SOLVED - Force camera to fixed aspect ratio and screenshot

Dear All,

I would like to ask for your help. I want to force a camera in C# to have the exact aspect ratio of an A4 size paper (297/210) and take a screenshot accordingly.

So far the code is as follows:

 Camera y = SCamera.GetComponent("Camera") as Camera;
 y.enabled=true;
 y.aspect=297/210; //SET ASPECT RATIO TO A4 SIZE
 Application.CaptureScreenshot("Screenshot.png",4);

In spite I set the camera aspect ratio, the taken screenshot is free aspect just as set in the Game view.

In advance I am thanking you for any help or hints.
