Zooming chart in splash Screen

Hi Suresh,

There are two methods to zoom an image.

1. Set the background image of a panel and set the image layout. For example, we can drag and drop a panel onto the form. Set its BackgroundImage property to the image and set its BackgroundImageLayout property to Stretch.

2. Draw the image with a source rectangle and a destination rectangle as parameters. This is a code snippet:

    protected override void OnPaint(PaintEventArgs e)
    {
        base.OnPaint(e);
        //Get image.
        Image img = Properties.Resources.untitled;
        //Zoom factor.
        float zoomFactor = 4.0f;
        //The rect of the image which would be draw.
        Rectangle imgRect = new Rectangle();
        imgRect.Location = Point.Empty;
        imgRect.Size = img.Size;
        //The rect of the form where we would draw the image.
        Rectangle drawRect = new Rectangle();
        //This is the location where you want to draw the image.
        drawRect.Location = new Point(5,5);
        //Change the size according to the zoom factor.
        drawRect.Size = new Size((int)(img.Size.Width * zoomFactor), (int)(img.Size.Height * zoomFactor));
        //Draw the image.
        e.Graphics.DrawImage(img, drawRect, imgRect, GraphicsUnit.Pixel);
    }
