Manually adds a new segment to a specific stripe and sets the segment information.


#include "ltwrappr.h"

L_INT LSegment::MrcCreateNewSegment(pBitmap, pSegment)


LBitmapBase * pBitmap

Pointer to an LBitmapBase object that references the bitmap in which the segment will be created.


Pointer to the SEGMENTDATA structure that contains the segment information.


Value Meaning
>= 0 Index of the newly added segment.
< 1 An error occurred. Refer to Return Codes.


Use this function to manually add a new segment using the coordinates and type specified in pSegment.

Call the LSegment::MrcStartBitmapSegmentation function before using any of the segmentation functions. When the LSegment class object is no longer needed, free it by calling the LSegment::MrcStopBitmapSegmentation function.

The following example illustrates the use of LSegment::MrcCreateNewSegment in performing manual segmentation.

L_INT LSegment__MrcCreateNewSegmentExample(LBitmapBase & Bitmap) 
   LSegment       Segment; 
   SEGMENTDATA    SegData; 
   L_INT          nRet; 
   // Initialize the segmentation process 
   nRet = Segment.MrcStartBitmapSegmentation(&Bitmap, 
                                      RGB(255, 255, 255),  
                                      RGB(0, 0, 0)); 
   if(nRet != SUCCESS) 
      return nRet; 
   SegData.uStructSize = sizeof(SEGMENTDATA); 
   SegData.rcBitmapSeg.left = 20; = 20; 
   SegData.rcBitmapSeg.right = 60; 
   SegData.rcBitmapSeg.bottom = 60; 
   SegData.uType = SEGTYPE_PICTURE; 
   // Add a segment to the stripe just set 
   nRet = Segment.MrcCreateNewSegment(&Bitmap, &SegData); 
   if(nRet < 1) 
      return nRet; 
   // Clean up 
   nRet = Segment.MrcStopBitmapSegmentation(); 
   if(nRet != SUCCESS) 
      return nRet; 
   return SUCCESS;
