You can turn off the rendering of the normal axes and axis, and clip
your data to an arbitrary patch or path; eg
"""
Clipping to arbitrary patches and paths
"""
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.path as path
import matplotlib.patches as patches
fig = plt.figure()
ax = fig.add_subplot(111, frameon=False, xticks=[], yticks=[])
im = ax.imshow(np.random.rand(10,10))
patch = patches.Circle((300,300), radius=100)
im.set_clip_path(patch)
plt.show()
