Summary

Initializes a new UnsharpMaskCommand class object with explicit parameters.

Syntax
C#
VB
Objective-C
C++
Java
Public Function New( _ 
   ByVal amount As Integer, _ 
   ByVal radius As Integer, _ 
   ByVal threshold As Integer, _ 
   ByVal colorType As UnsharpMaskCommandColorType _ 
) 
- (instancetype)initWithAmount:(NSInteger)amount 
                        radius:(NSInteger)radius 
                     threshold:(NSInteger)threshold 
                     colorType:(LTUnsharpMaskCommandColorType)colorType 
public UnsharpMaskCommand( 
   int amount,  
   int radius,  
   int threshold,  
   UnsharpMaskCommandColorType colorType 
) 
public: 
UnsharpMaskCommand(  
   int amount, 
   int radius, 
   int threshold, 
   UnsharpMaskCommandColorType colorType 
) 

Parameters

amount
Value that represents an adjustment factor. This is a percentage.

radius
Value that indicates the size of the neighborhood used for blurring each pixel of the image.

threshold
Value that indicates the threshold for modifying the original value of the pixel. If the difference in the original pixel value and the blurred pixel value is greater than the threshold value, the original pixel value will be modified.

colorType
Flag that indicates the color space in which to apply the mask.

Example

Run the UnsharpMaskCommand on an image.
