)

'Declaration
 
Public Sub CombineSegments( _
   ByVal id1 As Integer, _
   ByVal id2 As Integer, _
   ByVal flags As MrcCombineSegmentFlags, _
   ByVal factor As Integer _

   int factor
)

 function Leadtools.Mrc.MrcSegmenter.CombineSegments( 
   id1 ,
   id2 ,
   flags ,
   factor 
)

public:
void CombineSegments( 
   int id1,
   int id2,
   MrcCombineSegmentFlags flags,
   int factor
)

Parameters

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.

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.
