💭 How to translate preview point to screen point with resizeMode contain?

[tomerh2001]

Question

I am using resize mode contain, so black bars appear at the camera's start and end.

I want to find the (0, 0) point of the preview in screen coordinates, accounting for the black bars.

But everything I tried seems to return the incorrect position on the screen, so I'm either experiencing a missing ; moment or missing some of the correct information.

How are the black bars calculated? How can I find the X from above using the parameters available in react-native-vision-camera?

If anyone could provide a previewPointToScreenPoint function or a getBlackBarsHeight function, that'd be very appreciated.

What I tried

No response

VisionCamera Version

4.0.5
