How to extract frames from a GIF file preserving frame dimensions

gif, imagemagick

Solution

Use the `-coalesce` option:

`convert -coalesce brocoli.gif out%05d.pgm`

Problem

I have the following GIF image file: I want to extract its frames (using PGM output format) using this imagemagick command: ``` convert brocoli.gif out%05d.pgm ``` But each frame has a different size. How can I extract its frames while preserving the original gif file size?
