L_INT LSegment::MrcSegmentBitmap(pBitmap, pSegOption)
Automatically segments the specified bitmap, finding the best segment combination without specifying minimum segment dimensions.
Pointer to the bitmap object that references the bitmap to be segmented.
Pointer to the SEGMENTEXTOPTIONS structure that controls the automatic segmentation process. This cannot be NULL.
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
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.
