Handles each Slice segment found by the L_SliceBitmap function.
Optional parameter that points to the bitmap handle referencing the sliced bitmaps. It is the programmer's responsibility to free this bitmap (using L_FreeBitmap(pBitmap), 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.
A void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the pUserData parameter of L_SliceBitmap)Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.
|>0||Continue the process.|
|-1||Stop the process and return the specified error code. Refer to Return Codes.|
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.
For an example, refer to L_SliceBitmap.
