Add support for Inkscape SVGs #168
Description
Situation:
I have a maths paper. I run pdf2svg or dvisvgm. I modify the svg with inkscape just minimally (for example I change the grouping of elements). I try to load it with SVGMobject. This fails.
Cause of the Problem:
Manim does not expect g and defs tags to have an id.
They have no id on dvisvgm output, but they do when saving the same svg from Inkscape.
Solution in svg_mobject.py replace get_all_childNodes_have_id with
def get_all_childNodes_have_id(self, element):
all_childNodes_have_id = []
if not isinstance(element, minidom.Element):
return
if element.hasAttribute('id') and (
not element.tagName == "g"
and
not element.tagName == "defs"
):
return [element]
for e in element.childNodes:
all_childNodes_have_id.append(self.get_all_childNodes_have_id(e))
return self.flatten([e for e in all_childNodes_have_id if e])
