I realize that this isn’t exactly a Rails question, but I
am planning to use the information for a Rails app :-).
I’m interested in stacking GIFs w/transparent backgrounds,
will (it says here let the user cause different parts
of a diagram to appear and disappear.
Problem is, I haven’t found a way to stack images so that
this works. I’m using an opaque white image as the bottom
image, then layering others (with transparent backgrounds)
on top. If I set the opacity to (say) 0.5, I see all of
the diagrams, with different amounts of haziness. Help?
