[ubuntu-art] Inkscape export and resizing

[Thorsten Wilms]

Hi!

Some say that higher quality output can be obtained by exporting from
Inkscape with the desired size x a-power-of-2, e.g double, fourfold or
eightfold.

It seems that is the case, but not always.

I did an experiment with just black text on white:

The GIMP and gThumb examples are scaled down from an Inkscape export of
eightfold size, using Cubic interpolation in GIMP and "High-Quality" in
gThumb, which is likely to be cubic, too.

For the difference images, I used GIMP's Difference layer mode. The
gThumb/GIMP difference is not entirely black, there are pixels with a
minimal value, but visually, this difference is pretty much
non-existent.


I would like to see suggestion for how to get the worst case for
Inkscape, where this method could shine the most.
