Hi! I'm trying to display a 10800 x 8100 pixel image w/ imshow using the
following code (adapted from a response to a previous post of mine):
from matplotlib.backends.backend_agg import FigureCanvasAgg as FigureCanvas
from matplotlib.figure import Figure
fig = Figure(figsize=(36,27),
Oh, forgot to mention: same code works fine on a smaller (fewer pixels) image.

Ah, Ich verstehe now. I'll try RGBA-ing it; in the meantime, let me know if
the colormapping conversion gets changed to 32 bit. Thanks again!
