StatisticsInformationCommand Constructor(RasterColorChannel,int,int)

Summary

Initializes a new StatisticsInformationCommand with explicit parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public StatisticsInformationCommand( 
   RasterColorChannel channel, 
   int start, 
   int end 
)

- (instancetype)initWithChannel:(LTRasterColorChannel)channel start:(NSInteger)start end:(NSInteger)end NS_DESIGNATED_INITIALIZER;

public StatisticsInformationCommand( 
   RasterColorChannel channel, 
   int start, 
   int end 
);

public: 
StatisticsInformationCommand(  
   RasterColorChannel channel, 
   int start, 
   int end 
)

__init__(self,channel,start,end) # Overloaded constructor

Parameters

channel
The channel for which to get the information. This value is ignored if the image is 12 or 16-bit grayscale.

start
Indicates the beginning color value of the range for the evaluation. This property only accepts positive values.

end
Indicates the ending color value of the range for the evaluation. This property only accepts positive values.

Example

Run the StatisticsInformationCommand on an image.

   // Prepare the command 
   StatisticsInformationCommand command = new StatisticsInformationCommand(RasterColorChannel.Master, 0, 255); 
   // Get statistical image information. 
   command.Run(image);
