Hey someone said something nice about transforms!
Eric, I haven't had a chance to try this code out but I did read
through it and it looks very nice. A small comment: fig.dpi is
already a Value, so I don't think you want
+ elif self.units == 'inches':
+ dpi = ax.figure.dpi.get()
+ dx = T.Value(dpi)
because that is copy semantics and you probably want reference
semantics
+ elif self.units == 'inches':
+ dx = ax.figure.dpi
That way if someone changes the figure dpi. Or maybe I'm missing
something and you really want copy.
fig.dpi.set(72.)
all of your transforms are automagically updated.
Is there any reason not to commit this to svn? It seems to live in
parallel with the existing quiver, so shouldn't cause anyone any
grief.
