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.

fist file: sq-auto-crop.sh
#!/bin/bash
if [ $# -ne 2 ] ; then
echo "Usage: $0 infile outfile"
exit 1
fi
gimp -i -b "(sq-auto-crop \"$1\" \"$2\")" -b '(gimp-quit 0)'
#EOF
second file: sq-auto-crop.scm
;------------------------------------------------------------------------------
(define
(sq-auto-crop inFile outFile)
(let*
(
(im 0)
(dw 0)
)
; load the original
(set! im (car (gimp-file-load RUN-NONINTERACTIVE inFile inFile)))
(set! dw (car (gimp-image-get-active-layer im)))
; auto-crop
(plug-in-autocrop RUN-NONINTERACTIVE im dw)
; save the cropped image
(gimp-file-save RUN-NONINTERACTIVE im dw outFile outFile)
)
)
;EOF

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
