Public methods

getSupportedColorSpaces

Added in 1.7.0-alpha03

public @NonNull Set<@NonNull String> getSupportedColorSpaces(int imageFormat)

Get the supported color spaces for a given image format.

Parameters
int imageFormat	The image format to query.

Returns
@NonNull Set<@NonNull String>	The set of supported CameraColorSpaces.

getSupportedColorSpacesForDynamicRange

Added in 1.7.0-alpha03

public @NonNull Set<@NonNull String> getSupportedColorSpacesForDynamicRange(
    int imageFormat,
    long dynamicRangeProfile
)

Get the supported color spaces for a given image format and dynamic range profile.

Parameters
int imageFormat	The image format to query.
long dynamicRangeProfile	The dynamic range profile to query.

Returns
@NonNull Set<@NonNull String>	The set of supported CameraColorSpaces.

getSupportedDynamicRangeProfiles

Added in 1.7.0-alpha03

public @NonNull Set<@NonNull Long> getSupportedDynamicRangeProfiles(
    @NonNull String cameraColorSpace,
    int imageFormat
)

Get the supported dynamic range profiles for a given color space and image format.

Parameters
@NonNull String cameraColorSpace	The CameraColorSpace to query.
int imageFormat	The image format to query.

Returns
@NonNull Set<@NonNull Long>	A set of framework dynamic range profiles (e.g., android.hardware.camera2.params.DynamicRangeProfiles.HDR10)

getSupportedImageFormatsForColorSpace

Added in 1.7.0-alpha03

public @NonNull Set<@NonNull Integer> getSupportedImageFormatsForColorSpace(@NonNull String cameraColorSpace)

Get the supported image formats for a given color space.

Parameters
@NonNull String cameraColorSpace	The CameraColorSpace to query.

Returns
@NonNull Set<@NonNull Integer>	The set of supported image formats.

unwrapAs

Added in 1.7.0-alpha03

public T <T extends Object> unwrapAs(@NonNull Class<@NonNull T> type)

Attempts to unwrap this object into the specified underlying type.

Callers should use this method to retrieve the wrapped platform object.

Implementation Notes

• If the requested type is not supported by this wrapper, this method must return null.

• Implementations designed for testing (e.g., fakes, mocks, or no-op wrappers) should return null to signal that no real underlying object is available.

Parameters
<T extends Object>	The expected type of the underlying object.
@NonNull Class<@NonNull T> type	The Class representing the expected type of the underlying object.

Returns
T	The underlying object cast to T, or null if the object cannot be unwrapped into the requested type.
