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...
(Untested)
draw externalfigure ("backgroundpics/" & round(uniformdeviate(22)+1))
Aditya
