Anyone know how to zoom in a picture box

[codeguy03]

I have an image and I can draw a rectangle on the image. However I don't have a clue as to zoom the image in on the rectangle that I have drawn. If the rectangle is drawn I want the picture to zoom in on that area on the mouseup event How can I do this?

You have to write the code for this:

public Image PictureBoxZoom(Image img, Size size)
{
    Bitmap bm = new Bitmap(img, Convert.ToInt32(img.Width * size.Width), Convert.ToInt32(img.Height * size.Height));
    Graphics grap = Graphics.FromImage(bm);
    grap.InterpolationMode = InterpolationMode.HighQualityBicubic; 
    return bm;
}

Search for it in CodeGuru itself . I have not tested the code above, so please refer to that article. Zom is not available as part of the framework as I know it, so you'll have to write on if you need it.
