destRect
Rectangle to be used as the display destination rectangle.
gradientStyle
Gradient style. For possible values refer to SpecialEffectsGradientStyle.
startColor
Value that specifies the starting color.
endColor
Value that specifies the ending color.
steps

Example

This Example shows the minimum requirements for using the GradientFillRectangle(Graphics,Rectangle,SpecialEffectsGradientStyle,Color,Color,Int32) method to draw and fill a rectangle with a color gradient.

Visual BasicCopy Code
Public Sub GradientFillRectangle(ByVal g As Graphics, ByVal destRect As Rectangle)
   Dim processor As SpecialEffectsProcessor = New SpecialEffectsProcessor()
   processor.GradientFillRectangle(g, destRect, SpecialEffectsGradientStyle.EllipseToC, Color.Red, Color.Blue, 12)
End Sub
C#Copy Code
public void GradientFillRectangle(Graphics g, Rectangle destRect)
{
   SpecialEffectsProcessor processor = new SpecialEffectsProcessor();
   processor.GradientFillRectangle(g, destRect, SpecialEffectsGradientStyle.EllipseToC, Color.Red, Color.Blue, 12);
}
