Layers for absolute positioning
by Curiouslearn 07 Mar '11

07 Mar '11

Hi, I have been trying to learn the best way to position text on a page. >From the messages it appears that a good way to do so, is to use layers. But it seems that to activate them I need to set them as background of the page. However, that removes the background color. How can I get both layers and a background color? I have given a minimal example below. Thanks, Bharat This is the minimal example I am working with: \setupcolors[state=start] \setupcolor[xwi] \setupbackgrounds[page][background=color, backgroundcolor=linen] \starttext \definelayer [windows] [x=3in, y=3in, width=3in, height=4in] \setlayer [windows] [hoffset=1cm, voffset=1cm] {Windows 7} \setupbackgrounds[page][background=windows] \page[empty] \stoptext

Re: [NTG-context] font name has a space.

Dear Taco, Thank you for your comment. I renamed the font to ~.ttf, luatools --generate first. And try the same file. At this time, there is no "Fatal error messages", but still it doesn't locate the font file. So, I tested a few more things. Test 1: luatools locates all the fonts which has no space from the same font maker. And, LuaTeX runs well to yield fine output. Math-iMac:~ graph$ luatools 산돌돌CB.otf /Users/graph/Library/Fonts/산돌돌CB.otf Math-iMac:~ graph$ luatools 산돌명조B.otf /Users/graph/Library/Fonts/산돌명조B.otf ####### Test 2: luatools cannot locate the fonts which has space from the same font maker. Math-iMac:~ graph$ luatools 산돌명조M.otf Math-iMac:~ graph$ luatools 산돌명조 M.otf Math-iMac:~ graph$ luatools 산돌명조\space M.otf But it locates the same file if I enclose "font name". Math-iMac:~ graph$ luatools "산돌명조 M.otf" /Users/graph/Library/Fonts/산돌명조 M.otf So I tired \definefont[testfont][file:"산돌명조 M.otf"], but LuaTeX issue an error system > begin file testmp.tex at line 29 ! LuaTeX error <main ctx instance>:1: ')' expected near '?'. system > tex > error on line 30 in file testmp.tex: LuaTeX error ... 25 26 \definefont[testfont][file:"산돌명조 M.otf"] 27 28 29 \starttext 30 >> \testfont 31 \chapter{X} 32 \section{One} 33 \dorecurse{10}{test fone file. } 34 \dorecurse{10}{산 돌 명조 폰트 file입니다. } 35 36 \stoptext \lowleveldefinefont ...ies ", "\@@fontgoodies " )} \edef \somefontspec {at \n... \dododefinefont ...inefont {#2}\rawfontidentifier \csname \rawfontidentifier... l.30 \testfont ? I tested english font which has a space in its name and got the same results. For example, "Geogia Bold.ttf" font. luatools cannot locate it and LuaTeX said "unknown font." and used default font. I renamed it GeogiaBold.ttf in /Library/fonts and tried again, but not succeed. Hence, I think that the font whose name contains no space has no problem. The fonts whose name contains a space make a trouble eventhough I removed the space from it. Am I doing right? I am using Mac OSX. And, This is LuaTeX, Version beta-0.65.0-2010121316 \write18 enabled. (testmp.tex ConTeXt ver: 2011.02.25 22:03 MKIV fmt: 2011.3.1 int: english/english Thank you again. Best regards, Dalyoung

problem with tikz remember picture and overlay.
by Curiouslearn 07 Mar '11

07 Mar '11

Hello, I am trying to use tikz's remember picture and overlay for absolute positioning. With the code below, the content in the tikz picture appears on a new page after the slide title. I want it to appear on the same page. Please see the minimal example below. I have explained with comments where the problem occurs. Thanks for your help. \setuppapersize[S6][S6] \setuplayout[backspace=0.5in, width=middle, header=0.25in, topspace=0.25in, height=middle] \setupbackgrounds[page][background=color, backgroundcolor=linen] \setupwhitespace[medium] \setuppagenumbering[location=] \setupcolors[state=start] \setupinteraction[state=start,color=blue] \setupcolor[xwi] \definehead[slidetitle][subject] \setuphead[slidetitle][style=\tfb, color=lightsteelblue] \def\SlideTitle#1{\page\framed[frame=off, background=color, % backgroundcolor=gray:9]{\slidetitle{#1}}} \usemodule[simplefonts] \setmainfont[Helvetica] \switchtobodyfont[20pt] \definehead[slidetitle][subject] \setuphead[slidetitle][style=\tfb, color=lightsteelblue] \def\SlideTitle#1{\page\framed[frame=off, background=color, % backgroundcolor=gray:9]{\slidetitle{#1}}} \starttext \SlideTitle{Product Characteristics and Quality} % This tikz content should appear on the same page as the title, but it appears % on a new page. If I use \subject{Product Characteristics and Quality} then % the tikz content appears on the same page. \starttikzpicture[remember picture, overlay] \node[xshift=2in, yshift=2in] at (current page.north west) [text width = 2in]{Weight?} \stoptikzpicture % The following content appears on another page after the tikz content. This is independent % of whether I use \SlideTitle or \subject. How can I make all of these appear on the same page? MORE CONTENT HERE \stoptext

