pyku.colormaps

Reference implementation of DWD color maps

pyku.colormaps.get_cmap(name, kind='original', nbins=None)

Get cmap

Parameters:

• name (str) – name of the colormap

• kind (str) – Defaults to linear. One of {original, linear, segmented}

• nbins (int) – Number of bins for segmented color maps

Returns:

The colormap.

Return type:

matplotlib.colors.Colormap

Example

In [1]: import pyku.colormaps as colormaps
   ...: cmap = colormaps.get_cmap('temp_ano')
   ...: 

pyku.colormaps.get_cmap_colors(name, kind='original', nbins=None, encoding='hex')

Get cmap colors

Parameters:

• name (str) – name of the colormap

• kind (str) – Defaults to linear. One of {original, segmented}

• nbins (int) – Number of bins for segmented color maps

• encoding (str) – Encoding. Default to ‘hex’. One of {‘hex’, ‘rgb’}

Returns:

If encoding is ‘rgb’, return a list of red, green and blue

tuples. If encoding is ‘rgb’, return a list of hex.

Return type:

List
