L_LTSGM_API L_INT L_MrcCreateNewSegment(hSegment, pBitmap, pSegment)
Manually adds a new segment and sets the segment information.
An existing segmentation handle. This handle is obtained by calling the L_MrcStartBitmapSegmentation function.
Pointer to 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. The function was successful. |
| < 0 | 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 L_MrcStartBitmapSegmentation function before using any of the segmentation functions. When the handle to the segmentation is no longer needed, free it by calling the L_MrcStopBitmapSegmentation function.
