Orthographic camera : How to get the Position/Width/height of a sprite portion that is filmed?

Unity Engine

Hi.
So I’ve got a Sprite let’s call it “A” that is filmed by an orthographic camera which I can zoom In / Out and Pan.

I want to add another sprite “B” on top of it, with a top-left corner at the same position than the top-left corner of the visible portion of “A” , and a bottom-right corner at the same bottom-right corner of the visible portion of “A”.
(so that it will fill the totality of the viewscreen of the camera too)

So I need the exact position of the FILMED top-left corner of A and its bottom-right corner.

But I can’t find out which camera function can give me that…
Any help would be much appreciated!

Here’s a little sketch of what I’m searching :

It is not based on the camera.

The sprite exists in world space. What you should do is:

  • To get the size of the sprite in world space: Sprite’s size in pixel * PixelsPerUnit
  • Depending on where the pivot is, displace the point by that much. (if center + 0.5*widthInWorldSpace to get x2).

If you position your sprite using these numbers they will appear at the border of A no matter what camera you use.
