Show in webframe

#include "ltwrappr.h"

virtual L_INT LBitmapRgn::Offset(nRowOffset, nColOffset)

L_INT nRowOffset;	/* number of rows to move the region */
L_INT nColOffset;	/* number of columns to move the region */

Moves the associated class object's bitmap region by the specified number of rows and columns. The move does not affect the pixels in the region.

Parameter	Description
nRowOffset	The number of rows to move the region.
nColOffset	The number of columns to move the region.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.
