This is NOT a bug. You do NOT want to remove the page information as this is essentual to correct working of Animated GIFs. See Animation Cropping, and Viewport Cropping... http://www.cit.gu.edu.au/~anthony/graphics/imagick6/animations/#crop To do it properly use... convert jumping_egg.gif -crop 146x167+20+25! cropped.gif This is a veiw port crop, and not only crops the images (frames) but adjusts the canvas and position of the cropped frames to fit into the 'viewport' area specified. In other words, doing this will preserve the relative locations of all frames relative to each other.
