Examples
The following example is intended to be used in a Windows Forms environment. It demonstrates how to use the ColorBlend class in conjunction with the LinearGradientBrush class to draw an ellipse to screen that has its colors blended. The ellipse is green on the left, blends to yellow, then to blue, and finally to red on the right. This is accomplished through the settings in the myColors
and myPositions
arrays used in the Colors and Positions properties. Note that the InterpolationColors property of the LinearGradientBrush object named lgBrush2
must be made equal to the ColorBlend object myBlend
.

virtual void OnPaint( PaintEventArgs^ e ) override

//Draw ellipse using ColorBlend.
