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.

C#
VB
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.SpecialEffects; 
using Leadtools.Drawing; 
 
public void GradientFillRectangle(Graphics g, Rectangle destRect) 
{ 
   SpecialEffectsProcessor processor = new SpecialEffectsProcessor(); 
 
   processor.GradientFillRectangle(g, destRect, SpecialEffectsGradientStyle.EllipseToC, Color.Red, Color.Blue, 12); 
}
