Compose CameraXViewfinder aspect ratio

[Nathan AUDVARD]

Hi,

Is there an easy way to have a CameraXViewfinder that match (and fit) the surface requested ?

I tried to divide surface's width by height and using it as aspect ratio modifier, but it only works in landscape. Since CameraXViewfinder has a fillMaxSize, setting width modifier with IntrinsicSize doesn't work either.

Thanks.

Hi,

The resolution from the SurfaceRequest is a size expressed in the device' camera sensor coordinate system. You can register the TransformationInfoListener by SurfaceRequest#setTransformationInListener(), and get the rotation degrees info by TransformationInfo#getRotationDegrees() to know whether you should flip the width and height values to adjust your CameraXViewfinder to match the surface resolution.
