GetWorldTransform function

The GetWorldTransform function retrieves the current world-space to page-space transformation.

Syntax


BOOL GetWorldTransform(
  _In_  HDC     hdc,
  _Out_ LPXFORM lpXform
);

Parameters

hdc [in]

A handle to the device context.

lpXform [out]

A pointer to an XFORM structure that receives the current world-space to page-space transformation.

Return value

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.)
