In fact, I would like something like datad for colormaps.
I use it like this:
def __init__(self, **traits):
HasTraits.__init__(self, **traits)
dict_colormaps = copy(datad)
self.cmap = get_cmap(self.default_colormap)
for cm in dict_colormaps.keys():
if (cm[-2:] == '_r'):
dict_colormaps.pop(cm)
Doing this, I can display in my traits app the list of colormaps.
I would like to have something similar for available interpolation
methods.
I guess that implies to remove intperd from the AxesImage class,
as datad does not belong to any class, IIUC.
Obviously, I can build this list myself, hard-coding it,
but I would prefer something "cleaner".
Cheers,
