IInkTransform::Rotate

4/8/2010

Changes the amount of rotation, measured in degrees, to change the rotation factor of the IInkTransform object. Optionally, also changes the center point of the rotation.

Syntax

HRESULT Rotate (
  [in] float Degrees,
  [in, optional, defaultvalue(0)] float x,
  [in, optional, defaultvalue(0)] float y
);

Parameters

  • Degrees
    The degrees by which to rotate clockwise. Without the optional x and y arguments, rotation takes place around the origin point, which by default is the upper left corner of the ink collection area to which the transform is applied.
  • x
    The x–coordinate of the point in ink space coordinates around which rotation occurs. This defaults to the origin (the upper left corener of the ink collection area).
  • y
    The y–coordinate of the point in ink space coordinates around which rotation occurs. This defaults to the origin (the upper left corener of the ink collection area).
