visualization problem

Dear all, I've created this. http://www.cirma.unito.it/research/alternando/photoBook.pdf (it's 5 mB) The cover and the separators in the pages are generated stretching on layers the same image (a pdf generated by Metapost) % cover \setlayer [mybg] [x=0\paperwidth, y=0\paperheight] {\color[lightgray]\externalfigure[alternando] [height=1\paperheight,width=1\paperwidth]} % red horizontal separator \setlayer [mybg2] [x=0\paperwidth, y=.45\paperheight] {\color[darkred]\externalfigure[alternando] [height=.1\paperheight,width=\paperwidth]} % gray vertical separator \setlayer [mybg3] [x=.9\paperwidth, y=0\paperheight] {\color[lightgray]\externalfigure[alternando] [height=\paperheight,width=.05\paperwidth]} In Preview.app on macosx it's all displayed as expected (this is a png snapshot of the horizontal separator: http://www.cirma.unito.it/research/alternando/hbar.png ). But Acrobat displays the separators (the cover is ok) as a sequence of filled boxes. Can it depends on some resolutions setting? Or what? -a- -------------------------------------------------- Andrea Valle -------------------------------------------------- CIRMA - DAMS Università degli Studi di Torino --> http://www.cirma.unito.it/andrea/ --> andrea.valle(a)unito.it -------------------------------------------------- I did this interview where I just mentioned that I read Foucault.

Well, I can stand naked and do my little dance, or I can discuss Foucault, but not at the same time; too much information. (Annabel Chong)

Margins around figures
by Kumar Appaiah 08 Sep '07

08 Sep '07

Deat ConTeXt users, I am making a presentation with ConTeXt, with numerous MetaPost figures. Now, the only problem is that my white MetaPost figures don't blend well with the dark background of the screen. This isn't too good since the text labels in my figure's edges appear too close to the edge. What I'd like to know is, whether there's a way to specify some extra margin space around the figure, which would provide some more white area around the MetaPost figure. Alternately, is there an elegant MetaPost way of specifying figure margins? Oh, and my MetaPost files are in separate .mp files; I include them after converting. Thanks!

But I don't understand the whole thing. If I understand you right, the c!start is for increasing the itemizelevel NOT the numbering. So I wonder why the later is affected.

how to change 'figure 1.1' to '그림 1.1'
by Jeong Dalyoung 07 Sep '07

07 Sep '07

Hello, \placefloat will put 'figure 1.1' or 'table 1.1' below the figures(or tables). I'd like to change figure or table to my own language. I looked into the manual, but there is no option which change "figure or table". I tried "definefloat[그림][그림들]", but ConTeXt did not accept it. Is there a way to change them? Thank you. Best regards, Dalyoung

Hi, have you working installation of latest context and luatex on linux/amd64? Drop some info please. I have no problem with installation on 32bit machine. The same system (gentoo) on 64bit doesn't generate "cont-en.fmt". Lua and luatex are installed from source. Zdenek