grid
by Matthias Vettel 07 Mar '11

07 Mar '11

Dear ConTeXt users, I did some experimenting with grids and there is one thing that puzzles me: when I switch between one and two columns as in the following example ///////////////////////////////////////////////////////////////// \setuplayout[grid=yes] \setupcolumns[n=2] \starttext \showgrid Hello! \startcolumns Hello! \stopcolumns Hello! \stoptext ///////////////////////////////////////////////////////////////// the last line isn't placed on the grid. What am I missing? (I used luatex 0.66 and mkiv). Kind regards, Matthias Vettel

Re: [NTG-context] slide steps again

Hi, If you want to reveal parts of a drawing sequentially, you may try MetaFun and AdobeReader. There is a sample in 13.6 Growing graphics, metafun manual(metafun-p). It needs your time but the result is very nice. I hope you enjoy it. Best regards, Dalyoung

Re: [NTG-context] font name has a space.
by Jeong Dalyoung 07 Mar '11

Dear Hans, After removing space in the name, LuaTeX locates the font. However, I couldn't get an output. There is a fatal error message as following: )</Users/graph/Library/Fonts/smMokPan Medium.otf !LuaTeX error (file /Users/graph/Library/Fonts/smMokPan Medium.otf): Invalid character. ==> Fatal error occurred, no output PDF file produced! There may be some problems in the font file. But, it was working well in other editing programs. I'd like to tell to font maker about this error. On the while, Is there a way to get a detailed information on the "Invalid character" error ? Thank you for your help. Best regards, Dalyoung

structure head alignment nullifies spaceskip
by Philipp Gesang 06 Mar '11

06 Mar '11

Hi, is there a way to have \spaceskip working in a centered section head? I have something similar to these exaggerated values: ··8<····························································· \def\broadspacing{% \dontleavehmode% \spaceskip 1em plus .5em minus .5em% } \starttext \setuphead[section][% style={\WORD\broadspacing}, ] % This one is left aligned but correctly spaced. \section{test test test} \setuphead[section][% style={\WORD\broadspacing}, align=middle, ] % This one is centered but spaced too tightly. \section{test test test} \stoptext ··8<····························································· As you can see, adding “align=middle” to the section setup leads to the \spaceskip setting being ignored. Any idea how to space my capitalized words in section heads? Thanks very much, Philipp

Where is bibmod searching for bibliography style files?
by Florian Wobbe 06 Mar '11

06 Mar '11

Hi, I created a custom bibliography style file (bibl-mybst.tex) and like to use it with \setuppublications[alternative=mystyle] For obvious reasons I want to move the file from texmf-context/tex/context/bib to some directory in texmf-local. Unfortunately, the file is not found in the texmf-local tree. I have tried several subdirectories using MkIV. Where should the file go so that bibmod finds it? Thanks, Florian

One-off theorem titles
by S Barmeier 06 Mar '11

06 Mar '11

Currently I am using something like \defineenumeration[lemma] [location=serried, headstyle=bold, text=Lemma, width=broad, style=italic] to define theorems, lemmas, etc. Sometimes a theorem or lemma will have its own name (e.g. Yoneda Lemma), and I find it slightly cumbersome to write something like 3.1 Theorem (Yoneda Lemma) 3.1 Lemma (Yoneda) 3.1 Lemma (Yoneda Lemma) and was really hoping that \startlemma[text={Yoneda Lemma}] would give me the desired 3.1 Yoneda Lemma but it doesn't. I would like to keep the whole setup the same and only change the text for this instance. Is there any way to implement this except for defining a whole new enumeration for one theorem/lemma/proposition by \startenumeration[text={Yoneda Lemma},location= ... ] Thank you. Severin

automatic filename extension with \externalfigure
by Florian Wobbe 06 Mar '11

06 Mar '11

Hi, I have an image file with two dots: file.xy.pdf I can embed this file with \externalfigure[file.xy.pdf][][width=\textwidth] When leaving out the extension, the image is not found, e.g.: \externalfigure[file.xy][][width=\textwidth] For the time being, I renamed the files but it would be great if multiple dots in filenames were supported. Thanks, Florian
