Pen::ResetTransform method (gdipluspen.h)

Article
02/22/2024

The Pen::ResetTransform method sets the world transformation matrix of this Pen object to the identity matrix.

Syntax

Status ResetTransform();

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 Ok enumeration.

Remarks

The identity matrix represents a transformation that does nothing. If the world transformation matrix of a Pen object is the identity matrix, then no world transformation is applied to items drawn using that Pen object.

Examples

The following example creates a Pen object, sets a scaling matrix to the pen, and draws a rectangle. The code then resets the transformation of the pen and draws a second rectangle.

VOID Example_ResetTrans(HDC hdc)
{
   Graphics graphics(hdc);

   // Create a pen, and set its transformation.
   Pen pen(Color(255, 0, 0, 255), 2);
   pen.ScaleTransform(8, 4);

   // Draw a rectangle with the transformed pen.
   graphics.DrawRectangle(&pen, 50, 50, 150, 100);

   pen.ResetTransform();

   // Draw a rectangle with no pen transformation.
   graphics.DrawRectangle(&pen, 250, 50, 150, 100);
}
