- (instancetype)initWithMaskImage:(LTRasterImage *)maskImage 
                            flags:(LTDigitalSubtractCommandFlags)flags 
             
public DigitalSubtractCommand( 
   RasterImage maskImage,  
   int flags 
) 
             
function DigitalSubtractCommand(  
   maskImage , 
   flags  
) 

Parameters

maskImage
RasterImage object that references the mask image. This image will not be affected.
