  • Image cannot be seen, url broken probably ? It depends on how you save it. If you save it in JPG, then you cannot save it 1:1. There is always algorithm in the middle to set the "quality" of that image. –  Jul 08 '16 at 06:26
  • Where can I find this algorithm my image is retrieved from the database so it can be of any format , – Ashraf Senan Jul 08 '16 at 06:32

  • Just info : If you want the same quality like in DB, then read it as byte array and save it again as byte array, that will be 1:1 –  Jul 08 '16 at 06:53
  • Always make sure you have control over the file format by including the `ImageFormat` parameter! Relying on the save name is __not__ good enough!! – TaW Jul 08 '16 at 08:20
