)

  
Public Function AddSegment( _ 
   ByVal image As RasterImage, _ 
   ByVal data As MrcSegmentData _ 
) As Integer

public: 
int AddSegment(  
   RasterImage^ image, 
   MrcSegmentData data 
)

Parameters

image
The image in which the segment will be created.

data
Information about the segment that will be added.

This method adds a new segment using the coordinates and the type specified in the data parameter.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Mrc; 
 
public void AddSegmentExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "PDFSegmentation.pdf")); 
 
   MrcSegmentData data = MrcSegmentData.Empty; 
   MrcSegmenter mrcSegmenter = new MrcSegmenter(image, RasterColor.FromKnownColor(RasterKnownColor.White), RasterColor.FromKnownColor(RasterKnownColor.Black)); 
   data.ImageSegment = new LeadRect(0, 0, 20, 60); 
 
   data.SegmentType = MrcSegmentType.Picture; 
   mrcSegmenter.AddSegment(image, data); 
}
