'Declaration
 
Public Class RegionHolesRemovalCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage
 
Dim instance As RegionHolesRemovalCommand

public sealed class RegionHolesRemovalCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.Effects.RegionHolesRemovalCommand()

public ref class RegionHolesRemovalCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

This command is designed to work on images that have a region. It removes the holes from the image's region. If this command is used with an image that does not have a region, the "Invalid Parameter" error is returned.
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 supports 32-bit grayscale images.
