28DEFINE_STANDARD_HANDLE(AIS_ColorScale, AIS_InteractiveObject)
180f89a2 29//! Class for drawing a custom color scale.
30//!
31//! The color scale consists of rectangular color bar (composed of fixed
32//! number of color intervals), optional labels, and title.
33//! The labels can be positioned either at the boundaries of the intervals,
34//! or at the middle of each interval.
35//! Colors and labels can be either defined automatically or set by the user.
36//! Automatic labels are calculated from numerical limits of the scale,
37//! its type (logarithmic or plain), and formatted by specified format string.
