With the change to [strut=no,offset=overlay] the result looks a litlebit better. Though there is still whitespace to the left and to the right. \definelayer[Kontaktdaten][x=50mm,y=150mm,width=30mm,height=40mm,state=start] % size is ignored! \setupbackgrounds[paper][setups=ALayer,background=Kontaktdaten,state=start] \starttext \strut \setlayerframed[Kontaktdaten][frame=on,hoffset=0mm,voffset=0mm][strut=no,offset=overlay] % <==== look here { {\externalfigure[jkopp][width=30mm][height=40mm]} } \stoptext Look here: http://www.imagebanana.com/view/ksjzn63e/FotoinLayer.png Janis Am 14.10.2011 00:22, schrieb Mojca Miklavec: >> \setlayerframed[Kontaktdaten][frame=on,hoffset=0mm,voffset=0mm,align=left] > strut=no,offset=overlay > > align=left doesn't do what you want it to do. > > Mojca >

Step by Step I'm going forward. This shuld be the result, when I am ready: http://www.imagebanana.com/view/f4o3un2c/Entwurffriends.png At the moment I try to get the foto into a layer. Though the layer is definded as 30x40mm and the foto as well - the foto does not fit into the layer: the layer is a bit bigger. See here: http://www.imagebanana.com/view/29611n9s/FotoinLayer.png And here is what I did: \definelayer[Kontaktdaten][x=50mm,y=150mm,width=30mm,height=40mm,state=start] % size is ignored! \setupbackgrounds[paper][setups=ALayer,background=Kontaktdaten,state=start] \starttext \strut \setlayerframed[Kontaktdaten][frame=on,hoffset=0mm,voffset=0mm,align=left] { {\externalfigure[jkopp][width=30mm][height=40mm]} } \stoptext How can I fit the foto exactly into the layer?

missing html entities in latest ConTeXt
by Mojca Miklavec 13 Oct '11

13 Oct '11

When processing HTML with TeX Live 2011, all the entities are nicely converted into corresponding characters. With latest version of ConTeXt I get literal "le" instead of ≤ for ≤ or "hellip" instead of ... for … I will try to send a minimal version (the one I sent with MathJax can probably serve as a good starting point).

bug: wrong subject name in headertext
by Mojca Miklavec 13 Oct '11

13 Oct '11

Hello, the following example might not be the most minimal possible example, but I hope that it is short enough. I'm using \setupheadertexts [] [subject] to print subject into header, but the headers are screwed up in some very weird way. My real document behaves differently that this minimal example, but even here one can notice that headers say: - This is first heading - This is fourth heading - This is second heading - This is fourth heading instead of getting the second heading. Does anyone have any idea what is going on? Thank you, Mojca \startbuffer[test1] <html> <body> <h1>This is first heading</h1> <p>some text</p> <h1>This is second heading</h1> <p>some text</p> </body> </html> \stopbuffer \startbuffer[test2] <html> <body> <h1>This is third heading</h1> <p>some text</p> <h1>This is fourth heading</h1> <p>some text</p> </body> </html> \stopbuffer \startxmlsetups all:html \xmlsetsetup{main}{h1}{*} \stopxmlsetups \startxmlsetups h1 \subject{\ignorespaces\xmlflush{#1}} \stopxmlsetups \xmlregistersetup{all:html} \setuphead [subject] [style=\bfa, page=odd] \setupheadertexts [] [subject] \starttext I have some text first \xmlprocessbuffer{main}{test1}{} \xmlprocessbuffer{main}{test2}{} \stoptext

Interpreting MathJax HTML in MKIV
by Mojca Miklavec 13 Oct '11

13 Oct '11

Hello, I would like to manually create some HTML which would be displayed nicely in both HTML and PDF (using MKIV for conversion from HTML). To a certain degree I'm able to fake mathematics with <span class="math"><span class="letter">ax</span><sup>2</sup> + <span class="letter">bx</span> + <span class="letter">c</span> = 0</span> where <span class="math"> signals TeX to use \mathematics{...} and <span class="letter"> signals web browser that the letter has to be displayed in italic (I could use class="math", but this would also make numbers italic). But this is very cumbersome to write. MathJax offers an excellent way to enter math formulas in an easy way (see attached HTML), but I'm not sure how I could convince the XML parser to treat contents literally. Any ideas? Thank you very much, Mojca

nice friends-book with ConText
by Jan Heinen 13 Oct '11

13 Oct '11

Hello, I hope the answer is easier than the question :-) I am a ConText-Newby and am struggeling with the huge amount of ConText-commands. I want to make a little book with infos and fotos of our friends - and I am afraid, the nice layout I have in mind is to complicated or impossible with ConText - at least for me. The book will have 40 pages and every page with the same layout. I have posted the layout I want to use as a .png to http://www.imagebanana.com/view/f4o3un2c/Entwurffriends.png Which ConText-commands do I need for this layout? I tried \inmargin - without success. \definelayer and \setlayerframed worked (a littlebit) - though the running text (beneath the headline) runs through the layer. What seems the easiest way? layers, columns, ? Maybe someone here has a little example which I can finetune. Which hints can be given? I would be very happy about a rough structure of the context-code - I think then I am able to do the finetuning with the manuals. I am working with Linux - so Indesign is no alternative for me :-) Regards Jannis

