Detailed Description

Class for drawing a custom color scale.

The color scale consists of rectangular color bar (composed of fixed number of color intervals), optional labels, and title. The labels can be positioned either at the boundaries of the intervals, or at the middle of each interval. Colors and labels can be either defined automatically or set by the user. Automatic labels are calculated from numerical limits of the scale, its type (logarithmic or plain), and formatted by specified format string.
