#include "ltwrappr.h"

virtual L_INT LBitmapBase::SliceCallBack(Bitmap, lpSliceRect, nAngle)

LBitmapBase Bitmap;

/* reference to the LBitmapBase object */

LPRECT lpSliceRect;

/* pointer to the bounding rectangle of the extracted slice */

L_INT nAngle;

/* deskew angle */

Handles each Slice segment found by the LBitmapBase::Slice function.

Parameter

Description

Bitmap

lpSliceRect

Pointer to a RECT structure that contains the bounding rectangle of the extracted slice.

nAngle

Deskew angle. The amount of rotation is expressed in hundredths of degrees. For example, 500 means 5 degrees clockwise.
