placing movies
by Hans van der Meer 18 Sep '07

18 Sep '07

Placing a movie with the following code places the static overlay a bit (too far) to the right, spilling it on the right side out of the frame: \useexternalrendering[sharkfilm][video/quicktime][shark.mp4] \defineoverlay [shark][{\externalfigure[shark-film][width=\overlaywidth,type=jpg]}] \starttext ... \midaligned{%\framed[offset=0pt, strut=no, background= {foreground,shark}]% {\placerenderingwindow[movie][sharkfilm]}}% Is there some spurious space in the code? Perhaps a missing % at the end of a line? I could not spot the culprit in the code, but I might have been looking in the wrong places. Then as an additional question: When running the movie a thin white frame line appears around it. I find it annoying but did not find out how to get rid of it. Nor have I been able to change the background color locally (when leaving out the external figure in the overlay) or get rid of the text "Screen" that appears. I found a macro \setuprenderingwindow but did not find out about the settings it understands. Can someone enlighten me? Hans van der Meer

section title: alignment
by Jörg Hagmann 18 Sep '07

18 Sep '07

Dear list members, My section titles have a gray background of textwidth, as follows: \def\SectionCommand#1#2{\framed[frame=off,width=\textwidth,% align=right,background=color,backgroundcolor=lightgray]{#1\quad#2}} \setuphead[section][command=\SectionCommand,numbercolor=red] That works, except when section titles are longer than textwidth: in that case, the second line is aligned with the number, not the text. How can I get correct alignment? I tried to include \starttabulate \NC #1 \NC #2 \NC\NR \stoptabulate in SectionCommand, but then the background extends too much above and below. I'm sure there is an easy solution? Thanks a lot, Jörg Minimal example: \setupcolors[state=start] \def\SectionCommand#1#2{\framed[frame=off,width=\textwidth,% align=right,background=color,backgroundcolor=lightgray]{#1\quad#2}} \setuphead[section][command=\SectionCommand,numbercolor=red] \starttext \section{A very long title, longer than the width of the text and therefore needing a second line} \stoptext

But something I played with once upon a time for much the same purpose. You should take a look at Jonathan Fine's TeX daemon project texd (http://sourceforge.net/projects/texd) if you haven't already - it runs as a pipe (unix) and only loads formats once; it would take a little bit work to get it going reliably with ConTeXt, especially to do so in a way that is easily updated when a new ConTeXt is released, and I'm not sure if Jonathan is still actively working on the project. But it demonstrates an effective approach, which works with Plain (and LaTeX I think). Duncan

Interactive slides---hidden field on every page
by Michal Kvasnička 17 Sep '07

17 Sep '07

Good morning or whatever you have now in Europe. It seems that my mail have come to the list, so I dare to repost it: I'm preparing my slides. Every slide is divided to three parts (backgrounds): text, header, and bottom. I've got the navigation buttons in the bottom. Now I'd like to add one more button that would open a field on the current page---a field containing the list of content. I'd like it to go to the \Topic I want to discuss and disappear. I tried this: \definefield[Content][check][HelpSetup][content][content] \setupfields[reset] \setupfield[HelpSetup] [width=fit,height=fit,frame=off,option={readonly,hidden}] % \definesymbol[content][\SomeContentText] \def\SomeContentText{% \startframedtext [width=\textwidth, height=fit, frame=on, background=color, backgroundcolor=tmava,framecolor=svetla]% \placecontent} \stopframedtext } % \setupbackgrounds [text] [%backgroundoffset=10pt,%.5cm, background={contentmenu,nextpage}] % \defineoverlay [ContentOnOff] [{\goto{\framed[width=\overlaywidth,height=\overlayheight,frame=off]{\hss}}% [JS(Toggle_Hide{Content})]}]%\overlaybutton{JS(Toggle_Hide{Content})}] % \startinteractionmenu[bottom] \setupinteraction [color=svetla, contrastcolor=black] \hbox to 600pt{% \raise0.4em\hbox{% \framed[width=3em, height=0.7em, frame=off, background={PageCounter,ContentOnOff}]{}} \hss \interactionbuttons[frame=off, width=8em] [firstpage, previouspage,nextpage, lastpage, PreviousJump,NextJump]% \hbox to 1cm{\hss}% \hbox to 44mm{% \interactionbuttons[frame=off][CloseDocument]\hss}% } However, it doesn't work: 1. The list of content is placed only on one page, not at all of them as I would like. 2. The field supposed to show/hide it isn't clickable---it isn't interactive, and does nothing. 3. I use \Topic and \Subject as heads, and I don't know how to put them to the list of content. Can you possibly help me to solve this problem? Sincerely yours Michal Kvasnicka

