placefigure & headers topframe interactions
by Renaud AUBIN 28 Jan '06

28 Jan '06

Hi all, I use in my document: \setupbackgrounds[header][text][bottomframe=on] \setupbackgrounds[footer][text][topframe=on] in order to obtain black rules. Since I don't want the topframe on in the chapter's first pages, I use in setuphead the option header=high... It works if I have only text in my document, but when I use \placefigure[here][fig:afigref]{A dummy label}{\externalfigure[dummy]} to include METAFUN or pdf graphics, I obtain a black rule (topframe) on top of the first page of the next chapter... Seems very strange... I tried to solve the problem but, unfortunately, without success ! Any idea ?

\hbox and figures
by andrea valle 28 Jan '06

28 Jan '06

Hi to all, I guess it's something obvious but... I was taking a look at the nice cows on p.298 cont-eni: I cannot understand why in compiling this code "test" is always one line down and never on the same line, just on quarter's side. Quarter is a small figure, and I tested with other small figures, both in pdf and png. \starttext \hbox {\externalfigure[quarter]} test \stoptext Many thanks! -a- Andrea Valle DAMS - Facoltà di Scienze della Formazione Università degli Studi di Torino http://www.semiotiche.it/andrea andrea.valle(a)unito.it

Chapters, setupbackgrounds[header] issue & indenting issue
by Renaud AUBIN 28 Jan '06

28 Jan '06

Hi all, I have made a small document in order to show you issues I have to face with. 1. At page 3, why do I have bottomframe=on in the header althought I use high option ? It's ok at page 1 and 4. 2. At page 4, it works only because the previous chapter is on one page ! Don't see why with my present ConTeXt skills. 3. Concerning indenting, the first paragraph of each section isn't indented, why and how to modify ? I have seen that the order of options matters but I don't understand how work "next" and "first" options because when I use it, I don't obtain indentation at all. What I'm doing wrong ??? It drives me crazy since these features are prerequisites for my PhD style ! Renaud

how to embed a postscript Times
by Steffen Wolfrum 27 Jan '06

27 Jan '06

Hi, I have to typeset a document in postscript Times Roman. I guess I have to use \usetypescript[postscript][\defaultencoding] \setupbodyfont[postscript,10pt] But is this enough to make sure that my Times is really embedded and not "overwritten" by the standard printer Times when the PDF is printed? (I don't feel comfortable when using these standard fonts, that everybody has but none are the same ...) Steffen

Typesetting chemical reaction equations
by Ville Voipio 27 Jan '06

27 Jan '06

I would need to typeset some rather simple reaction equations. I do not need the structural capabilities of PPCHTeX, just something simpler. The thing I am writing has something to do with physical chemistry, so I need mathematical equations, as well. Of course, the natural way to do this: \placeformula \startformula \rm NH_3(g) + H^+(aq.) + Cl^-(aq.) \rightarrow NH_4^+(aq.) + Cl^-(aq.) \stopformula This gives rather pleasant-looking results. However, is this the right (i.e. kosher) way of doing things, or do I run into trouble at some later point with this? What are you chemists using? And how do I switch off the equation numbering for the chemical reactions (I'd like to have the mathematical formulae still numbered)? TIA, - Ville

LaTeX array equivalence with multiline \lbrace
by Renaud AUBIN 27 Jan '06

27 Jan '06

Hi all, With LaTeX, I have $$ \left\lbrace \begin{array}{l} \dot{q}_i = 1 \quad\text{ if } i=k \\ \dot{q}_i = 0 \quad\text{ else} \end{array} \right $$ How to do this within a ConTeXt document ?

itemize[loose]
by Hans van der Meer 27 Jan '06

27 Jan '06

When typesetting an enumeration with a specified item text I encountered an error with the combination of [loose] with \sym{} and \mar{}. The hope was that "loose" will allow underfull filling of the lines without complaint (I don't like TeX complaining) An example follows: \starttext \setupitemize[loose] \startitemize \sym {xyz} 12345 \stopitemize \stoptext Error message: ! Undefined control sequence. <argument> \optimizeitemsfalse \p!compareprocessaction ...commalistelement {#3}#2 \expandafter \quitcommalis... etc. Is this expected behaviour? The manual does not give me an idea about that. yours sincerely, dr. H. van der Meer

SVG images
by Ville Voipio 26 Jan '06

26 Jan '06

I would need to embed some SVG images into a ConTeXt document. I have done some research on the topic, and the seemingly trivial task seems all but impossible. I found a few solutions, but none of them fits my needs: - I want to have my vector images in vector format (i.e., no Inkscape-to-PNG) - alpha-channel transparency is used in the images, and it should be present in the PDF file, as well (i.e., no Inkscape-to-EPS) - if I used commercial products, I would not use SVG (i.e., the converter should be open source) The images have been (will be) created with Inkscape. While being otherwise a surprisingly nice piece of software, Inkscape does not seem to export PDF for some reason or another (licencing, time, etc.). I have the impression I just ran out of luck. Did I? - Ville

color in before=
by Hans van der Meer 26 Jan '06

26 Jan '06

I want to put a color command in a "before" command, that command being inserted in a macro. Something like \setupxyz[before=\color[green]{whatever}] The problem is that the argument parser gets confused when []- expressions are found within the setup. It is not an option to reprogram everything with {}'s instead of []'s, because then I lose to much of ConTeXt's abilities (apart from the nuisance of having to reprogram something that has already been done). I suspect there is no way of sneaking in these []'s inside the command? That is the general solution. My eyes spotted something like \dowithcolor#1#2, but there TeX complains about not knowing \od. Is there a solution to this problem? yours sincerely, dr. H. van der Meer
