beta: bug with transparent colors in fields
by Peter Rolf 14 Nov '06

14 Nov '06

Hi Hans, the support of transparent colors in fields seems to be broken (beta 03.11.06). The attached example works with a non transparent backgroundcolor, but breaks with a transparent one. Same behaviour on ConTeXt Live. \definecolor [notebackgroundcolor] % [s=.85] [s=1,a=1,t=.9] There is another problem with field activation (not in this example). When the doc opens, the fields (region in/out) are kind of inactive. Normally a tooltip note is shown/hidden, if the area is entered/left. Only after "activating" the fields by pressing "R" and "H" in Acrobat, they become alive. After that they work as expected. I am still working on a minimal example for this case. Greetings, Peter \setupoutput[pdf] \setuppapersize[S6][S6] \startJSpreamble {Notes} used now var lastNote = "" ; function Show_Note ( Name ) { if (Name != lastNote) { Hide_Note () ; var v = this.getField(Name) ; if (v) { console.println("Show Note: " + Name) ; v.display = display.visible ; v.readonly = false ; % v.richText = true ; % v.multiline = true ; % v.lineWidth = 3 ; % v.rect = [0, 0, 200, 150] ; this.dirty = false ; lastNote = Name } } else {Hide_Note () ;} } function Hide_Note ( ) { if (lastNote != "") { var v = this.getField(lastNote) ; if (v) { console.println("Hide Note: " + lastNote) ; v.display = display.hidden ; v.readonly = true ; this.dirty = false } } lastNote = "" } function Set_Tooltip ( Name ) { if (Name != "") { var v= this.getField(Name) ; if (v) { v.userName="This may help..." ; } } } \stopJSpreamble \newcounter\AnotherNote \def\SomeNote#1#2% {\hbox {\doglobal\increment\AnotherNote \definesymbol[note:\AnotherNote:on][\WhatANote{#2}]% % \setupfield[notes][offset=overlay,frame=off,option={readonly,hidden}] % this confuses acrobat, probably some interference bug, I spent too much time on that \setupfield[notes][offset=overlay,frame=off,option={readonly,hidden},% % regionin=JS(Hide_Note), regionout=JS(Hide_Note), username={Test!}, % clickin=JS(Hide_Note), % clickout=JS(Hide_Note), ] \definefield[note:\AnotherNote][check][notes][note:\AnotherNote:on,note:\AnotherNote:on][note:\AnotherNote:on]% \doifreferencefoundelse{note:\AnotherNote} {\setlayer[notes][page=\currentrealreference]{\fitfield[note:\AnotherNote]}} {\setlayer[notes]{\fitfield[note:\AnotherNote]}}% \pagereference[note:\AnotherNote]\goto{#1}[JS(Show_Note{note:\AnotherNote})]}} \setupinteraction [state=start, openpageaction=JS(Hide_Note), closepageaction=JS(Hide_Note)] \definereference[CloseNote][JS(Hide_Note)] \setupfootertexts[{\goto{Close Note}[CloseNote]}][] \setupcolors [state=start] \definecolor [notebackgroundcolor] % [s=.85] [s=1,a=1,t=.9] \defineframedtext [WhatANote] [bodyfont=9pt, background=color, backgroundcolor=notebackgroundcolor, width=.4\textwidth, height=fit, align=normal] \definelayer [notes] [width=\paperwidth, height=\paperheight, preset=rightbottom, offset=1cm] \setupbackgrounds [page] [background={notes,foreground}] \starttext \startbuffer \input ward \SomeNote{[[ward]]} {\input ward \relax} \input ward \blank \input knuth \SomeNote{[[knuth]]} {\input knuth \relax} \input knuth \blank \input tufte \SomeNote{[[tufte]]} {\input tufte \relax} \input tufte \blank \input bryson \SomeNote{[[bryson]]}{\input bryson\relax} \input bryson \blank \stopbuffer \dorecurse{10}{\getbuffer} \stoptext

Avoiding page breaks in self-defined Note environment
by Martin Becker 14 Nov '06

14 Nov '06

Dear all, I'm having a problem with unwanted page breaks using ConTeXt. Imagine a note environment that is separated from normal text by horizontal rules: -------------------------- Note - Notice that this text is embedded in... -------------------------- The problem however is that ConTeXt sometimes breaks the page after the first rule or just before the second, which, as you can image, is pretty ugly. I have defined a command to avoid this: \def\MyHR{nobreak\hairline\nobreak } The tex file looks like this: \MyHR{} {\bf{Note --}} Notice that this text is embedded in... \MyHR{} However, this does not work. The background is that I am using a parser to translate MediaWiki markup to PDF using ConTeXt. Any help would be appreciated. Thanks in advance. Martin Becker

combining multiple accents
by Mojca Miklavec 14 Nov '06

14 Nov '06

Hello, I always thought that "any accent can be placed on any character" in TeX. However, probably due to some boxes, this fails to work sometimes. So how can I create "a with cedilla and ring above" for example: \r{\c a}? (Yes, I know that I can switch the order: \c{\r a} works as expected, but I need to create more complicated cases in general and I don't want to depend on whether the accent will be placed properly or not.) Is there any simple cure for that? Thanks a lot, Mojca

typesetting proofs
by Dalyoung Jeong 14 Nov '06

14 Nov '06

Dear all, Searching the lists, I found one and I got the output what I want as following image. But, as you noticed, there is a lot spaces between "Theorem" and the start of the text. Also there is the same space between "Proof" and the start of the text. Is it normal? or Is there any method to reduce the spaces? Thank you for reading. Dalyoung %Here is the definition following Mr. Taco's method \defineenumeration[Theorem] [location=serried, headstyle=bold, text=Theorem, number=yes, after=] \definestartstop[theorem] [before=\startTheorem, after=\stopTheorem] \defineenumeration[Proof] [location=serried, headstyle=slanted, text=Proof, number=no, after=] \definestartstop[proof] [before=\startProof, after=\hfil \stopProof] ...... \startTheorem $P(n, r) = C(n,r).... \stopTheorem \startProof An ordered arrangement... \stopProof ......... %output

