Graphics::ResetTransform method (gdiplusgraphics.h)

Article
02/22/2024

The Graphics::ResetTransform method sets the world transformation matrix of this Graphics 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 Status enumeration.

Remarks

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

Examples

The following example sets the world transformation of a Graphics object to a 45-degree rotation and then draws a rectangle. The code calls the ResetTransform method of the Graphics object and then draws a second rectangle. No rotation transformation is applied to the second rectangle.

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

   // Rotate the transformation and draw a rectangle.
   graphics.RotateTransform(45.0f);
   Pen blackPen(Color(255, 0, 0, 0));
   graphics.DrawRectangle(&blackPen, 100, 0, 100, 50);

   // Reset the transformation to identity, and draw a second rectangle.
   graphics.ResetTransform();
   Pen redPen(Color(255, 255, 0, 0));
   graphics.DrawRectangle(&redPen, 110, 0, 100, 50);
}
