Summary

Initializes a new ColorThresholdCommandComponent class with explicit parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public ColorThresholdCommandComponent( 
   int minimumRange, 
   int maximumRange, 
   ColorThresholdCommandFlags flags 
)

- (instancetype)initWithMinimumRange:(NSInteger)minimumRange maximumRange:(NSInteger)maximumRange flags:(LTColorThresholdCommandFlags)flags NS_DESIGNATED_INITIALIZER;

public ColorThresholdCommandComponent(int minimumRange,  
                                      int maximumRange,  
                                      int flags)

public: 
ColorThresholdCommandComponent(  
   int minimumRange, 
   int maximumRange, 
   ColorThresholdCommandFlags flags 
)

__init__(self,minimumRange,maximumRange,flags) # Overloaded constructor

Parameters

minimumRange
Value that represents the minimum boundary used to threshold a specific color.

maximumRange
Value that represents the maximum boundary used to threshold a specific color.

flags
Flags that represent the value that should be distributed to the thresholded component.

Example
