I just ran the rendering tests again, and compared to last week there were suddenly 16(!) new results. I've had a quick look at some of them and they all seem to be regressions related to filter rendering (affecting quite a lot of different filters). Could anyone who has touched the general filtering code in the last week please recheck their work? (I'm currently swamped with work, so I have no time to go after this myself.)
I've worked on the filtering code lately. Still, I'm unable to see any new problems in image export. Could you post some example images of these regressions?
And while I'm at it, let's describe what I've done there: In Inkscape preferences, there is now "Filter Quality" setting. It controls the rendering resolution and resampling settings in filters. As was with the old Blur quality setting, this also affects only the display, export will always use the highest quality.
Highest quality uses full resolution and bicubic resampling while rotating images High quality uses full resolution, but nearest neighbour resampling while rotating Normal quality and below uses limited resolution and nearest neighbour resampling while rotating
There are some problems when editing images at lower resolution. Transparent areas and odd lines are common. (but only in editing mode, export still should be as good as it has been)
