Property Value

Value that indicates whether to expand or compress the image, and by how much. If Stretch < 100 image will be expanded. If Stretch > 100 the image will be compressed. Use 100 to maintain the image's dimensions. The value of this property is internally divided by 100. This property only accepts positive values.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
 
public void TunnelCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Beauty16.jpg")); 
 
   // Prepare the command 
   TunnelCommand command = new TunnelCommand(); 
   command.CenterPoint = new LeadPoint(image.Width / 2, image.Height / 2); 
   command.ZValue = 0; 
   command.Distance = image.Height; 
   command.Radius = image.Width / 2; 
   command.Repeat = -1; 
   command.RotationOffset = 0; 
   command.Stretch = 25; 
   command.StartBright = 0; 
   command.EndBright = 100; 
   command.BrightLength = 20000; 
   command.BrightColor = new RasterColor(255, 255, 255); 
   command.FillColor = new RasterColor(0, 0, 0); 
   command.Flags = TunnelCommandFlags.WidthAxis | TunnelCommandFlags.Color; 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
}
