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):
