Although GraphicsMagick is a fork of ImageMagick, there are dissimilarities between the two, namely in the support of image stacking in ImageMagick, but not in GraphicsMagick. Taken from the ImageMagick documentation:
convert wand.gif \( wizard.gif -rotate 30 \) +append images.gif
In this example, the
rotate command is applied only to the
wizard.gif resource. My question is: Is there an equivalent to image stacking in GraphicsMagick?
