Enum Class VideoColorRange

java.lang.Object

java.lang.Enum<VideoColorRange>

org.freedesktop.gstreamer.video.VideoColorRange

All Implemented Interfaces:

Serializable, Comparable<VideoColorRange>, Constable, Enumeration

@Generated("org.javagi.JavaGI")
public enum VideoColorRange
extends Enum<VideoColorRange>
implements Enumeration

Possible color range values. These constants are defined for 8 bit color values and can be scaled for other bit depths.

Enum Constants

Enum Constant	Description
_0_255	[0..255] for 8 bit components
_16_235	[16..235] for 8 bit components.
UNKNOWN	unknown range

Method Summary

Modifier and Type	Method	Description
static @Nullable Type	getType()	Get the GType of the VideoColorRange class.
int	getValue()	Get the numeric value of this enum
static VideoColorRange	of(int value)	Create a new VideoColorRange for the provided value
static VideoColorRange	of(MemorySegment address)	Create a new VideoColorRange for the value in the provided memory address.
void	offsets(VideoFormatInfo info, @Nullable Out<int[]> offset, @Nullable Out<int[]> scale)	Compute the offset and scale values for each component of info. For each component, (c invalid reference i - offset invalid reference i ) / scale invalid reference i will scale the component c invalid reference i to the range [0.0 .. 1.0].
static VideoColorRange	valueOf(String name)	Returns the enum constant of this class with the specified name.
static VideoColorRange[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

UNKNOWN

public static final VideoColorRange UNKNOWN

unknown range

_0_255

public static final VideoColorRange _0_255

[0..255] for 8 bit components

_16_235

public static final VideoColorRange _16_235

[16..235] for 8 bit components. Chroma has [16..240] range.

Method Details

values

public static VideoColorRange[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static VideoColorRange valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

of

public static VideoColorRange of(int value)

Create a new VideoColorRange for the provided value

Parameters:

value - the enum value

Returns:

the enum for the provided value

getValue

public int getValue()

Get the numeric value of this enum

Specified by:

getValue in interface Enumeration

Returns:

the enum value

of

public static VideoColorRange of(MemorySegment address)

Create a new VideoColorRange for the value in the provided memory address.

Parameters:

address - the memory address holding a enum value

Returns:

the enum for the value in the provided memory address

getType

public static @Nullable Type getType()

Get the GType of the VideoColorRange class.

Returns:

the GType

offsets

public void offsets(VideoFormatInfo info,
 @Nullable Out<int[]> offset,
 @Nullable Out<int[]> scale)

Compute the offset and scale values for each component of info. For each component, (c

invalid reference

i

- offset

invalid reference

i

) / scale

invalid reference

i

will scale the component c

invalid reference

i

to the

range [0.0 .. 1.0].

The reverse operation (c

invalid reference

i

* scale

invalid reference

i

) + offset

invalid reference

i

can be used to convert

the component values in range [0.0 .. 1.0] back to their representation in info and range.

Parameters:

info - a GstVideoFormatInfo

offset - output offsets

scale - output scale
