url compared to hyperref
by Marko Schütz 20 Oct '06

20 Oct '06

When using hyperref and displaying the resulting PDF in xpdf, I see links that are active. I tried achieving the same with useURL, url and goto, but the resulting links aren't active in xpdf. I have to use acroread to have active links. Is there a compelling reason for this behavior? Thanks, Marko

Any idea about copy or clone fieldstack?
by Zhichu Chen 20 Oct '06

20 Oct '06

Hello everyone, I want to display dynamic system time on each page of my presentation. Displaying system time can be manipulated by JavaScript but, a field can be shown only once. So I used clone field and it works very well for me. But when I want to change the font (xxx presents the variable that gets the field): ------------------------------------------------ xxx.textFont = font.LucidaBright ; ------------------------------------------------ it can be compiled successfully, but when I open it with acrobat reader, there are many errors from javascript console. So I think that JS don't know the font, and I don't know how to embed the font into pdf file and make JS knows it. Then I turned to use field stacks. I use MetaPost to draw some needles and use JS to set_Field the fieldstack to the correct frame. But when I want to display the second clock, it seems that I should write another JS code to control the other fieldstack. So is there some command that clones the fieldstack just like \copyfield? Or how to assign the font of the field as I like? Thank you. -- Sincerely yours, Chen ---------------------------------------------------------------- Zhi-chu Chen | Shanghai Synchrotron Radiation Facility No. 2019 | Jialuo Rd. | Jiading | Shanghai | P.R.

Lists
by Ángel Luis García Fernández 19 Oct '06

19 Oct '06

Hi all, I'm new to the list, although I'm working with ConTeXt since last spring. I have been trying to find everything I need on my own, but there is a problem I cannot solve at this moment. The thing is I'm writing my PhD thesis, and I would like to have not only a "List of figures", but also a "List of algorithms" and a "List of formulas". Is there a simple way to create a "\placeXXX" command similar to the \placefigure and a "\placelistofXXXX" similar to the "\placelistoffigures"? I suppose they can be programmed, but I'd rather not to start learning how to program in ConTeXt right now. Thanks in advance Angel-Luis Garcia

I said: > Where did I go wrong? I'm sure there is an easy way to do this. And yes there is! The easy way is to use the new beta, which works. Sorry for the noise. Duncan

Giving a float its own number
by Duncan Hothersall 19 Oct '06

19 Oct '06

I have a book with parts and chapters; figures in the chapters are numbered 1.1, 2.1 etc. but sometimes a part has a figure in it as well, before the chapters start. The desired numbering for such figures is to follow the Part numbers, and be in capitalised roman numerals (in other words, Figure II would be the figure in the intro of Part 2). So I define a new clone of figure called Partfigure, and give it the necessary setups to make the numbering come out in cap roman; and I thought the easiest way of managing the number itself would be just to increment it each time \part is called. (Not every part has a figure.) But I can't seem to get the number to come out when I place the figure. Minimal example below (I have culled the actual \parts and just put in two increments, but the effect is the same). ---- \definefloat[Partfigure][figure]\definenumber[TrackingPartfigurenumber] \setuplabeltext[en][Partfigure=Figure ] \setupnumber[Partfigure][number=TrackingPartfigurenumber,conversion=Romannumerals,way=bytext] \setupcaption[Partfigure][style=\bf,numberstyle=\bf,headstyle=\it,align=middle,location=bottom] \starttext \incrementnumber[TrackingPartfigurenumber] \incrementnumber[TrackingPartfigurenumber] TrackingPartfigurenumber now equals \rawnumber[TrackingPartfigurenumber], which will display as \convertednumber[TrackingPartfigurenumber]. But it doesn't get used: \placefloat[Partfigure][here][-:PMRWFII]{A cow}{\externalfigure[koe]} Why not? \stoptext ---- I tried also \increment[Partfigure] but this produces exactly the same output. I also tried using ownnumber=true in the Partfigure setup and then feeding it the value {2} in the \placefloat call but that wouldn't compile. Where did I go wrong? I'm sure there is an easy way to do this. This one is a bit desperate, again, a very fussy author is waiting on it, so... Thanks all. Duncan

