枚举 ImageFormat.ComponentType

java.lang.Object

java.lang.Enum<ImageFormat.ComponentType>

ohos.media.image.common.ImageFormat.ComponentType

所有已实现的接口:

Serializable, Comparable<ImageFormat.ComponentType>

封闭类:

ImageFormat

public static enum ImageFormat.ComponentType
extends Enum<ImageFormat.ComponentType>

Describes the component type of encoding formats.

This enum defines the meaning and form of the components, which represent the structure model of image data.

枚举常量概要

枚举常量

枚举常量	说明
H264	Indicates the H264 format, which has no component.
H265	Indicates the H265 format, which has no component.
JPEG	Indicates the JPEG format, which has no component.
RAW10	Indicates the RAW10 format, which has no component.
RAW16	Indicates the RAW16 format, which has no component.
YUV_U	Indicates the U component in the YUV format.
YUV_V	Indicates the V component in the YUV format.
YUV_Y	Indicates the Y component in the YUV format.

方法概要

限定符和类型	方法	说明
static ImageFormat.ComponentType	valueOf(int value)	Obtains a ComponentType enum name based on its enum value.
static ImageFormat.ComponentType	valueOf(String name)	返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)
static ImageFormat.ComponentType[]	values()	按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示: for (ImageFormat.ComponentType c : ImageFormat.ComponentType.values()) System.out.println(c);

方法详细资料

values

public static ImageFormat.ComponentType[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

for (ImageFormat.ComponentType c : ImageFormat.ComponentType.values())
    System.out.println(c);

返回:

按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

valueOf

public static ImageFormat.ComponentType valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值

valueOf

public static ImageFormat.ComponentType valueOf(int value)

Obtains a ComponentType enum name based on its enum value.

参数:

value - Indicates the enum value.

返回:

Returns the enum name if any; returns null otherwise.
