)

'Declaration

Public Function New( _
   ByVal maskImage As RasterImage, _
   ByVal flags As DigitalSubtractCommandFlags _
)

'Usage

Dim maskImage As RasterImage
Dim flags As DigitalSubtractCommandFlags
 
Dim instance As New DigitalSubtractCommand(maskImage, flags)

public DigitalSubtractCommand( 
   RasterImage maskImage,
   DigitalSubtractCommandFlags flags
)

- (instancetype)initWithMaskImage:(LTRasterImage *)maskImage
                            flags:(LTDigitalSubtractCommandFlags)flags

public DigitalSubtractCommand(
   RasterImage maskImage, 
   int flags
)

   maskImage ,
   flags 
)

public:
DigitalSubtractCommand( 
   RasterImage^ maskImage,
   DigitalSubtractCommandFlags flags
)

Parameters

maskImage: RasterImage object that references the mask image. This image will not be affected.
flags: Flags that indicate the action to take after subtraction has occurred.

Run the DigitalSubtractCommand on an image.
