Moves the region stored in the CRgn object by the specified offsets.
int OffsetRgn(
int x,
int y
);
int OffsetRgn(
POINT point
);
Parameters
x
Specifies the number of units to move left or right.y
Specifies the number of units to move up or down.point
The x-coordinate of point specifies the number of units to move left or right. The y-coordinate of point specifies the number of units to move up or down. The point parameter may be either a POINT structure or a CPoint object.
Return Value
The new region's type. It can be any one of the following values:
COMPLEXREGION Region has overlapping borders.
ERROR Region handle is not valid.
NULLREGION Region is empty.
SIMPLEREGION Region has no overlapping borders.
Remarks
The function moves the region x units along the x-axis and y units along the y-axis.
The coordinate values of a region must be less than or equal to 32,767 and greater than or equal to –32,768. The x and y parameters must be carefully chosen to prevent invalid region coordinates.
Example
See the example for CRgn::CreateEllipticRgn.
