gnome.utilities.colormaps¶
This module contains an assortment of colormap objects.
Each one has one method:
get_color(value_list,range=(0,255),out_type=’int’)
- value_list: is a list (or any sequence) of values that you want a color to
correspond to.
range: is the range of values that define the two ends of the colormap
- out_type: is the type that the RGB triple it output in. The two options are:
‘int’ : integers between 0 and 255 ‘float’: floats between 0 and 1
returned is a list of tuples, each one an RGB triple that corresponds to the values in value_list, with each value between 0 and 255.
Each one also has one attribute:
- map_list: is a 256 element list of RGB triple tuples,
Each R,G,B value is an integer from 0 to 255.
You can create a new one by calling the constructor:
colormap(map_list)
and passing in your own list of tuples (it must have 256 elements)
The following colormaps are included:
autumn, bone, cool, copper, hot, hsv, jet, pink, winter
