Now we have a function which will rotate an image to an arbitrary angle, I'm adding my code now to the form_load event so that as soon as the form loads my code is executed.īitmap bitmap = (Bitmap)pictureBox1.Image G.InterpolationMode = InterpolationMode.HighQualityBilinear Path.AddRectangle( new RectangleF(0f, 0f, w, h)) īitmap newImg = new Bitmap(Convert.ToInt32(rct.Width), Convert.ToInt32(rct.Height)) Graphics g = Graphics.FromImage(tempImg) Public static Bitmap RotateImg(Bitmap bmp, float angle) We will make a function RotateImg with two arguments one is the Bitmap Image and the other is the float angle. Now back to our code, add the namespaces to use as: The preceding code will rotate the image in a pictureBox1 by an angle of 180 degrees. The parameter of RotateFlip is, which specifies the type of rotation and flip to apply to the image.Į.g.

Now comes the real part, using Image.RotateFlip we can rotate the image by standard angles (90, 180 or 270 degrees) or flip the image horizontally or vertically. The following is the step-by-step process of how to use builtin functions for rotating and flipping an image.Ĭreate a blank Windows Forms application, as in:Īdd a pictureBox from the toolbox and add a source image to it. One of my friends asked me how to rotate an image to a particular angle, so I just thought of writing an article about it.
