GetWorldTransform
The GetWorldTransform
function retrieves the current world-space to page-space transformation.
BOOL GetWorldTransform(
|
HDC hdc, |
// handle to the
device context |
|
LPXFORM lpXform |
// pointer to the
structure receiving transformation |
|
); |
|
Parameters
hdc
Identifies
the device context.
lpXform
Points to an XFORM structure that receives
the current world-space to page-space transformation.
Return Values
If the
function succeeds, the return value is nonzero.
If the
function fails, the return value is zero.
Remarks
The precision
of the transformation may be altered if an application calls the ModifyWorldTransform
function prior to calling GetWorldTransform. (This is because the
internal format for storing transformation values uses a higher precision than
a FLOAT value.)
