Méthodes publiques

Méthode Description
ColorBlend ( System colors, float positions ) : System

Initializes a new instance of the ColorBlend class.
GetColor ( float pos ) : Color

Gets the color from the scale at position 'pos'.

If the position is outside the scale [0..1] only the fractional part is used (in other words the scale restarts for each integer-part).

ThreeColors ( System fromColor, System middleColor, System toColor ) : ColorBlend

Creates a linear gradient scale from three colors
ToBrush ( Rectangle rectangle, float angle ) : LinearGradientBrush

Converts the color blend to a gradient brush
TwoColors ( System fromColor, System toColor ) : ColorBlend

Creates a linear gradient scale from two colors
