public class ShrinkWrapCommand : RasterCommand 
@interface LTShrinkWrapCommand : LTRasterCommand 
public class ShrinkWrapCommand

class ShrinkWrapCommand(RasterCommand): 
Remarks

The result is applied to the image as a region. This function was designed specifically for CT/MRI images, to segment regions of cancer clusters.

  • Use MakeRegionEmpty to delete the resulting region.
  • The radius must not exceed the length of the image diagonal or the class will throw an Invalid Parameters exception and will not execute.
  • This command does not support 32-bit grayscale images.
  • This command supports signed/unsigned images.
