L_MrcCreateNewSegment

#include "ltsgm.h"

L_LTSGM_API L_INT L_MrcCreateNewSegment(hSegment, pBitmap, pSegment)

HSEGMENTATION hSegment;

segmentation handle

pBITMAPHANDLE pBitmap;

pointer to a bitmap handle

pSEGMENTDATA pSegment;

pointer to a structure

Manually adds a new segment and sets the segment information.

Parameter

Description

hSegment

An existing segmentation handle. This handle is obtained by calling the L_MrcStartBitmapSegmentation function.

pBitmap

Pointer to the bitmap in which the segment will be created.

pSegment

Pointer to the SEGMENTDATA structure that contains the segment information.

Returns

>= 0

Index of the newly added segment. The function was successful.

< 0

An error occurred. Refer to Return Codes.

Comments

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.
