What is it ?

################

**colormap** package provides simple utilities to convert colors between

RGB, HEX, HLS, HUV and a class to easily build colormaps for matplotlib. All

matplotlib colormaps and some R colormaps are available altogether. The

plot_colormap method (see below) is handy to quickly pick up a colormaps and

the test_colormap is useful to see test a new colormap.

Installation

###################

::

    pip install colormap

Example

##########

* Create your own colormap from red to green colors with intermediate color as

  whitish (diverging map from red to green)::

      c = Colormap()

      mycmap = c.cmap( {'red':[1,1,0], 'green':[0,1,.39], 'blue':[0,1,0]})

      cmap = c.test_colormap(mycmap)

* Even simpler if the colormap is linear::

      c = Colormap()

      mycmap = c.cmap_linear('red', 'white', 'green(w3c)')

      cmap = c.test_colormap(mycmap)

* check out the available colormaps::

      c = Colormap()

      c.plot_colormap('diverging')
