Oh yes, I mean, you can autotrim with imagemagick as well, for example by mogrify -path ./destination -format png -trim *.png
This is for a batch job in fact; for single images, gimp certainly comes in handy, particularly because you can select the background and make it transparent there. This is not batchable though I believe.
