You can try creating a figure with the correct aspect ratio and then setting a
corresponding dpi when you save:
#---
import matplotlib.pyplot as plt
import numpy as np
plt.figure(figsize=(10.24, 7.72))
x = np.linspace(0,2*np.pi,200)
plt.plot(x, np.sin(x))
plt.savefig('test', dpi=100)
#---
I had mixed results with this: I would occasionally get figures that were one
pixel smaller than desired.
