This is not batchable though I believe.
gimp is batchable, just a bit more involved than imagemagick. use the
procedure browser to find the procedure call signatures.

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.

Hi,
ParaView doesn't currently do this (unless its implemented in the
development version which I haven't used in a while).
A quick and dirty approach is with the ImageMagick suite. Another option is
the GIMP scriptfu. In either case one can apply the desired operations to an
image or a series of images generated in PV from the command line. I'm
partial to the GIMP because it offers so much more functionality than
ImageMagick. I am including a scriptfu I wrote to autocrop images from PV.
It's in 2 parts, a bash script that hides some of the nastyness of invoking
a scriptfu from the command line, and a scm scriptfu. Place the scm scriptfu
in ~/gimp-X.X/scripts . X.X is the GIMP version number on your system. That
should get you started.

Hi all,
for Paraview's "Save Screenshot" or "Save Animation", is it possible
to trim the resulting image to to get rid of the unnecessary
background, and even more so, to treat the background color as
"transparent" (e.g. when exporting to PNG)?
Cheers,
Nico
