Details:
Here is a simple script that illustrates the problem.
close all
graphics_toolkit qt
plot (1:10, 'o-')
print hardcopy_on.svg
set (gcf, "inverthardcopy", "off")
print hardcopy_off.svg
I thought the figure property "inverthardcopy" might have something to do with
it, but it doesn't.
If you open the resulting svg file in a viewer such as Inkscape you will find
that there are two planes which cover the entire area of the figure. One of
these is white and one of these is black.
Besides the unnecessary duplication, the issue is that exporting to rasterized
anti-aliased formats can result in a small grey line around the border of the
figure as the anti-alias mechanism combines the two planes.
This is a regression from 4.0.3 when there was only one plane. I haven't
tested with 4.2.1 yet.
