two questions for the simplest slides
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
Hi Pablo, for each defined colour there is a command that can be called to switch. \centerbox centres the text vertically. It is not the most elegant solution, but the following does what you asked for. \setuppapersize [S6] [S6] \setuppagenumber [state=stop] \setupbackgrounds [page] [background=color] \define[1]\setpagecolor {\setupbackgrounds[page][backgroundcolor=#1]} \setupalign [middle] \starttext \setpagecolor{blue} \yellow \centerbox{Page is blue and text is yellow.} \stoptext Marco

Thank you, Marco, for your reply. Your color information and switches are what I was looking for. \centerbox does the work, but I forgot to mention that sometimes a word per line (something line digital\\privacy). But Peter's approach solves this. Many thanks for your help, Pablo -- http://www.ousia.tk

Quick hack: \definecolor[MyColor][white] \setupbackgrounds[page][background=color, backgroundcolor=MyColor] \def\Slide#1#2#3{% #1: background, #2: foreground, #3: words \definecolor[MyColor][#1] \startstandardmakeup \setupalign[middle]% \setupcolors[textcolor=#2]% #3 \stopstandardmakeup } \starttext \Slide{red}{white}{Page is red and text is white.} \Slide{blue}{yellow}{Page is blue and text is yellow.} \stoptext Be patient, others (Wolfgang?!) will probably post cleaner solutions. -- Peter

Thanks for your reply, Peter. I have realized that your hack centered multiline slides and that I have implemented it through a \starsld...\stopsld environment (since I don't need to setup colors for every single slide). Many thanks for your help, Pablo -- http://www.ousia.tk

You mean something like this? \setuppapersize[S6] \definelayout[slide][page] \definemakeup[slide][align=middle,backgroundcolor=lightgray] \setupbackgrounds[page][background=color,backgroundcolor=\makeupparameter{backgroundcolor}] \starttext \startslidemakeup Page is gray and text is black. \stopslidemakeup \startslidemakeup[backgroundcolor=red,color=white] Page is red and text is white. Newline \stopslidemakeup \startslidemakeup[backgroundcolor=blue,color=yellow] Page is blue and text is yellow. \stopslidemakeup \stoptext Wolfgang

Many thanks for your reply, Wolfgang. I mean something like that, but I have problems when adding such an xtable: \startxtable[option={stretch,width},frame=off,split=yes] \dorecurse{100}{ \startxrow \startxcell right \stopxcell \startxcell left \stopxcell \stopxrow} \stopxtable The xtable itself won't be aligned when I set split=yes and won't be split in pages. BTW, how can I make that the first column are aligned to the right? \setupxtable[xcell][1][align=right] doesn't seem to work. Many thanks for your help, Pablo -- http://www.ousia.tk

The xtable itself won't be aligned when I set split=yes and won't be split in pages.
The makeup environment creates a page sized box which doesn’t allow material which is split over many pages. When you have such a large table you have to use a different implementation but maybe it’s better to look if you can reduce the size of the table and or to use multiple columns (the new mixedcolumns environment can be also used in a box).
BTW, how can I make that the first column are aligned to the right? \setupxtable[xcell][1][align=right] doesn't seem to work.
Xtables don’t provide the same method as natural tables to set value for individual rows or columns, you have to apply the setting to each cell or cell group (can be a direct setting via key-val or a named setting). Wolfgang

Many thanks for your reply, Wolfgang, I'm afraid I can't reduce the size or use multiple columns without rendering the text to be unreadable. All I need is that any material on the slides is centered both vertically and horizontally and can be split over pages if needed. Is there any way to get this?

\startxcell[align=right] right \stopxcell doesn't change alingment. Many thanks for your help, Pablo -- http://www.ousia.tk

\startxcell[align=right] right \stopxcell doesn't change alignment.
\startxcell[align=flushright … \stopxcell or \definextable[right][align=flushright] \startxcell[right] … \stopxcell That’s explained in the manual. Wolfgang

Many thanks for your help, Wolfgang. Sorry, I searched the manual for this information earlier this morning and I didn't find it. BTW, thank you again for proposing a different approach to the horizontally and vertically centered slides. This does the job for me: \setupalign[middle] \definestartstop[slide][before=\page\mbox{}\vfill\mbox{},after=\vfill\vfill] Thanks again for your help, Pablo -- http://www.ousia.tk

All you need, can be done with \framed: \setuppapersize[S6] \setuplayout[page] \def\Slide#1#2#3{% #1: background, #2: foreground, #3: words \framed[offset=overlay, width=\textwidth, height=\textheight, background=color, backgroundcolor=#1, foregroundcolor=#2, align={middle, lohi}, frame=off]{#3}} \starttext \Slide{red}{white}{Page is red and text is white.\\Newline} \Slide{blue}{yellow}{Page is blue and text is yellow.} \stoptext -- Peter

Sorry, Peter, I haven't expressed myself accurately. \def\Slide#1#2#3 has a problem, namely, that I have to enter both background and foreground colors for each single slide. \definestartstop[sld][before={\page\startstandardmakeup\setupalign[middle]},after=\stopstandardmakeup] makes easier to change colors only when I really need it.
