2D Orthographic camera movement clamp in any orthographic size
Hello guys.I have a problem, which i currently can't figure out how to solve. I am trying to calculate a clamp value for world coordinates which have to respect any camera orthographic size.I bought an image file just to illustrate it better. 
Picture 1 and 2 are my current results which i get from the camera extents.Picture 3 and 4 illustrates the problem i need to solve.So for example if i lower a little bit the camera orthographic size, if the clamp values stay the same, there is a space between the camera view and the world map which can't be covered by the clamped values in this current condition.So is there any way i can calculate the clamped positions in every camera orthographic size?Can somebody help me out?
Orthographic.size is 1/2 of the world height seen by the camera. So in order to generate the values:
var minY = Camera.main.transform.position.y - Camera.main.orthographicSize;
var maxY = Camera.main.transform.position.y + Camera.main.orthographicSize;
Ah yes i was not sure if this was the right answer, but now i see it is somehow contributing to me to get the final result. When i get the camera bounds like robertbu wrote i then get the $$anonymous$$imum and maximum positions of the map in world space and then apply the clamp. Thanks!
I guess reading back your question, I did not give you what you indicated in the first line. Here are two answers (one use OrthographicSize and one using viewport coordinates) for this problem:

I believe that both assume that the map is centered at the origin. It would take a bit more work if the map is not centered on the origin.
