I am an Ubuntu 12.04.4 LTS 32-bit user and I would like to automate the process of opening several PNG images as layers then saving these layers as a single animated GIF file in the GUI of GIMP. My intention is to write a BASH script but I have no idea on how to do that. I would be indebted if someone can provide help or point me in the right direction.

    Is the GIMP part really necessary? This is exactly what ImageMagick is designed for -- http://www.imagemagick.org/Usage/anim_basics/ – ToxicFrog May 31 '14 at 15:26
  • *If* you want to do this with gimp, the best way to do it is probably with [script-fu](http://docs.gimp.org/2.8/ca/gimp-concepts-script-fu.html), which uses scheme, perl, python, or tcl. – goldilocks May 31 '14 at 20:25
  • @ToxicFrog Apologies for my late comment but GIMP is not compulsory. What do you suggest that I do? – Vesnog Jun 01 '14 at 10:45
  • @goldilocks Thanks, but I am not familiar with script-fu but I would take a look at that. – Vesnog Jun 01 '14 at 10:46
  • @Vesnog the same thing as the answer slm gave you :) ImageMagick is seriously amazing for command-line image processing. – ToxicFrog Jun 01 '14 at 12:51
  • @ToxicFrog Yeah that program is a lot easier to use. – Vesnog Jun 01 '14 at 15:35

With ImageMagick you can convert a stack of PNG files into an animated GIF quite easily.

$ convert -delay 60 -loop 0 *.png sample.gif

I've used this technique to create several animated GIFs on this very site, for example, What is difference between w and W in escape mode of vim?.

  • Well thanks for the answer, it seems easier than GIMP command line mode, I will give it a try. – Vesnog Jun 01 '14 at 10:47
