I recently commited a fix, but now it appears there might be a new problem with this filter. It doesn't look directly related to the fix to this particular bug, but it perhaps it has something to do with one my other fixes (or someone else's). Unfortunately I cannot reproduce the problem, so I'd like to know who CAN reproduce it (and how).
I just checked with clean Inkscape 0.47+devel r9357 and I can reproduce the black dots around the objects. To reproduce, just
- create an empty drawing
- Import png image with semitransparent pixels (one created in GIMP or
mentioned 455302-ink_bleed_error-test.png)
Now I see it as well, thanks, I'll have a go at fixing it.
You should now see this rendering problem.
Anyway, it does not seem to be related to filters, but how (bitmap) images are displayed (test svg with filters applied works fine)
It seems it is related to image pixels that have nearly zero alpha (visible if you create transparent bitmap with a large fuzzy circle in GIMP, the black dots are rendered around the circle in Inkscape).
Indeed, I think I know where to look (I recently fixed a different bug related to this, probably something went wrong there).
