Font size in FLOWchart module.
by John R. Culleton 02 Jun '06

02 Jun '06

I am using the flowchart module to create various goodies. What I don't know how to do is regulate the size of the font for the text that goes inside the little boxes. Any suggestions? - John Culleton Books with answers to marketing and publishing questions: http://wexfordpress.com/tex/shortlist.pdf Book coaches, consultants and packagers: http://wexfordpress.com/tex/packagers.pdf

\to broken in figure captions

slithering captions
by Sanjoy Mahajan 22 May '06

22 May '06

One weekend years ago I studied tex's insertions and learnt enough to write (i.e. hack) macros to produce a layout that I'm trying to reproduce using ConTeXt. I've figured parts of it out, no doubt the easier parts. The layout has a 4in text column and a 2.3in right margin for figures and captions. Experiments with setuplayout got those blocks working. But figures are to be placed according to their width. Three natural widths appear in the layout: 1. margin (2.3in) 2. text (4in) 3. text + margin (+ gutter) = 6.5in You can see the results of the plain-TeX implementation in the book chapters at <http://www.inference.phy.cam.ac.uk/sanjoy/mit/>. A figure is then placed in one of three ways: 1. width <= margin: margin float, with caption below it. One example is p.8 of chapter 1. 2. width <= text: float to top of page, with caption in the right margin. One example is p.7 of chapter 1. 3. width <= text + margin + gutter: float to top of page, bleeding into the margin, with caption below it in the margin. One example is p. 11 of chapter 1. So the first step in doing the placement automatically is to get the width of the figure. Assuming that I've done \useexternalfigure[fig_a][f-1.pdf] is there an easy way to get fig_a's dimensions? After using the figure, e.g. with \placefigure[margin][]{some caption}{\externalfigure[fig_a]} then \wd\floatbox has the dimension I need. Will another macro fill in \floatbox without doing the work of using the figure? I tried \dogetfiguresizetex but probably with wrong arguments. Another option was \newdimen\a \newdimen\b \newdimen\c \newdimen\d \dogetPDFmediabox{f-1.pdf}{\a}{\b}{\c}{\d} and then \c has the width, but without any scaling and only for pdf figures. Once I have the width, I can define \autofig and use it like so: \autofig{L}{caption} and \autofig will look up the width of the figure labeled L and do roughly: \placefigure[margin][]{caption}{\externalfigure[L]} % margin figures OR {\setupcaptions[location=middle] % for text figures \placefigure[top][]{caption}{\externalfigure[L]} } OR {\setupcaptions[width=2.3in,align=right] % for even wider figures \placefigure[top][]{caption}{\externalfigure[L]} } The next problem after finding the figure width is to find the right alternative to location=middle (which puts the caption to the left, whereas I wanted it in the margin and to the right). And, but this is trying to do too much at once, the next problem is that margin caption below the widest figures (case 3 above) shouldn't overlap other floats in the margin and also shouldn't count toward the figure's height in the text block. But maybe that's done automatically -- I'll make some experiments. Any hints greatly appreciated, and, once I get it working, I'll wikify the layout if there's interest. -Sanjoy `A society of sheep must in time beget a government of wolves.' - Bertrand de Jouvenal

spurious space before section heading but only in pdf mode
by Sanjoy Mahajan 17 May '06

17 May '06

This file \starttext \section{a} hi \section{b} hi again \stoptext is fine in dvi mode (texexec a.tex). But 'texexec --pdf a.tex' is a bit off, with the "1 a" section heading indented about one character. Is it a pdfetex bug? $ texexec --version TeXExec 5.4.3 - ConTeXt / PRAGMA ADE 1997-2005 texexec : TeXExec 5.4.3 - ConTeXt / PRAGMA ADE 1997-2005 texutil : TeXUtil 9.0.1 - ConTeXt / PRAGMA ADE 1992-2006 tex : pdfeTeX, 3.141592-1.21a-2.2 (Web2C 7.5.4) context : ver: 2006.03.25 13:21 cont-en : ver: 2006.03.25 13:21 fmt: 2006.4.8 mes: english The only change from the distributed context version is Taco's suggestion of \def\maxreadlevel{4} in supp-fil.tex. -Sanjoy `A society of sheep must in time beget a government of wolves.' - Bertrand de Jouvenal

defineenumeration and setupenumeration
by WN 05 May '06

05 May '06

Hi, I have a question (probably a dumb question) relating to some of the define/setup commands. One in particular, but it may relate to the other define/setup commands as well. Looking at the defineenumeration and setupenumerations command in the Context manual page 223 and page 224 an example is given how to use these commands. I am a bit confused, the example setups the enumaration *remark* and specifies the location=top \defineenumeration [remark] *[location=top,* text=Remark, between=\blank, before=\blank, after=\blank] But on page 224 the command \setupenumerations is shown where one can also specify the location among others. What is the difference, reason or usage for doing this ? What is the proper Context way, should I define the location with \defineenumeration or with \setupenumerations ? Kind regards Wim

Part head centering and empty header
by Johannes Graumann 04 May '06

04 May '06

Hello I have coded my 'Appendix' like so: \setuphead [part] [ header=empty, footer=empty, alternative=middle, placehead=yes, resetnumber=no, number=no, style={ \ss\switchtobodyfont[60pt]\setupinterlinespace[line=2.8ex] }, page=right ] \startappendices \setuppagenumbering[way=bytext,partnumber=no,conversion=numbers,location={header,right}] \framed [% height=\textheight,% frame=off,% ] { \part{Appendices} } {\stopappendices} Which gives me a nicely vertically and horizontally centered title. One problem remains though: I can't get rid of the page number. The framed '\setuphead[part]' commands concerning header and footer are being overruled and I can't figure out how to have an empty header for just the page containing the frame. Thanks for any hints, Joh

some basic TABLE questions
by Karsten Heymann 03 May '06

03 May '06

Hello, it would be very kind if someone could answer the following questions about the possibilities of TABLE: - there some semi-automatic way of splitting tables on multiple pages if those tables are in landscape mode (which I achieve by putting them into a \rotating{}-Command)? - How do I add a caption to (portrait) multipage TABLEs? \placefigure obviously doesn't work. Any help would be very much appreciated!

Table of contents and List of figures
by WN 01 May '06

Question 1) : In my document I am using \setupcombinedlist[content][alternative=c,aligntitle=no,width=4em] and now I want to use the same layout for the list of figures but there is not something equivalent like \setupcombinedlist[figure][alternative=c,aligntitle=no,width=4em] Question 2): In my document I am also using \part and in the TOC the part number prefixes the pagenumber like Deel I Klassieke Elektrodynamica . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1–1 1 De Maxwell vergelĳkingen in vacuüm . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1–3 1.1 Inleiding . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1–10 1.2 Behoud van lading . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1–20 1.3 Energie en impuls van het elektromagnetische veld . . . . . . . . . . . . . . . . . . . 1–35 I want to get rid of the partnumbers which are prefixed to the pagenumbers so my TOC looks like Deel I Klassieke Elektrodynamica . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 1 De Maxwell vergelĳkingen in vacuüm . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 1.1 Inleiding . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 1.2 Behoud van lading . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20 1.3 Energie en impuls van het elektromagnetische veld . . . . . . . . . . . . . . . . . . . 35 How can one achieve this in Context ?
