I have working gmap run-processing gifanim code (20+ frames). I've tried to annotate an image into the background using an annotate dataset with image function. Also I've tried using goptions iback=. Either way, my resulting .gif stops playback on the second frame. Why?
The "exact same code" is pages long and may require some censoring. Meanwhile, I mocked up simple nonsense example code. Sure enough, it works just fine and I proved that I can do what I want to do. Still, in a new SAS session the "exact same code" works or doesn't work based on only the addition of ANNO=MY_ANNO into the Choro statement options. Same goes for adding IBACK=MY_IMG into the Goptions statement.
I'll hunt gremlins with fresh eyes tomorrow, and either post my solution or my problem.
