[C#] Bitmap 大小縮放

下午在做報表功能時，發現某一塊資訊顯示區域太大，一半就這麼消失了...

google了一下，找到了這篇[C#] 影像檔大小縮放，發現它完全達到跟我所需要的功能

所以拿了這兩個Function來用

程式碼:

 public static Bitmap Resize(Bitmap originImage, Double times)
        {
            int width = Convert.ToInt32(originImage.Width * times);
            int height = Convert.ToInt32(originImage.Height * times);

            return Process(originImage, originImage.Width, originImage.Height, width, height);
        }

        private static Bitmap Process(Bitmap originImage, int oriwidth, int oriheight, int width, int height)
        {
            Bitmap resizedbitmap = new Bitmap(width, height);
            Graphics g = Graphics.FromImage(resizedbitmap);
            g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.High;
            g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;
            g.Clear(Color.Transparent);
            g.DrawImage(originImage, new Rectangle(0, 0, width, height), new Rectangle(0, 0, oriwidth, oriheight), GraphicsUnit.Pixel);
            return resizedbitmap;
        }
