Re: [Inkscape-devel] Bug in Blend Modes, Please Help
I wrote some lib2geom pretty printers to help debug this problem. They
are in lib2geom's new 'tools' directory. To use them, add the
following to .gdbinit:
python
import sys
sys.path.insert(0, '/path/to/checkout/of/lib2geom/tools')
from lib2geom_gdb import register_lib2geom_printers
register_lib2geom_printers()
end
Using them, I found that this bug is actually a manifestation of two problems:
1. After grouping, _filter_bbox on the DrawingGroup representing the
layer is empty. It seems that SPGroup does not update the filter bbox
when a child is removed / added.
2. _drawbox on the same group is totally wrong (it has 1x1 size).
Problem 2 might actually be related to the wrongness of the
_filter_bbox code I mentioned earlier.
