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.
