MetaPost bug? in MKIV
by Troy Henderson 08 Mar '10

08 Mar '10

The following example produces expected output with MKII (texexec) but fails the compilation process with MKIV (context). \startuseMPgraphic{foo} input graph; path p; gdata("data.d", $, augment.p($1,$2);); draw begingraph(4in,2.5in); gdraw p; endgraph; \stopuseMPgraphic \starttext \useMPgraphic{foo} \stoptext The data stored in data.d is as follows: 0 0 1 1 2 4 When compiling with MKIV, the following error occurs: !mplib : mp terminal: (/opt/context-minimals/tex/texmf/metapost/base/graph.mp ! Redundant equation. <to be read again> ; l.143 Gmargin.low=-.07; % bbox fraction for default ra... ! Redundant equation. <to be read again> ; l.144 Gmargin.high=1.07; % bbox fraction for default ra... ) !mplib : mp error: unknown, no error, terminal or log messages !mplib : mp terminal: [1] !mplib : mp error: unknown, no error, terminal or log messages -- Troy Henderson

Where to put a module?
by Philipp Gesang 08 Mar '10

08 Mar '10

Dear listmates, a while ago I made some lua tables to aid myself in transliteration of various scripts. I thought this could be of general interest so I built a module from it and threw in some source documentation and a tiny manual, too. Right now it contains modes for Cyrillic, Glagolitic and Greek scripts, older variants included, full ISO 9 support, and two transcription modes as well. (There's a showcase of examples in the manual.) It allows global setups and local adjustments. It splendidly works for me, but maybe somebody wants to review it before I post it on the list, so whom should I send it to?

Where is the cow?
by Matthias Weber 07 Mar '10

07 Mar '10

Dear all, maybe a catchy subject line will get attention -:) Indeed, the cow seems to be missing in mk2 and is overly present in mk4 in the sense that my own image cow.jpg within the same directory as the document below gets ignored in favor of the cow that's present in the mk4 minimals. These are minor issues, as it is relatively unlikely that I will need to include images of cows in my documents in the near future. What is bothering me however is my inability to combine figures properly together with text in a controlled manner. I have a bunch ow smallish images (let's call them cows) which I'd like to have surrounded by text. I am happy and actually prefer to do this manually instead of keeping my fingers crossed that some automatic algorithm will do the job, but for that I need to know how which version of ConTeXt is placing the figures. What would work for me: A way to split the text width into chunks that have fixed widths, and fill these chunks individually and vertically with figures or text. This might be possible with tables, but there should be a simpler way. Below are my attempts so far - with very frustrating results, both in mk2 and mk4. Matthias \setupbodyfont[12pt] \setupcolors[state=start] \setuplayout[grid=yes] \showgrid \setupcolor[rgb] \definecolor[defc] [r=.9,g=.9,b=.94] \definetextbackground [defbackground] [backgroundcolor=defc, corner=round, before=\blank, after=\blank, leftoffset=5pt, rightoffset=5pt, topoffset=5pt, bottomoffset=5pt, frame=on, framecolor=darkblue, location=paragraph, color=darkred] \defineenumeration [blurb] [before={\starttextbackground[defbackground]}, after={\stoptextbackground}, text=Blurb, way=bysection, location=hanging, letter=rm] \setupframedtexts[background=color,backgroundcolor=defc, corner=round, before=\blank, after=\blank, leftoffset=5pt, rightoffset=5pt, topoffset=5pt, bottomoffset=5pt, frame=on, framecolor=darkblue, location=paragraph, color=darkred] \starttext \startblurb Why is the topoffset so small?

The figure is too low. \stopblurb \startfiguretext [left]{none}{\externalfigure[cow][width=2in]} \startblurb Something is very wrong here. \stopblurb \stopfiguretext \page \startframedtext Why is the offset so big? \stopframedtext \placefigure[left]{none}{\externalfigure[cow][width=3cm]} \startframedtext How do I combine this text with the figure? \stopframedtext For some reason, this text is placed correctly. \stoptext

bib module, inproceedings & mkii/mkiv incompatibility
by Mojca Miklavec 07 Mar '10

