[magick-users] Animated GIF stop/start question

[rhubarbpie at poetworld.net]

I've generated drawn images using PerlMagick and combined them into an 
animated looping GIF.  However, is there a way to generate the GIF with 
a stop/freeze/pause option(s)?  In explanation, the GIF shows a moving 
part and being able to stop and review an individual frame would be 
helpful.  This may be a standard feature of animated GIFs of which I'm 
unaware.

If the above isn't possible, is it possible to generate the GIF to 
advance manually?
