Can you please tell me how to implement this function?

Answer 1

public static Bitmap RotateImage(Image image, PointF offset, float angle)
{
    if (image == null)
        throw new ArgumentNullException("image");
        
    //create a new empty bitmap to hold rotated image
    Bitmap rotatedBmp = new Bitmap(image.Width, image.Height);
    rotatedBmp.SetResolution(image.HorizontalResolution, image.VerticalResolution);
    
    //make a graphics object from the empty bitmap
    Graphics g = Graphics.FromImage(rotatedBmp);
    
    //Put the rotation point in the center of the image
    g.TranslateTransform(offset.X, offset.Y);
    
    //rotate the image
    g.RotateTransform(angle);
    
    //move the image back
    g.TranslateTransform(-offset.X, -offset.Y);
    
    //draw passed in image onto graphics object
    g.DrawImage(image, new PointF(0, 0));
    
    return rotatedBmp;
}
