Rotating an image in C#

You can rotate an image 45 degrees by drawing the image to a graphics object that has been rotated and is mapped to a bitmap. Below is the code I would use: Image myImage = Bitmap.FromFile("mybitmap.bmp"); _myRotatedImage = new Bitmap(myImage.Width, myImage.Height); Graphics g = Graphics.FromImage(_myRotatedImage); g.RotateTransform(45); g.DrawImage(myImage, 10, 10); g.Dispose(); Invalidate(); In your paint event handler: e.Graphics.DrawImage(_myRotatedImage, 10, 10); You only need to make sure that the rotated bitmap you created can fit the rotated image.
