Flaky pdf file.
by John Culleton 27 Sep '08

27 Sep '08

Recent texlive 2008 installed on Linux Slackware 12.0 system. I have a file that I can process via texexec and which shows up fine on my Acrobat Reader, kpdf or xpdf. However another person using (probably) Windows keeps getting corrupt file errors when he tries to read it. And when I try to run the output pdf through pdf2ps it blows up with this message: --------------------------------------------------------------------------------- **** Warning: An error occurred while reading an XREF table. **** The file has been damaged. This may have been caused **** by a problem while converting or transfering the file. **** Ghostscript will attempt to recover the data. ERROR: /undefined in /BXlevel Operand stack: 1 --dict:6/6(ro)(G)-- 8¬ÎµÈ¶dm Execution stack: %interp_exit .runexec2 --nostringval-- --nostringval-- --nostringval-- 2 %stopped_push --nostringval-- --nostringval-- --nostringval-- false 1 %stopped_push 1 3 %oparray_pop 1 3 %oparray_pop 1 3 %oparray_pop --nostringval-- --nostringval-- --nostringval-- --nostringval-- --nostringval-- --nostringval-- false 1 %stopped_push --nostringval-- %loop_continue --nostringval-- Dictionary stack: --dict:1119/1686(ro)(G)-- --dict:0/20(G)-- --dict:107/200 (L)-- --dict:107/200(L)-- --dict:104/127(ro) (G)-- --dict:241/347(ro)(G)-- --dict:18/24(L)-- Current allocation mode is local ESP Ghostscript 815.04: Unrecoverable error, exit code 1 --------------------------------------------------------------- Other pdf files on my system, built on other computers etc. process fine through pdf2ps. I took out all the advanced stuff, such as bookmarks, interaction and urls but I still get the same kind of error. An old pdf version of the file, dating back to February, also blows up. The preamble to the file plus dummy text looks like this: -------------------------------- \setupoutput[pdftex] \setupindenting[none] \setupwhitespace[medium] \frenchspacing \setupcolors[state=start] \setuphead[chapter][head=nomarking,number=no] \setuphead[section][number=no,textcommand=\bf] \setuphead[subsection][number=no] \setuphead[subsubsection][number=no] %\setupinteraction[state=start,color=blue] \setuplist[section][alternative=f,style=bold,interaction=no] \setuplist[subsection][alternative=f,interaction=no] \setuplist[subsubsection][alternative=c,interaction=no] \starttext foo \stoptext -------------- This blows up on pdf2ps also. I just created a dummy pdftex file, compiled it, then converted it with pdf2ps with no problem. Either there is an error in my preamble or something fishy with Context. Thoughts? -- John Culleton

switching (named) layouts?
by Jelle Huisman 26 Sep '08

26 Sep '08

Hi, Is it possible to give a layout definition a name? It would be really helpful to be able to say \definelayout[name=one][...] \definelayout[name=two][...] and then to be able to say: \setuplayout[one] and somewhere else in the document \setuplayout[two] (This would mirror the way it is possible to switch papersizes.) Or is there another way to have different collections of \definelayout settings that can be switched on or off at specific places? What is the best approach? Thanks, Jelle

Can we make font loading much faster?
by Yue Wang 26 Sep '08

26 Sep '08

Hi: The following cases all use second run of context. So there is no font cache time. I use a new installed Windows XP SP3 on a Core 2 Duo 1.68GHz with 1GB mem machine. Only TeXWorks and ConTeXt are installed and running on the machine. I close all pre-installed software (like MSN, IE, etc.) and leave all extra memory for LuaTeX. Only 3 big chinese font, AdobeSongStd-Light, AdobeHeitiStd-Regular, AdobeKaitiStd-Regular are loaded. However, different approaches have different runtime, here, two cases are tested (zhfonts is attached in the mail): \usetypescriptfile[zhfonts] \usetypescript[myfont] \setupbodyfont[myfont,rm,11pt] \starttext 你好 {\it 你好} {\bf 你好} \stoptext MtxRun | total runtime: 194.156 \definefontfeature[zh][mode=node, script=hang, lang=zhs] \definefontsynonym[song][AdobeSongStd-Light][features=zh] \definefont[song][song at 12pt] \definefontsynonym[hei][AdobeHeitiStd-Regular][features=zh] \definefont[hei][hei at 12pt] \definefontsynonym[kai][AdobeKaitiStd-Regular][features=zh] \definefont[kai][kai at 12pt] \starttext {\song 你好}{\hei 你好}{\kai 你好} \stoptext MtxRun | total runtime: 13.797 This also applies to file which only one big font, AdobeSongStd-Light, is used, two cases are tested: \definefontfeature[zh][mode=node, script=hang, lang=zhs] \definefontsynonym[song][AdobeSongStd-Light][features=zh] \definefont[song][song at 12pt] \definefontsynonym[hei][AdobeHeitiStd-Regular][features=zh] \definefont[hei][hei at 12pt] \definefontsynonym[kai][AdobeKaitiStd-Regular][features=zh] \definefont[kai][kai at 12pt] \starttext {\song 你好} \stoptext MtxRun | total runtime: 5.609 \usetypescriptfile[zhfonts] \usetypescript[myfont] \setupbodyfont[myfont,rm,11pt] \starttext 你好 \stoptext MtxRun | total runtime: 135.125 If no Chinese fonts are used, three cases are tested: \usetypescriptfile[zhfonts] \usetypescript[myfont] \setupbodyfont[myfont,rm,11pt] \starttext Hello \stoptext MtxRun | total runtime: 89.938 \starttext Hello \stoptext MtxRun | total runtime: 2.594 \definefontfeature[zh][mode=node, script=hang, lang=zhs] \definefontsynonym[song][AdobeSongStd-Light][features=zh] \definefont[song][song at 12pt] \definefontsynonym[hei][AdobeHeitiStd-Regular][features=zh] \definefont[hei][hei at 12pt] \definefontsynonym[kai][AdobeKaitiStd-Regular][features=zh] \definefont[kai][kai at 12pt] \starttext Hello \stoptext MtxRun | total runtime: 2.734 In a typical chinese science book, usually 4 to 10 chinese truetype/opentype font are used. Magazines might use twenty or more. So if we want to use the standard way (use chinese font as body font, use virtual fonts mechanism to mix the font with latin fonts, use different alternatives for single chinese font) as the zhfonts.tex is presented, the running time here is usually intolerable (more than 3 minutes' loading time with very simple text for three fonts). A simple XeLaTeX file with three font embeding using XeCJK or zhspacing for interchartoken font switching usually runs less than 8 seconds. In this case, all the family (rm, ss, tt) parts (like bf, it, etc) in NFSS are defined. So, I think there should be a way to improve the font loading procedure. Maybe we had made deep copy to every fontsynonym defined here which made the loading time terribly long? Are there some way to mirror all the unchanged part of a new loading font B from a loaded time A and only leave the modified table when A and B points to same physical font? Thanks. Yue Wang

