Detailed Description

Base class for continuous color colormaps.

In contrast to discrete color colormaps, where the number of colors is limited, continuous color colormaps are able to generate colors for an arbitrary value between 0 and 1 using its getf() method. Hence they are able to generate very fine grained color gradients.

To be compatible with other discrete color colormaps, a continuous colormap can also be set to a certain size with a fixed number of colors using the constructor or the resize() method. The colors can then be accessed by an integer index using the get() method. However, the access to the continuous colors is always possible via the getf() method.
