Pen::RotateTransform method (gdipluspen.h)

The Pen::RotateTransform method updates the world transformation matrix of this Pen object with the product of itself and a rotation matrix.

Syntax

Status RotateTransform(
  [in] REAL        angle,
  [in] MatrixOrder order
);

Parameters

[in] angle

Type: REAL

Real number that specifies the angle of rotation in degrees.

[in] order

Type: MatrixOrder

Optional. Element of the MatrixOrder enumeration that specifies the order of the multiplication. MatrixOrderPrepend specifies that the rotation matrix is on the left, and MatrixOrderAppend specifies that the rotation matrix is on the right. The default value is MatrixOrderPrepend.

Return value

Type: Status

If the method succeeds, it returns Ok, which is an element of the Status enumeration.

If the method fails, it returns one of the other elements of the Status enumeration.