07 Mar '10

Hello Taco, the following example (I need to admit that I'm not sure how to properly cite inproceedings) returns a different result in mkii and mkiv. My citation (the fields I use) is probably a bit wrong, but the results should be the same in my opinion. (Only mkii shows the year, in mkiv there's an extra space; the month is not shown anywhere, pubname is only shown in mkii although it's probably not needed anyway since it's already the title (= booktitle in bibtex?) that takes that role. It's also not really clear to me why I need to use author and not artauthor, but well ...) It may be sensible to have some reference about which fields are sensible for what type of publication also among the ConTeXt manuals. >From some unofficial BibTeX reference (http://www.kfunigraz.ac.at/~binder/texhelp/bibtx-14.html) Format: @INPROCEEDINGS{citation_key, required_fields [, optional_fields] } Required fields: author, title, booktitle, year Optional fields: editor, pages, organization, publisher, address, month, note, key \usemodule [bib] \setuppublications [alternative=num, criterium=all, sorttype=cite] \startpublication [k=3Ddosimetry, t=inproceedings, a=Kormoll, s=, u=] \arttitle{3D In-vivo Dosimetry for Photon Radiotherapy Based on Pair Production} \title{IEEE Nuclear Science Symposium Medical Imaging Conference Record} \author[]{Thomas}[T.]{}{Kormoll} \author[]{Daniela}[D.]{}{Kunath} \author[]{Wolfgang}[W.]{}{Enghardt} \volume{} \issue{} \city{Orlando, Florida} \pubyear{2009} \pubname{IEEE Nuclear Science Symposium Conference Record} \month{October} \day{25-31} \pages{2969-2975} \doi{} \abstract{} \stoppublication \starttext \cite[3Ddosimetry] \placepublications \stoptext Thanks, Mojca

> \setupexternalfigures[location={local,global,default}] > local : currentdirectory + .. + ../.. > global : paths set with 'directory=...' > default : tex tree Hi Wolfgang, I want to draw your attention about what Texshow says \setupexternalfigures: global: the whole current project environment local: this 'directory' option default: the global texmf tree none: actual directory directory: local directory for figure files The differences I see are: 1) 'local' without 'directory' searches within current folder 2) it also searches in upper and 2 levels upper folders. Is it new behaviour for mkiv? Vyatcheslav

MetaPost filesize
by Troy Henderson 07 Mar '10

07 Mar '10

I am writing because there appears to be a very large (i.e., approximately a factor of 10) difference in filesizes of the same MetaPost graphic generated in the following 2 ways (1) Including a common MetaPost source "common.mp" into a minimal MKIV document and compiling with `context surface.tex` (2) Including the same "common.mp" into a minimal MetaPost source file and compiling with `mpost surface.mp` followed by a `epstopdf surface.mps`. In case (1), the resulting PDF is about 445kB whereas in case (2) the resulting PDF is about 45kB. I've attached the "surface.tex", "surface.mp", and "common.mp" for those that wish to test this and help determine why ConTeXt's output is so much larger than MetaPost+epstopdf. Thanks in advance for the help. Troy Henderson

I have exactly the same problem with the current ConTeXt Minimals. Nicola

Crop Output
by Troy Henderson 07 Mar '10

07 Mar '10

Is it possible to get ConTeXt (MKIV) to automatically crop out the whitespace from its PDF output? I know that I can use the external utility `pdfcrop`, but I was wondering if this is possible with ConTeXt itself. This would be useful when generating MetaPost graphics where the graphic is the only thing in the ConTeXt output. Thanks, Troy Henderson

Embedding fonts
by Tom 06 Mar '10

06 Mar '10

Printers that I deal with want the PDFs to have the fonts embedded. The PDFs that Texlive produces don't appear to have their fonts embedded and I can't find what option I must set or routine that must be run to embed the fonts. Tom Benjey 717-258-9733 voice 717-243-0074 fax Twitter: @TomBenjey

Table of contents disappears when \setuparranging is used
by berend＠pobox.com 06 Mar '10

06 Mar '10

Hi People, I have a very weird problem. As soon as I star tot use \setuparranging the table of contents and other registers disappear. How to fix that? An example file: -------------------------------------------------- \setuppapersize [A5][A4] \setuparranging [2SIDE,rotated] \starttext \subject{Table of contents} \placecontent[1] \chapter{Hello} World. \stoptext -------------------------------------------------- There will be no text under "table of contents". Comment out \setuparranging and then the table of contents appears. When \setuparranging is enabled, this appears in the log file: system : part,chapter,section,subsection,subsubsection,subsubsubsectio n,subsubsubsubsection not found/processed -- All the best, Berend de Boer