Error in simpleslides style Swoosh
by Marco 13 Oct '11

13 Oct '11

Hi, the presentation template “Swoosh” behaves weird and triggers an error. • Use the example file generic-talk-15min-45min.tex • Comment “style=BigNumber,” • Uncomment “style=Swoosh,” The log file is attached. Workaround: First processing the file using another style, then processing using “Swoosh” does not trigger the error. Regards Marco Patzer

Hello, in some rare circumstances the enabled italic correction (\setupitaliccorrection[always]) cause the following error: /tex/texmf-context/tex/context/base/typo-itc.lua:99: attempt to index local 'cd' (a nil value) In needed I will try to make a minimal example. I’ve asked it already, bun since I got no answer … Would it be possible to expand the the cross referencing mechanism, so that it would be possible to store the component files in a subfolder? Here is a test: http://www.ntg.nl/pipermail/ntg-context/2011/062335.html Thanks in advance Andreas

Setting style and color attributes of label in metapost
by Aditya Mahajan 13 Oct '11

13 Oct '11

I am writing a module which uses metapost in the background for drawing. I wanted to create an interface for setting the style and color of metapost labels but using \doset...attributes is not working. Here is an example: \definenamespace [test] [style=yes, name=test, command=yes, setup=yes] \definetest [blue] [color=blue, text=Blue] \definetest [two] [blue] [style=\bold, text=Two] \starttext \edef\currenttest{two} \startMPdrawing label.lft(\sometxt{\dosettestattributes{style}{color} \testparameter{text}}, (0,0)) ; \stopMPdrawing \edef\currenttest{blue} \startMPdrawing label.lft(\sometxt{\dosettestattributes{color}{style} \testparameter{text}}, (2cm,0)) ; \stopMPdrawing \MPdrawingdonetrue\getMPdrawing \stoptext Notice that the first label has the same style as the last label. This is happening because \doset..attributes is defined as an unexpandable macro. I can get around this by setting the value of \currenttest inside the \sometxt{...} argument. Something like: \def\dosometxt#1#2% {\normaldosometxt{#1}% {\def\noexpand\letterbackslash currenttest{\currenttest #2}}} Surely, there should be a more direct way of achieving this? Aditya

Plotting a graph of a function f, like f(x) = e^x, with MetaPost
by Paul Menzel 13 Oct '11

13 Oct '11

Dear ConTeXt folks, I finally chose MetaPost/MetaFun [1] because of the native integration with ConTeXt and hopefully easy font handling. I want to use that throughout my document. Of course I hit the first problem. Wanting to draw a “simple” function f like f(x) = e^x, seems hard to accomplish. I guess I should stress that MetaPost does not have a high accuracy so it might not be the best solution [5]. There seem to be quite a lot of solutions (mostly macros) on the Web for this problem so I am wondering if one of them is integrated in MetaFun. Here are some of my findings. 1. Reading about the graph package by John D. Hobby [2] and which is also included in ConTeXt [3]. Especially I liked the automatic coordinate systems. The package seems to only be able to plot graphs with data points saved in files. So one solution would be to manually create data files with data points of the relevant function. 2. There is an example in the Drexel Physics Wiki [4]. 3. Anthony Phan has also created some macros in his `mps` [5 (currently not accessible)]. 4. André Heck uses the macro packages `courbes` and `grille` from Jean-Michel Sarlat to show some nice examples in his tutorial »Learning Metapost by Doing« [6]. So what do you suggest? Thanks, Paul [1] http://www.ntg.nl/pipermail/ntg-context/2011/058527.html [2] http://tug.org/docs/metapost/mpgraph.pdf [3] http://wiki.contextgarden.net/Metapost [4] http://einstein.drexel.edu/liki/index.php/Metapost#Graphing_Functions [5] http://www-math.univ-poitiers.fr/~phan/downloads/metapost/statsman.pdf [6] http://staff.science.uva.nl/~heck/Courses/mptut.pdf
