枚举 Image.ScaleMode

java.lang.Object

java.lang.Enum<Image.ScaleMode>

ohos.agp.components.Image.ScaleMode

所有已实现的接口:

Serializable, Comparable<Image.ScaleMode>

封闭类:

Image

public static enum Image.ScaleMode
extends Enum<Image.ScaleMode>

Indicates the scaling mode of images.

This enumeration scales the edges of an image to be the same as those of a component.

枚举常量概要

枚举常量

枚举常量	说明
CENTER	Displays the image in the center of a component, without any scale.
CLIP_CENTER	Scales the image to be of the same or a larger size than that of an Image item according to a ratio, and displays the image content in the center.
INSIDE	Scales the image to be of the same or a smaller size than that of an Image item according to a ratio, and displays the image content in the center.
STRETCH	Scales the image to be of the same size as that of an Image item, without any ratio.
ZOOM_CENTER	Scales the image to be of the same width as that of an Image item according to a ratio, and displays the image content in the center.
ZOOM_END	Displays the image in the lower right corner of an Image item.
ZOOM_START	Displays the image in the upper left corner of an Image item.

方法概要

限定符和类型	方法	说明
static Image.ScaleMode	getByInt(int enumInt)	Obtains the enumeration object based on the value.
protected int	getValue()	Get the value of this scaling type.
static Image.ScaleMode	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 Image.ScaleMode[]	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 (Image.ScaleMode c : Image.ScaleMode.values()) System.out.println(c);

方法详细资料

values

public static Image.ScaleMode[] 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 (Image.ScaleMode c : Image.ScaleMode.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 Image.ScaleMode valueOf(String name)

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

getValue

protected int getValue()

Get the value of this scaling type.

返回:

Return the value of this scaling type.

getByInt

public static Image.ScaleMode getByInt(int enumInt)

Obtains the enumeration object based on the value.

参数:

enumInt - Indicates the enumeration value.

返回:

Returns the enumeration object matching the value.
