推荐答案

使用以下代码尝试缩放功能:

Try the zoom functionality using the below code:

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;
}
