Graphics.ScaleTransform Method (Single, Single, MatrixOrder)

Applies the specified scaling operation to the transformation matrix of this Graphics in the specified order.

Namespace:  System.Drawing
Assembly:  System.Drawing (in System.Drawing.dll)

member ScaleTransform : 
        sx:float32 * 
        sy:float32 * 
        order:MatrixOrder -> unit

Parameters

sx
Type: System.Single

Scale factor in the x direction.

sy
Type: System.Single

Scale factor in the y direction.

order
Type: System.Drawing.Drawing2D.MatrixOrder

Member of the MatrixOrder enumeration that specifies whether the scaling operation is prepended or appended to the transformation matrix.

The scaling operation consists of multiplying the transformation matrix by a diagonal matrix whose elements are (sx, sy, 1). This method prepends or appends the transformation matrix of the Graphics by the scaling matrix according to the order parameter.

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. The code performs the following actions:

  • Rotates the world transformation matrix of the Windows Form by 30 degrees.

  • Scales that matrix by a factor of 3 in the x direction and a factor of 1 in the y direction by appending the scaling transformation with the Append member.

  • Draws a rotated, scaled rectangle with a blue pen.

The result is a parallelogram.
