This happens when I convert a GIF into a series of PNG files.
I convert a .gif animation to a series of .png using
convert ex.gif my_png_files_%d.png
I get a series of .png-figures but some of the figures seem to be slightly shifted to the side or up/down. Example: if the gif-animation was just a red circle centred in the middle of a square, then the series of the pngs would produce this circle but this circle would be slight shifted off center in some direction in some of the pngs.
Anyone know what the issue is here?
