virtual L_INT LBitmap::SliceCallBack(Bitmap, lpSliceRect, nAngle)
Handles each slice segment found by the LBitmap::Slice function.
Optional parameter that points to the bitmap handle referencing the sliced bitmaps. It is the programmer's responsibility to free this bitmap (using LBitmapBase::Free, and GlobalFree(pBitmap)) when it is no longer needed. This parameter is updated only if SLC_CUTSLICES flag of the SLICEBITMAPOPTIONS structure is used, else it will be NULL.
Pointer to a RECT structure that contains the bounding rectangle of the extracted slice.
Deskew angle. The amount of rotation is expressed in hundredths of degrees. For example, 500 means 5 degrees clockwise.
Value | Meaning |
---|---|
>0 | Continue the process. |
-1 | Stop the process and return the specified error code. Refer to Return Codes. |
NOTE: the slice functionality is not currently supported in the C++ Class Library. However, this functionality can be implemented by calling the C API function directly. For a code sample that indicates how to call the C API function from your code, refer to LBitmap::Slice.
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.
Win32, x64.
For an example, refer to LBitmap::Slice.
