fun createFromCharacteristics(

    cropRectTop: Float = TransformationInfo.CROP_NONE,
    cropRectRight: Float = TransformationInfo.CROP_NONE,
    cropRectBottom: Float = TransformationInfo.CROP_NONE
): TransformationInfo

Creates TransformationInfo from the provided CameraCharacteristics and crop rect.

When using a viewfinder with {@docRoot]media/camera/camera2, this will generate the appropriate TransformationInfo to display the camera frames upright.

The crop rect will specify a region of interest (ROI) within the original buffer to treat as the buffer dimensions. When displaying the ROI in a viewfinder, depending on the scale mode, the crop rect bounding box should line up with the edges of the viewfinder, but pixels outside the bounding box will not necessarily be hidden if they still land within the bounds of the viewfinder.

fun createFromCharacteristics(

    cropRectTop: Float = TransformationInfo.CROP_NONE,
    cropRectRight: Float = TransformationInfo.CROP_NONE,
    cropRectBottom: Float = TransformationInfo.CROP_NONE
): TransformationInfo

Creates TransformationInfo from the provided CameraCharacteristics, crop rect, and mirror mode.

When using a viewfinder with {@docRoot]media/camera/camera2, this will generate the appropriate TransformationInfo to display the camera frames upright.

The crop rect will specify a region of interest (ROI) within the original buffer to treat as the buffer dimensions. When displaying the ROI in a viewfinder, depending on the scale mode, the crop rect bounding box should line up with the edges of the viewfinder, but pixels outside the bounding box will not necessarily be hidden if they still land within the bounds of the viewfinder.

The mirror mode is one of OutputConfiguration.MIRROR_MODE_AUTO, OutputConfiguration.MIRROR_MODE_NONE, OutputConfiguration.MIRROR_MODE_H, or OutputConfiguration.MIRROR_MODE_NONE, and should match what was set on OutputConfiguration.setMirrorMode. Note that before API level 33, the default behavior was equivalent to OutputConfiguration.MIRROR_MODE_AUTO.
