I know in other Engines it is possible to start the Applikation in every Resolution i want, and it is also possible to save to picture of the Camera in a Image format want.
Because i want to print some scrrenshots of my Application, is this also possible in Unity?
And if so, how do i change the resolution beside the settings at the Start window.
Or is it even possible to save a screenshot in another resolution as the Application runs?
If you have unity pro, you can alternatively use a RenderTexture at the size you want and use Texture2D.ReadPixels to get the image into a Texture2D, then EncodeToPNG to get the bytes from that - how you write that to disk is up to you (though probably System.IO.File.WriteAllBytes)
Taking a complete screenshot in 8192x8192 gives me a very strange camera few. Also the render-scene-with-multiple-screenshots way is very unhandy since you have to stick the seperate shots together.
