inkscape vs gimp

[Ben Pfaff]

I noticed that all of our icons were made in inkscape. It looks like
inkspace is about 5x faster at rendering them to pngs than gimp:

$ time inkscape -o sps2.png --export-overwrite --export-type=png -d 96
256x256/mimetypes/application-x-spss-sps.svg

I don't see any quality difference in the output.

I agree with the comment in Smake that ImageMagick does a bad job.

Maybe it doesn't matter much though.
