   codecs.ThrowExceptionsOnInvalidImages = True

   Dim leadImage As RasterImage = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "Master.jpg")

   ' Prepare the command
   Dim command As ShadowCommand = New ShadowCommand
   command.Angle = ShadowCommandAngle.SouthEast
   command.Threshold = 0
   command.Type = ShadowCommandType.GrayShadow
   ' Apply shadow effect to the image.
   command.Run(leadImage)
   codecs.Save(leadImage, LeadtoolsExamples.Common.ImagesPath.Path + "Result.jpg", RasterImageFormat.Jpeg, 24)

   RasterCodecs.Shutdown()
End Sub
C# Copy Code
public void ShadowCommandExample() 
{ 
   // Load an image 
   RasterCodecs.Startup(); 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(LeadtoolsExamples.Common.ImagesPath.Path + "Master.jpg"); 
 
   // Prepare the command 
   ShadowCommand command = new ShadowCommand();

   RasterCodecs.Shutdown(); 
}

Remarks

  • This command applies a convolution matrix upon each color component and then combines the results in order to add shadows.
  • This command supports 12- and 16-bit grayscale and 48- and 64-bit color images. Support for 12- and 16-bit grayscale and 48- and 64-bit color images is available only in the Document/Medical toolkits.
  • This command does not support signed data images.
  • This command does not support 32-bit grayscale images.
