unwanted rgb-->gray conversion (mkiv)
by Peter Rolf 03 Feb '09

03 Feb '09

Hi Hans, The attached example works fine with mkii (text and gfx both use RGB colors). Using mkiv reduces the colorspace of the graphic to GRAY. Sadly PDFX/-4 doesn't allow to mix color profiles of colorspace RGB with GRAY ones. So I'm forced to always use the RGB colorspace... Best wishes, Peter \setupcolors[state=start] \definecolor[rgbgray] [r=.5,g=.5,b=.5] \startuniqueMPgraphic{foo}{size} fill unitsquare xyscaled(\MPvar{size},\MPvar{size}) withcolor \MPcolor{rgbgray}; \stopuniqueMPgraphic \starttext \uniqueMPgraphic{foo}{size=5cm} \color[rgbgray] Gray text. \stoptext

Any ConTeXt user with ancient linux distribution?
by Mojca Miklavec 03 Feb '09

03 Feb '09

Hello, The new server on contextgarden.net has a newer linux distribution and 64-bit kernel. I used to compile the linux binaries on the server since they worked everywhere, also on newer machines (I once wrote a note "compiled with glibc 2.3.6" and maybe the kernel was 2.4.something; it was debian etch). The vice versa doesn't hold - if we compile the binaries on some newer machine, they won't work on older linuxes. So I have two questions: - Are there still users with old linux distributions using the minimals? - And if yes - any volunteer to compile the binaries on regular basis? (The releases of new luatex are the most critical ones. Other binaries can usually wait longer.) You may write me off-list. Mojca

Possible memory leak?
by Yue Wang 02 Feb '09

02 Feb '09

Hi, Hans: in font-afm.lua, you use fontforge to open and to_table a pfb, but without closing it? btw, when MKIV is running for the first time (i.e., no cache file). it will use a lot of memory (parsing a 10M font will use 700-800 MB memory), are there some ways to reduce that? Another problem is, the memory usage seems incremental: I watch the memory usage in "top" carefully, it does not reduce when MKIV finish reading and caching an otf font. (well I read the font-otf.lua, and you are actually closing that font. so maybe that's because luatex is leaking memory?) btw, I load arial 300 times using the following file, %engine=luatex \directlua0{ function load_font (filename) local metrics = nil local font = fontforge.open(filename) if font then metrics = fontforge.to_table(font) fontforge.close(font) end return metrics end myfont = load_font('arial.ttf') % 300 myfont = load_font('arial.ttf') myfont = load_font('arial.ttf') myfont = load_font('arial.ttf') myfont = load_font('arial.ttf') myfont = load_font('arial.ttf') } and I can see the memory usage may ebb and flow, but actually it is leaking memory.

Third International ConTeXt meeting 2009
by Taco Hoekwater 02 Feb '09

02 Feb '09

Hi all, I want to remind you of the Third International ConTeXT meeting that will be held in the Netherlands from August 31 to Sept 4, 2009. Please note that the dates have changed, the meeting will be held one week later than originally announced. There is no finalized programme yet, but we that there will be parallel LaTeX and ConTeXt sessions for the tutorials and macro- package specific talks, besides combined developer presentations. Separate rooms for informal discussions and workshops will be available throughout the week. Presentation proposals and topic requests are (of course) very welcome. The conference theme is "Educational Uses of TeX", so anything on that topic is exceptionally welcome, but that does not prohibit other topics. Please feel free to contact me! The joint eurotex conference and context meeting is made possible by the Netherlands Defence Academy (NLDA) that graciously invited us to their facilities, including the on-site hotel. This makes it possible to have a very competitive conference fees. The entire five-day meeting including six overnight stays in a single room, all meals, the conference materials, and a full day day excursion with following conference dinner will cost only 425 euro (for LUG members). For quick deciders, the 100 euro early bird discount offer deadline has been extended a bit, that is valid for another two weeks from today (until Feb 15). See the website for (some) more information and registration: http://www.ntg.nl/EuroTeX2009 Hope to see you there, Taco Hoekwater (for the organizing committee)

How to capture a typeset page into a box instead of shipping it out
by Kevin D. Robbins 01 Feb '09

