枚举常量概要

枚举常量

枚举常量	说明
CENTER	Indicates the center mode, in which the source rectangle is scaled using the original aspect ratio and placed in the center of the destination rectangle.
END	Indicates the bottom mode, in which the source rectangle is scaled using the original aspect ratio and placed in the lower right corner of the destination rectangle.
FILL	Indicates the filling mode, in which the source rectangle is stretched to exactly match the destination rectangle.
START	Indicates the top mode, in which the source rectangle is scaled using the original aspect ratio and placed in the upper left corner of the destination rectangle.

方法概要

限定符和类型	方法	说明
int	value()	Obtains the enumeration identifier of modes of scaling a source rectangle into a destination rectangle.
static Matrix.ScaleToFit	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 Matrix.ScaleToFit[]	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 (Matrix.ScaleToFit c : Matrix.ScaleToFit.values()) System.out.println(c);

FILL

public static final Matrix.ScaleToFit FILL

Indicates the filling mode, in which the source rectangle is stretched to exactly match the destination rectangle.

START

public static final Matrix.ScaleToFit START

Indicates the top mode, in which the source rectangle is scaled using the original aspect ratio and placed in the upper left corner of the destination rectangle.

CENTER

public static final Matrix.ScaleToFit CENTER

Indicates the center mode, in which the source rectangle is scaled using the original aspect ratio and placed in the center of the destination rectangle.

END

public static final Matrix.ScaleToFit END

方法详细资料

values

public static Matrix.ScaleToFit[] 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 (Matrix.ScaleToFit c : Matrix.ScaleToFit.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 Matrix.ScaleToFit 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

value

public int value()

Obtains the enumeration identifier of modes of scaling a source rectangle into a destination rectangle.

返回:

Returns the enumeration identifier of modes of scaling a source rectangle into a destination rectangle.