Shapes spanning multiple grid cells in flowchart
by Martijn Martijn 14 Nov '06

14 Nov '06

Hello, I've just started to use Context because of its great flowcharting module. However, I'd like to use shapes that span multiple grid cells. This is what I would like to accomplish: |-------| |-------| |-------| | |<-->| box 2 |<-->| box 3 | | | |-------| |-------| | box 1 | | | |-------| |-------| | |<-->| box 4 |<-->| box 5 | | | |-------| |-------| | | | | | | |-------| I could not find a way to do this in the manual. Every shape in the manual has the same size. Thanks for the help! Martijn

Chemical structure formula flows out
by Zhichu Chen 14 Nov '06

14 Nov '06

Hello I've been studying PPCHTEX these days, it's very powerful, and I cannot control it well. I just wrote a chemical struture like: ================================ \startchemical [size=small,scale=small,width=fit,height=fit,frame=on] \chemical[SIX,SB13456,DB2,Z] [C,C,C,C,C,C] \chemical[PB:Z1,ONE,Z0,SB18,Z8,MOV1,ONE,DB1,SB7,Z07,MOV1,ONE,SB13,Z03,MOV1,ONE,SB1,DB7,Z017,PE] [C,H,C,H,C,H,C,CH_3,O] \chemical[PB:Z2,ONE,Z0,SB1,Z1,PE] [C,CH_3] \chemical[PB:Z3,ONE,Z0,SB3,Z3,PE] [C,H] \chemical[PB:Z4,ONE,Z0,SB45,Z45,PE] [C,H,H] \chemical[PB:Z5,ONE,Z0,SB56,Z56,PE] [C,CH_3,H] \chemical[PB:Z6,SIX,Z3,SB23,Z24,PE] [C,CH_3,CH_3] \stopchemical ================================ only the carbon-ring is in the frame, I think maybe PB:..,PE pair does not change the size of the picture. I know I can use like ================================ \startchemical [size=small,scale=small,width=9000,height=5000,left=3000] ================================ to specify the size, but I need to try several times to get a correct version. Is there any parameter that do this staff automatically?

Meeting NTG saturday 18 november 2006
by Willi Egger 13 Nov '06

13 Nov '06

Dear list user, The Dutch TeX users group organizes a meeting on saturday 18 november. Location: Highschool Helicon, Zeist, The Netherlands. Theme: "The next generation TeX - a glance on the future" At the this moment active development takes place for the successor of pdfTeX. During next year this engine will be dirstributed. Next to this, steps are undertaken to improve the integration of the graphical possibilities of Metapost.in TeX. A bunch of new fonts are in the pipeline which can replace existing (free) font-collections: extended, improved, OTF versions. There are different initiatives for enhancing TeX and related programs e.g. giving them a more modern, up-to-date interface. Further one can see, that TeX is moving form the front-end into the background, so that users do not even know that the final work is performed with TeX. The mentioned aspects will be discussed and presented during the upcoming NTG-meeting. The NTG would like to invite you to join us. Global programme: 09 :30 arrival 10:00 opening, presentations/discussion 11:15 coffee break 11:45 presentations/discussion 12:45-13.30 lunch 13:30 presentations/discussion 15:00 Thea break 15:30 presentations/discussion 16:30 closing 17:30 Diner in one of the restaurants in Zeist Issues to be presented: luatex: development of the next generation pdfTeX opentype: the first three delivered replacement fonts from the polish "foundry" metapost: on its way to full integration into TeX epspdfgui: Good-bye to obscure commandline programs processing in the background ...: how Tex moves behind the scene pgf: replacement of macros containing graphics TeXlive: the in's en out's of preparing a distribution Description of the location and how to get there: http://www.hhelicon.nl/index2.html If you would like to join in, please send an e-mail to the NTG secretary: ntg-secretaris(a)ntg.nl Kind regards Willi Egger Secretary NTG

underbar in MP text
by Peter Rolf 13 Nov '06

13 Nov '06

Hi all, if \underbar is used inside a MP text, it always uses a fixed rule thickness, regardless of the settings in ConTeXt. How can I change this? TIA, Peter \setupoutput[pdftex] \setMPtext{testtext} {} \startusableMPgraphic{mptext} draw textext.rt(\MPstring{testtext}) ; \stopusableMPgraphic \starttext \setupunderbar[rulethickness=2pt] \underbar{Thick line} \setMPtext{testtext}{\underbar{Thick line}} \useMPgraphic{mptext} \setupunderbar[rulethickness=.15pt] \underbar{Thin line} \setMPtext{testtext}{\underbar{Thin line}} \useMPgraphic{mptext} \stoptext
