PI Number.
by Janez Luzar 25 Jan '12

25 Jan '12

Dear all, Few months ago a PI letter surrounded with developed pi numbers in spherical case has been noticed in one Context publication. I would be very pleased if anyone knows in which document it is or how can I design set of numbers or text in spherical shape. Thank You very much in advance. Janez

math error in ConTeXt?
by Meer, H. van der 25 Jan '12

25 Jan '12

Of these two variants the second works. The first gives as error an old enemy: the \Umathquad error % gives an error: \startsetups[test] $\displaystyle a=1 $ \stopsetups \setup[test] \stoptext % works: \starttext $$\displaylines{a=1\cr b+c+d=3\cr}$$ \stoptext ConTeXt ver: 2012.01.16 18:33 MKIV ! Math error: parameter \Umathquad\displaystyle is not set. \8>:test #1->$\displaystyle a=1$ Why this error? Hans van der Meer

\externalfigure and file size
by Kip Warner 24 Jan '12

24 Jan '12

Hey list, I have a number of \externalfigure commands to typeset some svg images. This is often handy to have them vectorized because it allows for the user to zoom in on diagrams of great detail. In other situations, I find that for images that are not so important, they would benefit from ConTeXt rasterizing them when they are imported. The reason for this is I find some vector images get enormously bloated when they are typeset. As an example, I have a Logo.svg of only 6.8 KB. The m_k_i_v_Logo.pdf intermediate ConTeXt generates is nearly a megabyte in size. Why? I have no idea, as they both appear to be the same image with the same gausian blur. Is there a flag I can pass certain instances of \externalfigure that tells the image processing backend that a simple rasterized version of the figure is fine? Or is there a better approach? I don't want to pre-convert all of these images to raster formats. -- Kip Warner -- Software Engineer OpenPGP encrypted/signed mail preferred http://www.thevertigo.com

beta
by Hans Hagen 24 Jan '12

24 Jan '12

Hi, I uploaded a beta to the website. The most important upgrades concern the font subsystem. - there was still some mkii code around ... all that has gone ... as a consequence all code has been overhauled (a rather tedious job) ... some code might be a bit faster (but nothing fundamental changed) - designsizes are now dealt with in a different way but as only lm has them no one will probably notice .. anyway it saves a lot of definitions and (at least on my machine) the start up is somewhat faster - the type-otf file is no longer used but its content has been distributed over a some smaller files ... loading these files is rather automatic and it should be compatible .. again this might give a (small) startup speed improvement (and a bit less memory which quite certainly goes unnoticed compared to the average memory usage) - bodyfont environments are a bit more flexible now which was one of the reasons for rewriting much code as there is some complex inheritance and defaulting going on there - Wolfgang is adapting / extending the simple fonts code but in principle it should still work In addition, the lists related code has been reorganized / redone and it seems to be ok. There have been some conceptual changes to the list rendering (easier for future extensions) but old commands still apply. It's anyhow still somewhat experimental. Of course there are some fixes and other cleanups done.

\note does not preserve formatting -- example
by Peter Park Nelson 24 Jan '12

24 Jan '12

After updating to the current beta, I discovered that the \note macro does not format the note marker correctly. In the minimal example below, I define an item group for a paragraph-formatted list of article authors, and an "affiliation" note for a paragraph-formatted list of affiliations below them. (This is fairly common in academic journals; I have left out most of the text formatting.) The note marks for the third and fourth authors (Jones and Mandrell), which are created using the \note macro to reference previous affiliations, are too small and not bold. I would guess this is related to changes around line 122 of strc-not.mkiv, dealing with the handling of note attributes (see: \def\usenotestyleandcolor). \setuppapersize[letter][letter] \defineitemgroup[Authorlist] \setupitemgroup[Authorlist] [each] [text] [symbol=0, margin=no, align=normal, width=-10pt, distance=0pt, leftmargin=no, location=top, textdistance=big] \definenote[affiliation] [numbercommand=\ss, textstyle=\tfx\bf, paragraph=yes] \setupnotedefinition[affiliation] [location=serried, distance=.4em, display=no] \starttext \startlocalnotes[affiliation] \startAuthorlist % Convenience macros for setting up some affiliations separately: \def\useaffiliation#1{\note[#1]} \def\makeaffiliation[#1]#2{\setnotetext[affiliation][#1]{#2}} \makeaffiliation[opry]{The Grand Ole Opry} % The list of authors: \item Doris Doe\affiliation[misk]{Miskatonic University} \item Robert Roe\affiliation[love]{Lovecraft Institute} \item Cleopatra~Jones\note[misk] \item Barbara Mandrell\useaffiliation{opry} \stopAuthorlist \placelocalnotes[affiliation] \stoplocalnotes \stoptext -- Peter Park Nelson peter.park.nelson(a)gmail.com

Footnote marker inside custom list environment - font problem
by Peter Park Nelson 23 Jan '12

23 Jan '12

Hello, Maybe this is related to the problems with \definenote posted recently...I have played with setups but have been unable to figure this one out. I have a custom enumeration environment to display the names of journal authors in a paragraph format, with local footnotes for their affiliations. Since updating, it no longer works as expected; the footnote markers after author names use the document roman font instead of the sans font. Also, if I use this inside a \startnarrower...\stopnarrower block, the environment extends past where it should stop, which didn't happen before. \defineitemgroup[Authorlist] \setupitemgroup[Authorlist] [each] [text] [symbol=0, margin=no, align=normal, width=-10pt, distance=0pt, leftmargin=no, location=top, textdistance=big] \definenote[affiliation] [numberconversion=Characters, style=\tfa\ss\bf, numbercommand=, paragraph=yes] \setupnotedefinition[affiliation] [location=serried, distance=.2em, display=no, style=\tfa\ss] \starttext \startAuthorlist \item Doris Doe\affiliation[misk]{Miskatonic University, Dept. of Allopatric Studies} \stopAuthorlist \stopAuthorlist \stoptext -- Peter Park Nelson peter.park.nelson(a)gmail.com
