CombineSegments Method
See Also  Example
Leadtools.Mrc Namespace > MrcSegmenter Class : CombineSegments Method




id1
ID of the first segment to be combined.
id2
ID of the second segment to be combined.
flags
Flag that indicates how segments will be combined. For the MrcCombineSegmentFlags.ForeSimilar value, the following types are considered similar and could therefore be combined: OneColor, Background, Text1BitBw, Text2BitBw, Text1BitColor, Text2BitColor, Grayscale2Bit. These types are considered similar and therefore could be combined: Grayscale2Bit, Grayscale8Bit. These types are considered similar and therefore could be combined: Grayscale8Bit, Picture. refer to MrcCombineSegmentFlags
factor
A percentage value that represents the acceptable difference between the two segments being combined. This is valid only when flags is set to TryFactor. Possible values are between 0 and 100. A value of 0 indicates that only segments that are an exact match can be combined. A value of 100 indicates that any two segments of the same type can be combined. Large values cause very different segments to be joined, which causes considerable quality loss.
Combines two segments.

   // Load an image 
   RasterCodecs.Startup(); 
   RasterCodecs codecs = new RasterCodecs();

   segmenter.CombineSegments(0, 1, MrcCombineSegmentFlags.CombineForce, 20); 
}

Remarks

This method is used to combine two specific segments from the segmentation handle. The two segments must be in the same row or column to be combined.

This method can be used when performing automatic or manual segmentation. For more information, refer to Programming with LEADTOOLS MRC.

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
