative=c,criterium=all,interaction=all] \chapter{Liste des figures} \placelistoffigures[alternative=c,criterium=all,interaction=all] \component src/chapters/c_intro \stopfrontmatter \setupheadertexts[][{\sl \getmarking[section]}][{\sl \getmarking[chapter]}][] \startbodymatter \part{test I} \component src/chapters/c_simulation \component src/chapters/c_locomotion_robotique \component src/chapters/c_environnement \part{test II} \component src/chapters/c_locomotion_robot_serpent \component src/chapters/c_tda \part{test III} \component src/chapters/c_modelisation \component src/chapters/c_commande \part{test IV} \component src/chapters/c_conclusion % \component src/chapters/c_chap1 % \component src/chapters/c_chap2 \stopbodymatter \startappendices \chapter{test A} \chapter{test B} \stopappendices \setupheadertexts[][{\sl \getmarking[chapter]}] \startbackmatter \chapter{Bibliographie} \placepublications[criterium=all,interaction=all] \stopbackmatter \stoptext The normal behavior of this structure is for each "part" to reinit pages, chapters and figures numbering. My questions are: 1. How to change this behavior to obtain a continuous pages, chapters ... numbering ? 2. How to obtain a separated title page at the beginning of each parts (with doublesided mngt)? 3. How to obtain (I,II,III,IV) for part numbering ? Cheers, Renaud

First space shown in a referenced itemize head
by nico 22 Apr '06

22 Apr '06

Hello, When a reference is set to \head, a space after the square brackets appears in the output. Shouldn't it be ignored? Applying a reference to \item does not show the problem. Besides, what is the best way to put item or head text in square brackets? Using \relax works but I'm not sure if it's the recommended method. Here is an example: \starttext \startitemize[n][headstyle=bold] \head Head1 \par Body1 \head Head2 \par Body2 \head[u]Head3 \par Body3 \head[v] Head4 \par Body4 \head[v] Head4 \par Body4 \head\relax[Head in brackets] \par Body5 \head\relax [Head in brackets] \par Body6 \item Item1 \item Item2 \item[w]Item3 \item[x] Item4 \item[y] Item4 \item\relax[Item in bracket] \item\relax [Item in bracket] \stopitemize \stoptext Regards, BG

linenotes/footnotes
by Thomas A.Schmitz 22 Apr '06

22 Apr '06

Hi gang, I played arund some with the linenotes mechanism provided in core- lnt.tex and an example provided by Hans about a year ago. On p. 398-399 of the TeXbook, Knuth shows how footnotes can be set as ordinary paragraphs in plain TeX, with no paragraph breaks between single notes. In the ConTeXt mechanism, I see only the possibility to determine the number of columns on which notes will be set. Can Knuth's solution somehow be hooked into the ConTeXt notes? Best Thomas
