Detailed Description

The class visualizes a ColorVector together with a scale (axis) and a caption. ColorLegends are vertical or horizontal

Member Enumeration Documentation

enum SCALEPOSITION

Possible anchor points for caption and axis.

Enumerator
Top	scale on top
Bottom	scale on bottom
Left	scale left
Right	scale right

enum ORIENTATION

Orientation of the legend.

Enumerator
BottomTop	Positionate the legend vertically, the lowest color index is on the bottom.
LeftRight	Positionate the legend horizontally, the lowest color index is on left side.

Constructor & Destructor Documentation
