two questions for the simplest slides
by Pablo Rodríguez 22 Jul '12

22 Jul '12

Hi there, I would like to create the simplest slides ever. I have done in LaTeX before, but I'm not sure how to do it with ConTeXt. All I want is to be able to center both vertically and horizontally whatever each slide contains and to change background and text colors in an easy manner (something like from now on background is red and text is white). Looking to http://tug.org/pracjourn/2006-2/schmitz/ and http://wiki.contextgarden.net/Presentations, I still have two questions. How can I get every single slide, no matter there is text or images, vertically centered? How can I change background and text colors after a \page? I mean something like: \setuppapersize[S6][S6] \setupcolors[state=start] \setuppagenumber[state=stop] \setupbackgrounds[page][background=color,backgroundcolor=red] \startcolor[white] \starttext Page is red and text is white. \page Page is blue and text is yellow. \page Page is green and text is white. \page Page is white and text is black. \page Page is red and text is white (again). \stoptext I mean, I know how to start, but I don't know how to change after the start. And it would be extremely helpful to change text colors with a switch (if that were possible), not within an environment (mainly because most slides will only contain one of two words). Many thanks for your help, Pablo -- http://www.ousia.tk

Re: [NTG-context] simpleslides help needed

Hi Pavneet, I am CCing the list as others might find this useful as well.

This is > why I tried \setupbodyfont and ran into my initial difficulties. Use \setupSlideTitle [style={ any font command }] The default value of style is \switchtobodyfont[\SlideTitleSize]. The easiest way to switch fonts is to use \definefont or, if you are using the simplefonts module, \definesimplefont. For example: \usemodule[simpleslides] \usemodule[simplefonts][size=\NormalSize] \definesimplefont[SlideTitleFont][Dejavu Sans][size=\SlideTitleSize] \setupSlideTitle[style=\SlideTitleFont] \starttext \SlideTitle{Knuth} \input knuth \stoptext

italic corrrection?
by Meer, H. van der 21 Jul '12

21 Jul '12

I cannot see the italic correction. Neither in the default not, nor in lucidaot. An explicit \/ (plain TeX material!) makes no difference. Addition of \setupitaliccorrection[always] also did not make a difference. What am I doing wrong? Hans van der Meer % italic correction \setuppapersize[A6][A6] %\setupbodyfont[lucidaot] \starttext {\it n}:{\it n}\crlf {\it n\/}:{\it n}\crlf \stoptext

report of strange(?) output depending on the location of \StartSteps ... \StopSteps
by dalyoung 21 Jul '12

21 Jul '12

Dear all, This is a small thing which is OK to be ignored. Please pardon me if it is a noise for you. I used to use \usemodule[pre60] for step by step output for presentation. Some time ago, I faced a strange pdf output. For example, I want two steps inside the second item. So, I use the following: \usemodule[pre60] ... ... Test of \tex{StartSteps}. \blank \startitemize \item first item \item second item \StartSteps \startitemize \item flush 1 \FlushStep \item flush 2 \FlushStep \stopitemize \StopSteps \item third item \stopitemize \page \starttable[|c|c|c|c|c|c|] \HL \VL \VL A \VL B \VL C \VL D \VL E \VL\FR \HL \VL \VL 2\VL 1\VL 3\VL 2\VL 2\VL\SR \HL \stoptable ... %%%%%%%%%%%% I got correct steps flush1 and flush 2, but the table after the steps was disappeared.(just white page) If I change the order of table and items, both are displayed and worked well. I have tested in many ways to know why the table disappeared after \StartStep. I found that it is neither the order of the code nor the some other settings. It is the level of the location of \StartSteps. If I put \StartSteps in the first level of itemization, there is no problem. Of course, I have to put more \FlushStep like Test of \tex{StartSteps}. \blank \StartSteps \startitemize \item first item \item second item \FlushStep \StartSteps \startitemize \item flush 1 \FlushStep \item flush 2 \FlushStep \stopitemize \StopSteps \item third item \FlushStep \stopitemize \page \starttable[|c|c|c|c|c|c|] \HL \VL \VL A \VL B \VL C \VL D \VL E \VL\FR \HL \VL \VL 2\VL 1\VL 3\VL 2\VL 2\VL\SR \HL \stoptable I report this just for information which may be already known to Hans, Wolfgang, et al. One appreciation is that \StartSteps ... \StopSteps works well with Simpleslides module nicely! Thanks and have a nice weekend. Best regards, Dalyoung

