在写如下代码的时候，matplotlib模块引起了我的兴趣。
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import matplotlib as mpl
import matplotlib.cm
import matplotlib.colors
def color_image(image, num_classes=20):
norm = mpl.colors.Normalize(vmin=0., vmax=num_classes)
mycm = mpl.cm.get_cmap('coolwarm')
return mycm(norm(image))因为想进一步了解该模块的使用，我开始阅读matplotlib模块对应的实现源码。matplotlib模块实现源码的位置在 ./anaconda2/lib/python2.7/site-packages/matplotlib/cm.py 。

"""Return custom data dictionary of (r,g,b) conversion functions, which
can be used with :func:`register_cmap`, for the cubehelix color scheme.
Unlike most other color schemes cubehelix was designed by D.A. Green to
be monotonically increasing in terms of perceived brightness.
Also, when printed on a black and white postscript printer, the scheme
results in a greyscale with monotonically increasing brightness.
This color scheme is named cubehelix because the r,g,b values produced
can be visualised as a squashed helix around the diagonal in the
r,g,b color cube.
For a unit color cube (i.e. 3-D coordinates for r,g,b each in the
range 0 to 1) the color scheme starts at (r,g,b) = (0,0,0), i.e. black,
and finishes at (r,g,b) = (1,1,1), i.e. white. For some fraction *x*,
between 0 and 1, the color is the corresponding grey value at that
fraction along the black to white diagonal (x,x,x) plus a color
element. This color element is calculated in a plane of constant
perceived intensity and controlled by the following parameters.
Optional keyword arguments:
========= =======================================================
Keyword Description
========= =======================================================
gamma gamma factor to emphasise either low intensity values
(gamma < 1), or high intensity values (gamma > 1);
defaults to 1.0.
s the start color; defaults to 0.5 (i.e. purple).
r the number of r,g,b rotations in color that are made
from the start to the end of the color scheme; defaults
to -1.5 (i.e. -> B -> G -> R -> B).
h the hue parameter which controls how saturated the
colors are. If this parameter is zero then the color
scheme is purely a greyscale; defaults to 1.0.
