DigitalSubtractCommand Constructor(RasterImage,DigitalSubtractCommandFlags)

Summary

Initializes a new DigitalSubtractCommand class object with explicit parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public DigitalSubtractCommand( 
   RasterImage maskImage, 
   DigitalSubtractCommandFlags flags 
)

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

public DigitalSubtractCommand( 
   RasterImage maskImage,  
   int flags 
)

public: 
DigitalSubtractCommand(  
   RasterImage^ maskImage, 
   DigitalSubtractCommandFlags flags 
)

__init__(self,maskImage,flags) # Overloaded constructor

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.