space around formula
by Meer, H. van der 20 Jul '12

20 Jul '12

The space around formula with \placeformula is a bit too large to my taste, even in the case of \setupformulae[spaceafter=small]. Because setting this to 0pt didn't make much difference, I had to resort to spaceafter=-1ex. Why is there seemingly always such a large space around the formula? Why not a much tighter boundary? Furthermore, it seems that there is no difference like above/below-displayskip and ditto displayshortskip as in Plain TeX. At least, I could not find it. Or did I miss that? I consulted the wiki, but the information is not found. Hans van der Meer

figures: side by side and/or one above the other
by d_jan 20 Jul '12

20 Jul '12

Hello, I'm using context for an document with many figures. In some cases I have figures that should appear side by side and/or one above the other – but without combining them (\startcombination... \stopcombination). This I want to avoid because I'd like to give them a plain caption (like non-combined images) and because I would not like putting not directly related figures in a combination. In addition, when placed [left], combinations somehow center all sub-captions, though for single images they are left-aligned. (see http://pastebin.com/tZiNuekZ) Here is what I tried (and what went wron on the way) A) one above the other – so that I have the images on the left side of the page, while the text is on the right. I tried to archive this using the attribute [left]. The text floats aside of the one bottom image (someimage2), but not aside the one above it (someimage1). This code produces a working example: \starttext \placefigure [left] {caption} {\externalfigure[someimage1][width=0.5\textwidth]} \placefigure [left][fig:newton] {caption} {\externalfigure[someimage2][width=0.5\textwidth]} \input tufte \stoptext B) side by side I tried to work with columns here, but i was not successful. The figures often went not together and when a setup worked, the text did not continue to flow after the images but was starting on the next page. I hope there is a more robust solution out there. I would be grateful if somebody could point me in the right direction for solving these issues. Regards, Jan

Adding command pages to the wiki
by Sietse Brouwer 20 Jul '12

20 Jul '12

Hi all, When some command is mentioned on this mailing list, and people say "somebody might want to add this information to the wiki", and the command page doesn't even *exist* yet — don't despair. Creating it is easy, now. * There's a proper copy-paste skeleton for new command pages, now; you can copy it and fill in what you need with a minimum of fuss. It lives at http://wiki.contextgarden.net/Help:Command_reference. * Help:Command_reference is now linked from the [[Category:Commands]] page, so it should be easy to find when you need it. * No more interleaving your prose with <code> and <tt> tags: {{cmd|defineparagraphs|[LeftRight]}} produces a linkified and typewriter-fonted \defineparagraphs[LeftRight]. * Link to up-to-date versions of source files with {{src|m-ipsum.mkiv}}. This links to the repository at http://repo.or.cz/w/context.git. * Mark code with {{code|...}} instead of <code>...</code>. It codes the same thing, but it's easier to type. (And easier to recode what it encodes. Code code code.) Speaking of the command reference: if you click on http://wiki.contextgarden.net/Category:Commands, you'll see that there are only 100 commands left to categorize. Some help would really be appreciated at this stage. Just open two or three commands in tabs, and change [[Category:Commands|mycommand]] to [[Category:Command/SubCategory|mycommand]]; you can see the list of subcategories at the top of the Category:Commands page. Kind regards, Sietse (Esteis on the wiki)
