Leadtools.ImageProcessing.Core Namespace > DigitalSubtractCommand Class > DigitalSubtractCommand Constructor : DigitalSubtractCommand Constructor(RasterImage,DigitalSubtractCommandFlags)



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.
Initializes a new DigitalSubtractCommand class object with explicit parameters. Supported in Silverlight, Windows Phone 7

Syntax

Visual Basic (Declaration) 
Public Function New( _
   ByVal maskImage As RasterImage, _
   ByVal flags As DigitalSubtractCommandFlags _
)
Visual Basic (Usage)Copy Code
Dim maskImage As RasterImage
Dim flags As DigitalSubtractCommandFlags
 
Dim instance As New DigitalSubtractCommand(maskImage, flags)
C# 
public DigitalSubtractCommand( 
   RasterImage maskImage,
   DigitalSubtractCommandFlags flags
)
C++/CLI 
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.

Example

Run the DigitalSubtractCommand on an image.
