I need to have an image with the exact physical display size on every phone or tablet.
Do you have an example to do that?

Have a look at the excellent manual written by klaus and erel (5. Screen and sizes on p.71 of version 1.6 of the beginners manual)

I guess you will need to do some calculations and resizing based on these values.

The following code uses reflection to extract the exact horizontal and vertical dpi (dots per inch) values:
B4X:
Sub Activity_Create (FirstTime As Boolean)
   Dim r As Reflector
   r.Target = r.GetContext
   r.Target = r.RunMethod("getResources")
   r.Target = r.RunMethod("getDisplayMetrics")
   Log(r.GetField("xdpi"))
   Log(r.GetField("ydpi"))
End Sub

Thank you very much Erel, I solved the problem :)
