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. |
