Convert animated GIF to PNG stack

Convert animated GIF to PNG stack using ImageMagick by:

convert in.gif out_%04.png

where 04 is governed by the number of images in the GIF–04 accommodates up to 10000 images.

Notes

GIFs are not a great format for science image data, because the palette is compressed to 8-bit (256 colors). For plotting reduced data, GIFs can be fine.
