OffsetViewportOrgEx

BOOL OffsetViewportOrgEx(hdc, nXOffset, nYOffset, lpPoint)
HDC hdc;	/* handle of device context	*/
int nXOffset;	/* horizontal offset	*/
int nYOffset;	/* vertical offset	*/
LPPOINT lpPoint;	/* address of structure receiving the original origin	*/

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

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 in not returned. The POINT structure has the following format:

typedef struct tagPOINT { /* pt */

LONG x;

LONG y;

} POINT;

Return Value

The return value is TRUE if the function is successful. Otherwise, it is FALSE.

Comments

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