MrcSegmenter Constructor(RasterImage,RasterColor,RasterColor)

Summary
Initializes a new MrcSegmenter with explicit parameters.
Syntax
C#
C++/CLI
Python
public: 
MrcSegmenter(  
   RasterImage^ image, 
   RasterColor backColor, 
   RasterColor foreColor 
) 
__init__(self,image,backColor,foreColor) # Overloaded constructor 

Parameters

image
Image that will be segmented.

backColor
Default base background color for the MRC image.

foreColor
Default base foreground color for the MRC image.

Remarks

This constructor will Initializes the fields needed to the segmentation process.

Example
C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Mrc; 
 
private bool MrcEnumerateSegmentInfoCallback(MrcSegmenter segmentHandle, MrcSegmentData data, int iD) 
{ 
   if (iD == 0) 
   { 
      MessageBox.Show("Segment ID : " + iD.ToString()); 
      MessageBox.Show("Left : " + data.ImageSegment.Left.ToString() + 
         "\nTop : " + data.ImageSegment.Top.ToString() + 
         "\nRight : " + data.ImageSegment.Right.ToString() + 
         "\nBottom : " + data.ImageSegment.Bottom.ToString()); 
   } 
   return true;
