Is it possible to determine the device orientation if the app is locked to portrait?

Also what about macOS and Windows? I guess there might be a windows tablet that can have orientation?

we are close, this code detects the orientation of the camera (w/ device rotation off too). It could but currently doesn't rotate the image deliver on MediaCatpure (sp). That could probably be added, but I don't yet have that solution. I would be OK if the CameraView code performed that operation. not sure everyone would want that TBD.

Hey Shaun, I think this proposal has value. The code is working on the branch I forked in my repo. I have modified to Sample App to show the orientation changes in one of the floating labels.

Having not submitted before,

• do I push a my branch here? Porobably I don't have rights.
• make a PR and submit? If so, how?

Any suggestions or help are apprciated and I'm happy to change things.

This commit you mention seems to be IOS/Mac specific bug #2312

This proposal offers a new feature. It works well and isn't a big change

For me the only question is whether to rotate the image on
void OnMediaCaptured(Stream imageData);

I could see value in doing that for the user or leaving up to the user to decide what they want.

@bijington any thought on my proposal. Since it's my first I'm curious how the process works?

[bijington]

Sorry I've been preoccupied. I'll try and read over it and get back to you soon
