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. This function is available in the (Document/Medical) toolkits.

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.
