所有已实现的接口:

Serializable, Comparable<MaterialDesc.MaterialAlphaMode>

封闭类:

MaterialDesc

public static enum MaterialDesc.MaterialAlphaMode
extends Enum<MaterialDesc.MaterialAlphaMode>

Describes available alpha rendering modes of materials. Alpha rendering refers to rendering transparent pixels of materials to achieve transparency effects.

枚举常量概要

枚举常量

枚举常量	说明
BLEND	Indicates the alpha blending mode that combines the source regions with target regions based on the alpha value.
MASK	Indicates that the transparency of the rendering effect is determined by the alpha value and the given alpha cutoff value.
OPAQUE	Indicates a completely opaque rendering effect.
UNKNOWN	Indicates an unknown alpha rendering mode.

方法概要

限定符和类型	方法	说明
static MaterialDesc.MaterialAlphaMode	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 MaterialDesc.MaterialAlphaMode[]	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 (MaterialDesc.MaterialAlphaMode c : MaterialDesc.MaterialAlphaMode.values()) System.out.println(c);

枚举常量详细资料

UNKNOWN

public static final MaterialDesc.MaterialAlphaMode UNKNOWN

Indicates an unknown alpha rendering mode.

OPAQUE

public static final MaterialDesc.MaterialAlphaMode OPAQUE

Indicates a completely opaque rendering effect. The alpha value in this rendering mode is ignored.

MASK

public static final MaterialDesc.MaterialAlphaMode MASK

Indicates that the transparency of the rendering effect is determined by the alpha value and the given alpha cutoff value.

BLEND

public static final MaterialDesc.MaterialAlphaMode BLEND

Indicates the alpha blending mode that combines the source regions with target regions based on the alpha value. To be specific, the rendering output is combined with the background using a normal painting operation, the Porter and Duff over operator.

方法详细资料

values

public static MaterialDesc.MaterialAlphaMode[] 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 (MaterialDesc.MaterialAlphaMode c : MaterialDesc.MaterialAlphaMode.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 MaterialDesc.MaterialAlphaMode 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
