void evdb::ColorScale::MakeHSVScale ( int  n, double  h1, double  h2, double  vs1, double  vs2  )

private

Make a color scale of n colors ranging between two points in an HSV color space.

Choose points so that the value of the colors changes uniformly. This ensures good viewing event in black and white.

Parameters

n	- number of colors in the scale
h1	- first H value in color scale
h2	- second H value in color scale
vs1	- first V value in color scale
vs2	- second V value in color scale
