public class BinaryFilterCommand : RasterCommand

@interface LTBinaryFilterCommand : LTRasterCommand

public class BinaryFilterCommand 
    extends RasterCommand

public ref class BinaryFilterCommand : public RasterCommand

class BinaryFilterCommand(RasterCommand):

Remarks

This command supports 12-bit and 16-bit grayscale and 48 and 64-bit color images. Support for 12-bit and 16-bit grayscale and 48-bit and 64-bit color images is available only in the Document/Medical toolkits.
This command does not support 32-bit grayscale images.

Example

Runs the BinaryFilterCommand on an image to dilate black objects.

   // Prepare the command
