The problem with pcolor is that it draws all the pixels as polygons,
which is very inefficient in terms of file size. For example,
import matplotlib
matplotlib.use('PS')
from matplotlib.pyplot import *
import numpy as np
image = np.random.random((100,100))
fig = figure(figsize=(4,4))
ax = fig.add_subplot(111)
ax.pcolor(image)
fig.savefig('plot.ps')
produces a 2Mb+ file.
Thanks,
