This indexed color model should never be modified. To change the indexed color model you should
create a new style with a different indexed color model instance.public float getScaleFactor()
Example use-case:
Assume you want to visualize a density plot for a layer containing cities, each represented by a point. The density should be based on the population of the city: cities with a large population should have a larger contribution to the density plot compared to cities with a small population.
This can be done by associating a weight to each city, based on the population.
However, the weight should be a factor between 0 and 1.
We could for example use as weight: city population / max population in the dataset.
If you want to use a color model which maps population values onto colors (and not the weighted values), you
can use this method to rescale the weights back to populations.
In this example, the scale factor would be max population in the dataset.
