public BorderRemoveCommand( 
   BorderRemoveCommandFlags flags, 
   BorderRemoveBorderFlags border, 
   int percent, 
   int whiteNoiseLength, 
   int variance 
)

- (instancetype)initWithFlags:(LTBorderRemoveCommandFlags)flags border:(LTBorderRemoveBorderFlags)border percent:(NSInteger)percent whiteNoiseLength:(NSInteger)whiteNoiseLength variance:(NSInteger)variance NS_DESIGNATED_INITIALIZER;

public BorderRemoveCommand( 
   int flags,  
   int border,  
   int percent,  
   int whiteNoiseLength,  
   int variance 
)

public: 
BorderRemoveCommand(  
   BorderRemoveCommandFlags flags, 
   BorderRemoveBorderFlags border, 
   int percent, 
   int whiteNoiseLength, 
   int variance 
)

__init__(self,flags,border,percent,whiteNoiseLength,variance) # Overloaded constructor

Parameters

flags
Flag that determines the behavior of the border removal process.

border
Flag that indicates which border to remove.

percent
Percent of the image dimension in which the border will be found. For most images, use 20. For example, if an image is 200 pixels wide, Percent is set to 20 and Border is set to BorderRemoveBorderFlags.Left, then the left border will be found in the area between the left edge of the image and a line 40 pixels from the left edge. If the border is closer to the edge of the image, use a smaller value. If the border is farther from the edge, use a larger value.

whiteNoiseLength
Amount of white noise tolerated when determining the border. The units are in pixels. Values of 0 to 10 are sufficient for most images.

variance
Amount of variance tolerated in the border. If the border varies significantly in thickness, you should use a higher value for Variance. Range is 0 to 10.

Example

Run the BorderRemoveCommand on an image.
