ResolutionInfo

public ResolutionInfo(
    @NonNull Size resolution,
    @NonNull Rect cropRect,
    int rotationDegrees
)

Creates a new instance of ResolutionInfo with the given parameters. This constructor is not normally needed outside of testing cases.

public @NonNull Rect getCropRect()

Returns the crop rectangle.

The crop rectangle specifies the region of valid pixels in the buffer, using coordinates from (0, 0) to the (width, height) of the resolution obtained by getResolution. The dimensions need to be flipped by the rotation degrees obtained via getRotationDegrees to match the target rotation setting.

If the use case is configured with a ViewPort, this value is calculated based on the configuration of ViewPort; if not, it returns the full rect of the buffer which the dimensions will be the same as the value obtained from getResolution.

public @NonNull Size getResolution()

Returns the output resolution used for the use case.

The resolution will be expressed in the coordinates of the camera sensor. The dimensions need to be flipped by the rotation degrees obtained via getRotationDegrees to match the target rotation setting.

public int getRotationDegrees()

Returns the rotation degrees needed to transform the output resolution to the target rotation.

This is a clockwise rotation in degrees that needs to be applied to the output buffer so the image appears upright at the target rotation setting. The rotation will be determined by the camera sensor orientation value and target rotation setting.
