式門遁甲

 

   

byte[] imageData=(byte[])row["Image"];

 

//↑讀進來的圖片檔案就有一定的尺寸了，不過寬不是200

 

MemoryStream ms = new MemoryStream(imageData, 0, imageData.Length);

 

Image graph = Image.FromStream(ms);

                              

這個是寬度P_Width = 200;

 

 P_Height這個高度用等比例 =((P_Width) / (graph.Width)) * (graph.Height));
 

 

Bitmap imageOut = new Bitmap(graph,P_Width,P_Height);

 

imageOut.Save(放路徑接.jpg檔名);

 

 

graph.Dispose();

 

imageOut.Dispose();

 

ms.Close();
