在寫如下程式碼的時候，matplotlib模組引起了我的興趣。

#!/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))
 

  因為想進一步瞭解該模組的使用，我開始閱讀matplotlib模組對應的實現原始碼。matplotlib模組實現原始碼的位置在 ./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.
