I am getting the following error when I test on svn HEAD
jo...@flag:misc> python rasterization_demo.py

Ndict += len(renderer.used_characters)
AttributeError: 'MixedModeRenderer' object has no attribute 'used_characters'
Also, a minor potential buglet. In the following,
+ if dsu[0][0] < rasterization_zorder:
+ renderer.start_rasterizing()
+ dsu_rasterized = [l for l in dsu if l[0] < rasterization_zorder]
+ dsu = [l for l in dsu if l[0] >= rasterization_zorder]
+ else:
+ dsu_rasterized = []
I think one could construct a sufficiently empty axes that len(dsu)==0
so I suggest
+ if len(dsu) and dsu[0][0] < rasterization_zorder:
It might also be worthwhile employing a consistent usage when wrapping
the draw methods. We have
+ @allow_rasterization
def draw(self, renderer, *args, **kwargs):
+ @martist.allow_rasterization
def draw(self, renderer):
and
+ @artist.allow_rasterization
def draw(self, renderer):
If we take the time upfront to be consistent, any search replace
things we need to do later will be easier.
Thanks,
