OffsetViewportOrgEx

The OffsetViewportOrgEx function modifies the viewport origin for a device context using the specified horizontal and vertical offsets.

BOOL OffsetViewportOrgEx(

HDC hdc,	// handle to device context
int nXOffset,	// horizontal offset
int nYOffset,	// vertical offset
LPPOINT lpPoint	// pointer to structure receiving original origin
);

Parameters

hdc

Identifies the device context.

nXOffset

Specifies the horizontal offset, in device units.

nYOffset

Specifies the vertical offset, in device units.

lpPoint

Points to a POINT structure. The previous viewport origin, in device units, is placed in this structure. If lpPoint is NULL, the previous viewport origin is not returned.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero.

Remarks

The new origin is the sum of the current origin and the horizontal and vertical offsets.