Greek in luatex
by Thomas A. Schmitz 17 Sep '07

17 Sep '07

Hi all, I've been experimenting with my Greek stuff in luatex, and I think I'm making nice progress. Things pretty much work with Unicode input, and as soon as the kerning problem is solved, I'm very optimistic. Two questions came up for me; I assume the answers are straightforward, but couldn't find anything: 1. How can I remap single characters? Let's say that we have a Unicode character in the input stream that maps to 0x03c3, but I want it remapped to 0x3f2, how can this be achieved? 2. Similarly: if I want to support the legacy input method babel, I need to remap the input stream to the Greek characters (question 1) and also need to feed the font some ligature rules, such as: the combination >a needs to be combined into the character 0x1f00. What would be the syntax and the way to do this? All best Thomas

Recommendations for Speed?
by Duane Johnson 17 Sep '07

17 Sep '07

Hello, I've been perusing the list archives for a couple of days now, and reading up on articles (such as Hans' regarding optimizing in TeX and eTeX) to find guidance on a handful of decisions. Our company makes a web-based publishing solution called MemoryPress.com that uses conTeXt for on-demand creation of PDFs which are then converted to jpeg format for display in a web browser. We are currently looking into ways to speed things up and since many of you are far more qualified than I am in this area, I wondered if you might advise me on the following: 1. Is there a way to keep TeX in-memory (i.e. as a server or daemon process) so that it doesn't have to load and reload fonts and the environment? Our system makes repeated requests for typeset documents and we are wondering if there's a way to remove the overhead of re-running pdftex. 2. Among the many different command-line TeX options, what might optimize for speed? I've done some rudimentary benchmarking and found that executing etex (without conTeXt) is much faster than texexec, and wondered if there is any advice in this area. Is there any way to shave off some of the overhead of using conTeXt? 3. I've noticed that there is some kind of caching going on (tui/tuo files?) that helps speed things up after the first run. How can I best take advantage of this facility? What kinds of things will require TeX to start from scratch, vs. use some or all of this cached information? 4. Are there any other areas I should consider when looking for ways to use TeX as an on-demand typesetting engine? Thank you, Duane Johnson Programming Manager FamilyLearn

XeTeX after ctxtools in MacTeX was: xetex and external pdf stretching

Re: [NTG-context] need help for the installation of luatools
by Dalyoung Jeong 16 Sep '07

16 Sep '07

Dear Thomas, I found the folder /usr/local/Build/powerpc/TeXLive.2006. I remembered that I have tried to install TeX using the source before. When I open terminal, .luatex in not implemented yet and "texexec -- make --all --pdftex" run without any errors. %%%%%%%%%%%%%%%%% texexec --make --all --pdftex TeXExec | using search method 'kpsewhich' TeXExec | updating file database mktexlsr: Updating /usr/local/gwTeX/texmf/ls-R... mktexlsr: Updating /usr/local/gwTeX/texmf.gwtex/ls-R... ... mktexlsr: Done. TeXExec | using tex engine pdftex TeXExec | using tex format path /Users/dalyoung/Library/texmf/web2c/ pdftex TeXExec | generating tex format cont-en This is pdfTeX, Version 3.141592-1.40.3 (Web2C 7.5.6) (INITEX) (/usr/local/gwTeX/texmf.pkgs/web2c/natural.tcx) ... %%%%%%%%%%% As you see in the above output, it uses the searching method 'kpsewhich' and '/usr/local/gwTeX/texmf.pkgs/web2c/natural.tcx' But after running 'source ~/.luatex', it used the same searaching path but different path for format and engine paths as following even though I removed /usr/local/Build folder. However, to run 'luatools --generate', I need to run .luatex. Still, I have a problem in 'luatools --ini --compile...'. %%%%%%%%%%%%%%% texexec --make --all --pdftex TeXExec | using search method 'kpsewhich' TeXExec | updating file database ...

I attached .luatex file which shows the TDS in my mac. By the way, what is 'whence'? It is a unknown cmd in my machine. and how to remove '/usr/local/Build/...' from the engine path? Thank you for your help. Best regards, Dalyoung

Windows Installer for MsWinContext
by Vyatcheslav Yatskovsky 16 Sep '07

16 Sep '07

Hello, I'm back with my idea of installer for mswincontext distribution. I successfully use my local (post-install) version , which simply sets env. vars, but I feel there is need for more. Anticipating new mswincontext build, I can implement the installer for it using free Inno Setup software. The controversy is about setup file content. I see it as whole mswincontext, because it is declared as minimal distribution (so, nothing can be thrown away). However, I was suggested on this list to make some parts downloadable on demand, so I need to ask: what parts to make? In general, I believe that if classical Windows installer for ConTeXt were available, it would gain more popularity and appreciation. Of course, I'd like to hear from Hans and Taco what they think about it, and whether they dare to facilitate this. Best, Vyatcheslav Yatskovsky
