EnumerateSegments Method

Summary
Enumerates the segments.
Syntax
C#
C++/CLI
Python
public int EnumerateSegments( 
   MrcEnumerateSegmentsInfo callback 
) 
public: 
int EnumerateSegments(  
   MrcEnumerateSegmentsInfo^ callback 
)  
def EnumerateSegments(self,callback): 

Parameters

callback
Callback method that will be called to enumerate the segments.

Remarks

This method enumerates all the segments using the MrcSegmenter method. This method is valid with all of the segmentation processes. For more information, refer to Programming with LEADTOOLS MRC.

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; 
} 
 
public void MrcSegmenterExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "PDFSegmentation.pdf")); 
 
   MrcSegmentImageOptions segmentImageOptions = MrcSegmentImageOptions.Empty; 
   segmentImageOptions.CleanSize = 5; 
   segmentImageOptions.SegmentQuality = 50; 
   segmentImageOptions.ColorThreshold = 25; 
   segmentImageOptions.BackgroundThreshold = 10; 
   segmentImageOptions.CombineThreshold = 75; 
   segmentImageOptions.Flags = MrcSegmentImageFlags.FavorOneBit | MrcSegmentImageFlags.SegmentWithBackground; 
 
   MrcSegmenter segmenter = new MrcSegmenter(image, RasterColor.FromKnownColor(RasterKnownColor.White), RasterColor.FromKnownColor(RasterKnownColor.Black)); 
   segmenter.SegmentImage(image, segmentImageOptions); 
 
   MrcEnumerateSegmentsInfo callBack = new MrcEnumerateSegmentsInfo(MrcEnumerateSegmentInfoCallback); 
   segmenter.EnumerateSegments(callBack);
