LSegment::MrcSegmentBitmap

#include "ltwrappr.h"

L_INT LSegment::MrcSegmentBitmap(pBitmap, pSegOption)

Automatically segments the specified bitmap, finding the best segment combination without specifying minimum segment dimensions.

Parameters

LBitmapBase * pBitmap

Pointer to the bitmap object that references the bitmap to be segmented.

pSEGMENTEXTOPTIONS pSegOption

Pointer to the SEGMENTEXTOPTIONS structure that controls the automatic segmentation process. This cannot be NULL.

Returns

Value Meaning
SUCCESS The function was successful.
< 1 An error occurred. Refer to Return Codes.

Comments

Call this function to segment the bitmap automatically. LEAD will process the bitmap and break it into appropriate picture, grayscale, text and background segments.

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.
