Graphics::ScaleTransform method (gdiplusgraphics.h)

  • Article

The Graphics::ScaleTransform method updates this Graphics object's world transformation matrix with the product of itself and a scaling matrix.

Syntax

Status ScaleTransform(
  [in] REAL        sx,
  [in] REAL        sy,
  [in] MatrixOrder order
);

Parameters

[in] sx

Type: REAL

Real number that specifies the horizontal scaling factor in the scaling matrix.

[in] sy

Type: REAL

Real number that specifies the vertical scaling factor in the scaling matrix.

[in] order

Type: MatrixOrder

Optional. Element of the MatrixOrder enumeration that specifies the order of multiplication. MatrixOrderPrepend specifies that the scaling matrix is on the left, and MatrixOrderAppend specifies that the scaling 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.