Fonts: Minimals v. Texlive 2007
by Erich R Fickel 26 Sep '08

26 Sep '08

Thanks to everyone who helped me get the minimals installed. I am having a little trouble. At my home computer, I have the Context installation for Ubuntu 7.04 from the sanjoy tex-live backports. At work I now have the minimals, --context=current, not beta. I expected that the output of these two systems would be nearly identical. They are not. I do not use any special font handling. I let Context handle it all. I use whatever the default fonts are, and use \setupbodyfont only to set fontsize. The same source run on both machines produces slightly different margins and slightly different font sizes. The minimals are smaller (shorter) for the same font size (11 pt). I really would like to get the same output for both systems. Can anyone help with this? -Erich Fickel

force figure placement on this page
by Jelle Huisman 26 Sep '08

26 Sep '08

[it looks like this mail didn't make it to the list, sorry if double posted] Hi again, I try to get a picture on a page using \externalfigure[name.pdf][width=\textwidth] The image is pushed to the next page, even though there is no text on the current page and the height of the image itself is smaller then \textheight, so it should fit. How do I force image placement *here*? Thanks again, Jelle

Descriptions ... I wish I understood them
by Mojca Miklavec 25 Sep '08

25 Sep '08

Hello, I have some weird problems with descriptions, but let's start at the beginning. (I have more problems with understanding how they work, but more about the rest later.) 1.) How do I get some space between "title" and "abc"? (I currently put the space there manually.) If I set distance=1em, weird things start happening. 2.) What exactly does "hang=1" do? I have no idea what it does there, but that was the only way to get the desired result, else everything gets indented. width=fit makes problems. With width=5cm everything is OK. \definedescription [ma] [headstyle=bold, style=italic, align=left, location=left, width=fit, distance=0pt, margin=0pt, hang=1, indenting=never, ] \starttext \input tufte \startma{title} abc. \input tufte \stopma \input tufte \stoptext Thanks a lot, Mojca

How to get rid of space around itemize?
by Mojca Miklavec 25 Sep '08

25 Sep '08

Hello, I'm trying to remove space before (and after) items in the following example, but the only way I have managed to do that was by using \vskip-\lineheight, which I'm not particulary proud of. Any ideas? \setupwhitespace [big] \setupitemize [joinedup] \setuplayout [grid=yes] \showgrid \starttext How to reduce the space here? \startitemize \item a \item b \stopitemize And here? \stoptext Thanks a lot, Mojca

math font size in captions (and other places)
by Mikael Persson 25 Sep '08

25 Sep '08

Dear all, I want small caption texts in a document. However, neither of the following two alternatives work: %%%%% %\setupcaptions[style=small] \setupcaptions[style=\tfx] \starttext \placefigure[here][none]{Some math $x=y$}{Dummy figure} \stoptext %%%%% In both cases the text is small, but math font is not changed. I can solve this by doing a \switchtobodyfont in the caption, but I'd like to do it only once and for all. I guess I have the same problem in all environments where there is a style= parameter. (For now, I also would like to set it in \setupmarginblocks. I've tested this both on mkii and mkiv and with updated (minimal) ConTeXt. Best regards, Mikael Persson PS Any progress in getting the fourier (utopia+fourier) fonts to work in the new minimals? I miss that combination of fonts. I did not get the reason of why it is not included anymore.

Then there are a lot of wiki-pages wrong. Who is allowed to correct this? Wolfgang
