SegmentCommand Constructor(int,SegmentCommandFlags)

Summary

Initializes a new SegmentCommand class object with explicit parameters.

Syntax
C#
VB
Java
Objective-C
C++
Public Function New( _ 
   ByVal threshold As Integer, _ 
   ByVal flags As SegmentCommandFlags _ 
) 
- (instancetype)initWithThreshold:(NSUInteger)threshold 
                            flags:(LTSegmentCommandFlags)flags 
public SegmentCommand( 
   int threshold,  
   int flags 
) 
public: 
SegmentCommand(  
   int threshold, 
   SegmentCommandFlags flags 
) 

Parameters

threshold
The tolerance value of each segment. Valid values for this parameter are: 0 to 255 for 1, 2, 3, 4, 5, 6, 7, 8, 24, and 32-bit images, 0 to 4095 for 12-bit images and 0 to 65535 for 16, 48, and 64-bit images.

flags
Flag that indicates the color space used in the segmentation. For a list of possible values, refer to SegmentCommandFlags.

Example

Run the SegmentCommand on an image.
