Remarks
  • This command deinterlaces video source images by removing the black lines. It proceeds by merging lines in the image and/or blending them. Different options are available through the use of flags.
  • 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.

Example

Run the DeinterlaceCommand on an image.

   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "interlaced_footage.jpg")); 
 
   // Prepare the command 
   DeinterlaceCommand command = new DeinterlaceCommand(); 
   command.Flags = DeinterlaceCommandFlags.Smooth | DeinterlaceCommandFlags.Odd; 
   // Remove odd lines smoothly. 
   command.Run(image);
