LBitmapBase::SliceCallBack

#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	Optional parameter that points to the LBitmapBase object referencing the sliced bitmaps. This parameter is updated only if SLC_CUTSLICES flag of the SLICEBITMAPOPTIONS structure is used, else it will be NULL.
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.

Returns

> 0	Continue the process.
-1	Stop the process and return the specified error code. Refer to Return Codes.

Comments

The callback is called once for each slice that is detected. Return a positive number to continue the process. Return a negative number to abort.