mkiv and xml
by Hans Hagen 05 Sep '07

05 Sep '07

Hi, I uploaded a new beta which may be of interest to xml lovers. The current (mkii) XML handler is based on hooking code into active < characters. This works ok but has limitations. In MKIV we will have an alternative method which has a few advantages: = you have access to arbitrary elements using a subset of xpath = you can attach fully expandable hooks to elements, using 'setups' = for manu cases xml processing is faster (no need for definitions and save/flush) = with lua as programming environemnt rather tricky manipulations are possible The downside of this method is = loading a document eats a bit of memory Think of this: First we load a file (pretty fast btw given that the whole tree is built in memory in such a way that it can also be flushed as-is) \xmlload{main}{cont-en.xml}{} We hook a specific setup into one of the elements \xmlgrab{main}{cd:command}{cd-demo} This setup is (here #1 represents the current node): \startxmlsetups cd-demo \NC \xmlatt{#1}{name} \NC \xmlatt{#1}{file} \NC \NR \stopxmlsetups Now we can say: \starttabulate[|l|l|] \NC command \NC file \NC \NR \xmlall{main}{//cd:command} \stoptabulate This gives us a two column table There is a truckload of (to be documented) commands, for instance one can filter wlements with: first \xmlfilter{main}{cd:command/first()} \blank[2*big] last \xmlfilter{main}{cd:command/last()} \blank[2*big] first \xmlfirst{main}{cd:command} \blank[2*big] last \xmllast {main}{cd:command} \blank[2*big] You can flush whole (sub)trees, access elements by index, etc A variant of the table builder (without the need for adding hooks) is \startxmlsetups cd-demo \NC \xmlatt{#1}{name} \NC \xmlatt{#1}{file} \NC \NR \stopxmlsetups \starttabulate[|l|l|] \NC command \NC file \NC \NR \xmlcommand{main}{//cd:command}{cd-demo} \stoptabulate Or: \startxmlsetups another-demo \NC \xmlatt{#1}{name} \NC \xmlatt{#1}{file} \NC \NR \stopxmlsetups \starttabulate[|l|l|] \NC command \NC file \NC \NR \xmlfilter{main}{//cd:command/command('another-demo')} \stoptabulate I reimplemented the presentation mml module (partially) using this mechanism. The regular definitions still work but processing a file is done differently: \xmlprocess{id}{filename}{optional initiaization setup} It probably takes a while to get accustomed to this, but this mixture of stream and tree handling of xml files looks promising. The current functionality is still experimental and details may change but the base is there.

Hi, I could not figure out how to add a hairline between two rows of a matrix. Following example is compiling but only results in a bigger vertical space.

fonts from scratch: what's the way?
by Andrea Valle 04 Sep '07

04 Sep '07

Hi to all, after some "eccentric" projects (musical notation, presentations, posters...) I'm starting my first "core" project with ConTeXt. We have a review here at the university which has been published until now by a publisher. As we are having bad typography and bad distribution, and, more, we have to pay for these two services, we are moving it to the web as a series of downloadable pdfs (maybe with Lulu support). Obviously I've proposed ConTeXt. Now: - I think I can manage the project organization as I have already done it for other projects following http://wiki.contextgarden.net/Project_structure - I think I can define style, format etc using the manuals and the list archive and support But: Fonts are really a mysterious topics. Because of this facts, I have always used default ones. As far as I have understood, The Mk IV issue should simplify the situation but (I really don't want to be indelicate) this is really a horror film for a newbie: http://wiki.contextgarden.net/Mark_IV I'm using TeXLive installation on a macosx (mactex: http:// www.tug.org/mactex/) So: - should I know something about the metrics and other trickery? In that case, really a picture is worth ten thousand words. - how do I know which fonts are installed by the distro? AFAIK, it seems that this is a fairly complicated topic. Which seems to be pretty bizarre, because if they are unusable, why should they be installed? Experimenting with \enableregime[mac] \usetypescript[berry][ec] % or [8r] \usetypescript[palatino][ec] % \definetypeface[bookman][rm][serif][bookman][default][encoding=ec] \usetypescript[berry][ec] % or [8r] \definetypeface[charter][rm][serif][charter][default][encoding=ec] \starttext \setupbodyfont[palatino] çèòîàùé \setupbodyfont[pos] çèòîàùé \setupbodyfont[bookman] çèòîàùé \setupbodyfont[charter] çèòîàùé \stoptext (from http://home.salamander.com/~wmcclain/context-help.html#intro) Seems to work but I don't know why and how... - so, excluding "secret" pre-installed fonts, what I have to do to choose a (free) font ? - and how do I install it on my machine? - I.e.: what have I to do? Stay on mark II or switch to mark IV? This "mark" issue has confused me a lot more...:) I think a real tutorial on the font subject is lacking. All the available infos () in some way require IMHO a relevant knowledge So I am solemnly saying that I will wikify the discussion... Many thanks Best -a- -------------------------------------------------- Andrea Valle -------------------------------------------------- CIRMA - DAMS Università degli Studi di Torino --> http://www.cirma.unito.it/andrea/ --> andrea.valle(a)unito.it -------------------------------------------------- I did this interview where I just mentioned that I read Foucault.
