DigitalSubtractCommand Constructor(RasterImage,DigitalSubtractCommandFlags)

Summary

Initializes a new DigitalSubtractCommand class object with explicit parameters.

Syntax
C#
VB
Java
Objective-C
C++
Public Function New( _ 
   ByVal maskImage As RasterImage, _ 
   ByVal flags As DigitalSubtractCommandFlags _ 
) 
- (instancetype)initWithMaskImage:(LTRasterImage *)maskImage 
                            flags:(LTDigitalSubtractCommandFlags)flags 
public DigitalSubtractCommand( 
   RasterImage maskImage,  
   int 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.

Example

Run the DigitalSubtractCommand on an image.
