Dear ConTeXt list, This could be more of a style and TeX question than a ConTeXt question. Nevertheles: I am making a presentation that involves some simple animations. The way I make those animations is by: 1. Stopping page numbering. 2. Flipping through the same slide repeated, but with img0, img1, img2 etc. 3. Start page numbering. The problem with my naïve approach of repeating slides is that fixing a spelling error or making changes implies that I have to do it several times for an “animated” slide, and is error-prone. Could you point me to a way by which I can make a slide something like a “function” whose argument is the image, and calling it creates that slide with an image? FWIW, I use texexec --xtx, but I am guessing a LuaTeX solution would be simpler. The XeTeX solution is what I am not able to find now. Thanks! Kumar -- Kumar Appaiah

You could use buffers: \newdimen\cnt \starttext \startbuffer [greenbar] \blackrule[width=4cm, height=5mm, color=green] \stopbuffer \dorecurse{10}{%% \blackrule[width=\textwidth] \advance\cnt1cm \hskip\cnt \getbuffer[greenbar]\page} \stoptext Marco
Hello Kumar. I make my PDF animations so that I first create a single multi-page PDF file whose separate pages are separate animation frames. Then this auxiliary PDF file I put into another PDF file using \ fieldstack. Here's how I prepare a separate animation file. \def\setmyparameter#1#2{% \global\def\myparameter{#2}#1% }% \def\processmyparameters[#1]#2% {\processcommalist[#1]{\setmyparameter{#2}}} \startbuffer [greenbar] \blackrule[width=\myparameter, height=5mm, color=green] \stopbuffer \starttext \processmyparameters[1cm,2cm,3.5cm,4.5cm,8cm,11cm]{ \getbuffer[greenbar]\page} \stoptext Greetings Jaroslav Hajtmar Dne 20.2.2013 10:16, Marco Patzer napsal(a):
\newdimen\cnt \starttext
\startbuffer [greenbar] \blackrule[width=4cm, height=5mm, color=green] \stopbuffer
\dorecurse{10}{%% \blackrule[width=\textwidth] \advance\cnt1cm \hskip\cnt \getbuffer[greenbar]\page}

Thank you for this solution. I just tried this, and this works well for me as well! Kumar -- Kumar Appaiah

This is a lovely solution, and I'll put off learning LuaTeX for now. Thanks! :-) Kumar -- Kumar Appaiah
