Subject: random background picture in metafun
Date: Tue, 13 Mar 2012 15:45:53 +0100 [thread overview]
Message-ID: <4F5F5DA1.1050202@uni-bonn.de> (raw)
Hi all,
scenario: for a presentation, I want the background to be a random
picture, taken from a directory "backgroundpics." The pictures are
numbered consecutively as 1.jpg through 22.jpg. For some complex
reasons, it would be easier for me to include these pictures via metafun
(I want to add other graphical elements on top). So my question is, how
can I pick a random picture? Given the code
StartPage ;
draw externalfigure "backgoundpics/1" xscaled PaperWidth yscaled
PaperHeight ;
StopPage ;
how can I obtain a random number and make metapost pick the
corresponding picture? Sorry, difficult to make a minimal example here...
Thomas
