Note that in the last release of GIF Editor underlying work with GIF format was changed and use now qgiflib library. ImageMagick is not very good to work with GIF, as it needs to have all frames in memory, that with large GIFs makes GIF Editor unusable, whereas qgiflib stores actual frames as PNG files on disk, that allows to load really big GIFs.

So keep it in mind when you'll read this book.