draw & fill
by Peter Rolf 19 Oct '06

Hi all, [maybe this is a bit off topic and you think that the Metapost mailing list is the right place for such stuff. But I have quit this list quite some time ago, as there was more spam than regular posts. Try to forgive me... :D ] After buying the 'Metafont' manual, I'm now playing around with some mp macro programming. The problem in the attached example is, that the 'draw' variants of the [hv]line macro always work with a *fixed* pen size of 1pt (and I can't figure out why). I'm clueless.. Greetings, Peter \setupoutput[pdftex] \setupcolors[state=start] \starttext \startMPinclusions % default unit u:= .5 ; % u:=1 works, u:=2 doesn't pen upen ; upen = makepen(unitsquare scaled u shifted -(.5u,.5u)) ; % width, height, shift-x, shift-y, color def fill_square(expr w,h,a,b,c)= fill unitsquare xyscaled(w*u,h*u) shifted (a*u,b*u) withcolor c enddef ; def fill_hline(expr w,a,b,c)= fill_square(w,u,a,b,c) enddef ; def fill_vline(expr h,a,b,c)= fill_square(u,h,a,b,c) enddef ; % the drawing macros always use a pen of 1pt ; % even with an extra defined pen def draw_hline(expr w,a,b,c)= draw (.5u,.5u)--(w*u-.5u,.5u) withpen upen shifted (a*u,b*u) withcolor c enddef ; def draw_vline(expr h,a,b,c)= draw (.5u,.5u)--(.5u,h*u-.5u) withpen pensquare scaled u shifted (a*u,b*u) withcolor c enddef ; def draw_frame(expr w,h,a,b,c)= draw (.5u,.5u)--(w*u-.5u,.5u)--(w*u-.5u,h*u-.5u)--(.5u,h*u-.5u)--cycle withpen pensquare scaled u shifted (a*u,b*u) withcolor c enddef ; \stopMPinclusions \startMPpage fill_hline(20,5,5,red) ; fill_vline(20,5,5,red) ; draw_vline(20,5,25,blue) ; draw_hline(20,25,5,blue) ; draw_frame(50,50,0,0,black) ; \stopMPpage \stoptext

multipage tables
by Gerhard Kugler 19 Oct '06

19 Oct '06

Hi, I must set two-page tables. The top row contains headings for the columns 2 to 4. The left column contains the hours of the day (01:00, 02:00 ... 24:00). The overall width is textwidth. Which sort of tables is siutable for this purpose? So far my endeavours deliver many errors. Gerhard -- Gerhard Kugler Psychotherapeut Bensheim (Germany) http://www.psychotherapie-kugler.de

Bug in ctxtools --purge
by Aditya Mahajan 18 Oct '06

18 Oct '06

Hi Hans, ctxtools --purge file.tex does not behave the same as ctxtools --purge file (no extension). This causes texexec --purge filename to misbehave. With ctxtools --purge test-04.tex I get f:\tmp\context\test>ctxtools --purge test-04.tex CtxTools | purging temporary files : test-04.tex CtxTools | checking files that match 'test-04.tex-*.*' CtxTools | checking files that match 'test-04.tex.*' CtxTools | removed files : 0 CtxTools | kept files : 0 CtxTools | persistent files : 0 CtxTools | reclaimed bytes : 0 which does not delete the temp files. However with ctxtools --purge test-04 the temp files are deleted. f:\tmp\context\test>ctxtools --purge test-04 CtxTools | purging temporary files : test-04 CtxTools | checking files that match 'test-04-*.*' CtxTools | checking files that match 'test-04.*' CtxTools | removed : test-04-mpgraph.mp CtxTools | removed : test-04.tui CtxTools | removed : test-04.log CtxTools | removed : test-04.tmp CtxTools | not removed : test-04.tuo CtxTools | removed files : 4 CtxTools | kept files : 1 CtxTools | persistent files : 0 CtxTools | reclaimed bytes : 23960 Shouldn't both the commands be equivalent. As a consequence of this, texexec --purge does not delete temp files. I get CtxTools | purging temporary files : test-04.tex CtxTools | checking files that match 'test-04.tex-*.*' CtxTools | checking files that match 'test-04.tex.*' CtxTools | removed : mpgraph.mp CtxTools | removed files : 1 CtxTools | kept files : 0 CtxTools | persistent files : 0 CtxTools | reclaimed bytes : 6 Only mpgraph.mp is removed.

U3D and presentation
by Renaud AUBIN 18 Oct '06

18 Oct '06

Hi all, I have tried to embed an U3D model within a presentation of mine and pre-original interactions inhibit the U3D interaction... The problem is described by http://www.nibua-r.org/ConTeXt/devel/context3d.tgz How to inhibit locally the interaction setted by pre-original ? I have tried to enclose my u3d model in a \framed and the result is that the 3D annotation is now activated but I can't interact with it since a click leads to get the next page... TIA Renaud