01 Feb '09

Hi all, I am looking for ideas of how to capture a typeset page (as it would appear in the resulting pdf output) into a box instead of actually shipping it out directly, if it is possible. I would like to take advantage of ConTeXt's layout features including layers, otherwise I would just create the box with \setbox. My intent is to draw slides using all of ConTeXt's many layout features, but capture the rendered slide in a box so I can use it either as a full page in the presentation output or as a scaled image included as a figure in a full text "train the trainer" document. Thanks, Kevin Robbins

stupbackgrounds and margin
by Antoine Junod 01 Feb '09

01 Feb '09

Hello, list! I'm struggling to try to do something that seems simple but I'm not able to succeed. I would like to have the left margin of my document painted in red (or another color, I don't mind right now). Here is what I have: \setuppapersize[A5][A4] \setuparranging[2UP,rotated,doublesided] \setuplayout[margin=18mm, width=middle,height=middle, topspace=0cm,backspace=18mm] \setupcolors[state=start] \setupbackgrounds[text] [leftmargin] [background=color,backgroundcolor=red] But it makes as if I had no leftmargin. What am I doing wrong? Thanks for your help, A+ -AJ

XeTeX and/or LuaTeX?
by J.A.J. Pater 01 Feb '09

01 Feb '09

I'm was planning to write my master thesis in XeLaTeX until I discovered that ConTeXt can use the XeTeX engine. I need to use a lot of Hebrew - so Right to Left typing - and some linguistic glyphs and stuff. But from the wiki I understand there are still some issues with ConTeXt's XeTeX-awareness. Like the bookmarks "may result in some strangeness in certain documents" Can someone tell me what kind of strangeness? And XeTeX can't use "certain specials and other types of features" Can someone tell me what kind of "specials and types of features"? And now on this list there is a lot of talk about LuaTeX and Mark IV. So I wonder: Is it possible to use MarkIV and XeTeX engine at the same time? And if not, why should (or shouldn't) I use MarkIV over XeTeX? Thanks in advance, Adriaan Pater

setuphead question
by Alan Stone 31 Jan '09

31 Jan '09

Hello, In the example below... ---------------------------------------------------- %\def\myCommand#1#2{} \def\myCommand#1#2{#1 #2} %\def\myCommand{} \setuphead[chapter] [number=yes, align=middle, % anyotherparameter=whatever, command=\myCommand] % command=] \starttext \startfrontmatter %\placecontent \completecontent \stopfrontmatter \startbodymatter \chapter{chapter one} \dorecurse{5}{\input tufte\par} \chapter{chapter two} \dorecurse{5}{\input douglas\par} \stopbodymatter \stoptext ---------------------------------------------------- ... how do you define myCommand so \setuphead[chapter] [(any other parameter settings), command=\myCommand, (any other parameter settings)] is equal to \setuphead[chapter] [(any other parameter settings), command=, (any other parameter settings)] i.e. with any other parameter settings remaining active. In the example above, with align=middle and - \def\myCommand#1#2{} the ToC and chapter heads are blank - \def\myCommand#1#2{#1 #2} the ToC and chapter head alignment is lost - \def\myCommand{} the ToC and chapter head alignment is lost Thanks, Alan

Minimals and dvipng
by Jean Magnan de Bornier 30 Jan '09

30 Jan '09

Hi all, My TeX setup: TeXLive (systemwide) for evetything but ConTeXt, and the minimals for ConTeXt, in my userspace. I have some issues using dvipng with minimals. I first compile this file with texexec: ...................... \setupoutput[dvi] \enableregime[utf] \starttext \startTEXpage $ SP=\int_0^{Q_0}(p_0-Cm(Q))dQ $ \stopTEXpage \stoptext ...................... In the minimals environment, dvipng says: ...................... This is dvipng 1.11 Copyright 2002-2008 Jan-Ake Larsson dvipng warning: cannot find ps2pk.map, nor psfonts.map [1dvipng warning: font rm-lmr12 at 400 dpi not found, characters will be left blank dvipng warning: font rm-lmr7 at 400 dpi not found, characters will be left blank dvipng warning: font rm-lmr9 at 400 dpi not found, characters will be left blank dvipng warning: unable to draw glyph 61, skipping dvipng warning: unable to draw glyph 48, skipping dvipng warning: unable to draw glyph 48, skipping dvipng warning: unable to draw glyph 40, skipping dvipng warning: unable to draw glyph 48, skipping dvipng warning: unable to draw glyph 40, skipping dvipng warning: unable to draw glyph 41, skipping dvipng warning: unable to draw glyph 41, skipping ] ...................... And the output is awful!! But if I dvipng in the TL environment, it works like a charm. So what should I add to my minimals install, or do to have all the TL stuff not forgotten when I use minimals? tia, -- Jean
