stripes in the colorbar

Hi,
I used the colorbar with the imshow for a while for a while, but now when I
produce a pdf of svg, light stripes appear in the colorbar. When I try to
modify the file with inkscape, I see that the stroke color is unset. Is this a
bug, a feature, or my backend that produces the file. And how can I get rid of
that?

Regards, Stefan

Hi,

the same happens with "regular" colorbars, too. Me, too, I didn't
always have this issue but I can't tell when exactly it was
introduced. Looks more like a bug than a feature to me---at least on
screen the result looks ugly.

Best regards,
Daniel

I wonder if this is related to recent reports about white-lines in pcolor output?

Does this happen irrespectively of the backend?

Whether stroke color is set or unset is neither a bug nor a feature, it is a compromise.

Try experimenting with the antialiasing setting.

There have always been problems along these lines, because no combination of edgewidth, stroking on or off, and antialiasing on or off works without artifacts on all backends and for all values of alpha.

I would be delighted if someone could figure out a nice, clean, universal solution for this problem.
