Hiding the content (drawing empty boxes?)
by Mojca Miklavec 08 Jul '05

08 Jul '05

Hello, Some TeX challenge (probably not solvable?): for gurus only. Is there a way to somehow \starthidden ... \stophidden, which would leave exactly the same amount of blank space as if the content would be typeset? Adam suggested to use transparent font colour, but this doesn't solve the problem as this won't stop the images, frames and nested \color[red]{font color changing commands} being displayed. I tried to adapt the macro \demobox from the TeXBOOK which processes token by token and draws an empty box instead of that token. It works perfectly as long as there is only plain text between the braces, but as soon there is something more complex, it breaks. This behaviour is probably to be expected, but I have no idea how to let all the commands do what they are expected to do and only prohibit placing any boxes with some content. Thanks, Mojca

How to override a font in a typescript
by Giuseppe Bilotta 08 Jul '05

08 Jul '05

Practical example: when I set up palatino, the typescript file set 'modern' as the typeface (which again tries to load the lm files :)) Assume now that I want to overrule that choice, and only that choice. Can I do this from within my source file? -- Giuseppe "Oblomov" Bilotta

Preliminary support for the Luxi typeface
by Giuseppe Bilotta 08 Jul '05

08 Jul '05

I couldn't find the appropriate typescript definition in ConTeXt, so here's the initial stuff: \starttypescript[mono][luxi][\defaultencoding] \definefontsynonym[Luxi] [\defaultencoding-ul9r8a] [encoding=\defaultencoding] \definefontsynonym[LuxiBold] [\defaultencoding-ul9b8a] [encoding=\defaultencoding] \definefontsynonym[LuxiOblique] [\defaultencoding-ul9ro8a][encoding=\defaultencoding] \definefontsynonym[LuxiBoldOblique] [\defaultencoding-ul9bo8a][encoding=\defaultencoding] \stoptypescript % Maybe should map Slanted, not Italic \starttypescript[mono][luxi][name] \definefontsynonym[Mono][Luxi] \definefontsynonym[MonoBold][LuxiBold] \definefontsynonym[MonoItalic][LuxiOblique] \definefontsynonym[MonoBoldItalic][LuxiBoldOblique] \stoptypescript Of course there's the usual Berry name mapping needed if you only have the LaTeX metrics, which go to the regular expression ul9[rb]o?8[artc] as usual. -- Giuseppe "Oblomov" Bilotta

Why does ConTeXt try to load Latin Modern?
by Giuseppe Bilotta 08 Jul '05

08 Jul '05

I just upgraded my MiKTeX and ConTeXt, and I found out that ConTeXt tries to load Latin Modern regardless of my choice. Example document: """ \setupbodyfont[ppl,rm,12pt]% \starttext Hello, world! \stoptext """ Discarding my \setupbodyfont, ConTeXt tries to load ec-lmr12. Suggestions? -- Giuseppe "Oblomov" Bilotta

bug in mptopdf
by Taco Hoekwater 08 Jul '05

08 Jul '05

Hi Hans, I am afraid there is a bug in the latest mptopdf. It presents itself by spurious spaces in the output for long postscript strings. Here is an example: % uncomment next two lines for viewing in gv(1) %defaultfont := "Times-Roman"; %prologues := 1; beginfig(1); label ("This string wraps to a second line"& " in the metapost output",(origin)); endfig; end. The created pdf document has a space after the p in metapost. The output contains: (This\040string\040wraps\040to\040a\040second\040line\040in\040the\040metap\ ost\040output) cmr10 9.96265 fshow Greetings, Taco

Re: Animations in ConTeXt
by Richard Hirsch 08 Jul '05

08 Jul '05

Richard Rascher-Friesenhausen asked > So again. Is it possible to write something like the above animation packages > in ConTeXt (as a module)? If Acrobat can display them, ConTeXt can generate them. Here is a simple example. \setupoutput [pdf] \setupcolors [state=start] \setupinteraction [state=start] \setuppapersize [S6][S6] %% this is just code to get something to animate \startMPinclusions picture thearrow, thestar; drawarrow (origin--up) scaled 10mm withpen pencircle scaled 3pt withcolor .9 red; setbounds currentpicture to (fullcircle scaled 22mm); thearrow:= currentpicture scaled 5; currentpicture:= nullpicture; for angle=0 step 72 until 359: draw thearrow rotated angle; endfor thestar:= currentpicture; currentpicture:= nullpicture \stopMPinclusions \setupMPvariables [drawstar] [rotation=0] \startuniqueMPgraphic{drawstar}{rotation} draw thestar rotated \MPvar{rotation}; \stopuniqueMPgraphic %% now we define some symbols (the frames of the animated sequence) \def\definestarsymbol#1{% \definesymbol [star #1] [\uniqueMPgraphic{drawstar}{rotation=#1}]} \definestarsymbol{0} \definestarsymbol{6} \definestarsymbol{12} \definestarsymbol{18} \definestarsymbol{24} \definestarsymbol{30} \definestarsymbol{36} \definestarsymbol{42} \definestarsymbol{48} \definestarsymbol{54} \definestarsymbol{60} \definestarsymbol{66} %% the frames are put into a fieldstack \definefieldstack [vortex] [star 0, star 6, star 12, star 18, star 24, star 30, star 36, star 42, star 48, star 54, star 60, star 66] %% and this is the JavaScrip code that displays the frames one by one \startJSpreamble MyField used later var current = 1; var delay = 200; % 200 milliseconds var timer; var running = false; % animation currently not running function Advance_Angle ( ) { this.getField("vortex:"+current).value = "Off"; if (++current > 12) % number of frames { current = 1; } % loop through frames this.getField("vortex:"+current).value = "On"; } \stopJSpreamble %% we want to control the starting and stopping of the animation \startJScode Rotate_Star uses MyField if (running) { try { app.clearInterval(timer); } catch(except) {}; running = false; } else { timer = app.setInterval("Advance_Angle()",delay); running = true; } \stopJScode \starttext \placefigure [here] [fig:animation] {A simple \MetaFun\ animation, click \goto {here} [JS(Rotate_Star)] to start (or stop)} {\fieldstack [vortex]} \stoptext Of course you would want to put the symbol definitions and the definition of the fieldstack into a loop.

I wasn't successful however in putting the symbol list of the fieldstack definition into a loop. Perhaps the ConTeXt gurus can help. Best regards, Richard

literal escape strings in bookmarks
by Stuart Jansen 07 Jul '05

07 Jul '05

Below is a simple example of chapter/section titles containing characters that need to be escaped. Although the page content turns out correctly, the PDF bookmarks contain the literal escape string instead or the desired character. Any ideas how avoid this? I guess this is a bug report. ====== \setupinteraction[state=start] \placebookmarks[chapter,section] \starttext \chapter{test{\char`_}chapter} The underscore character needs to be escaped in certain situations. \chapter{start{\char124}stop} So does the pipe symbol. \chapter{foo} \section{bar} How can I avoid literals escape strings in bookmarks? \stoptext ====== -- Stuart Jansen <sjansen(a)gurulabs.com> Guru Labs, L.C.

how to create many blank pages
by Ciro Soto 07 Jul '05

07 Jul '05

I need to create a book with many blank pages (with its header & footer texts). Is there any easy way to create, say, 300 blank pages one after the other, wihout using \page 300 times? I guess what I need is to know how to loop within context. thank you Ciro
