The OffsetClipRgn function moves the clipping region of a device context by the specified offsets.
int OffsetClipRgn(
| HDC hdc, | // handle to device context |
| int nXOffset, | // offset along x-axis |
| int nYOffset | // offset along y-axis |
| ); |
Parameters
hdc
Identifies the device context.
nXOffset
Specifies the number of logical units to move left or right.
nYOffset
Specifies the number of logical units to move up or down.
Return Values
If the function succeeds, the return value specifies the new region's complexity and can be any one of the following values:
| Value | Meaning |
| NULLREGION | Region is empty. |
| SIMPLEREGION | Region is a single rectangle. |
| COMPLEXREGION | Region is more than one rectangle. |
| ERROR | An error occurred. (The current clipping region is unaffected.) |
