All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<RenderState.BlendEquationAlpha>

Enclosing class:

RenderState

public static enum RenderState.BlendEquationAlpha
extends java.lang.Enum<RenderState.BlendEquationAlpha>

BlendEquationAlpha specifies the blending equation to combine pixels for the alpha component.

Enum Constant Summary

Enum Constants

Enum Constant and Description
Add Sets the blend equation so that the source and destination data are added.
InheritColor Sets the blend equation to be the same as the one defined by RenderState.blendEquation.
Max sSets the blend equation so that the result alpha is the maximum of the source alpha and destination alpha.
Min Sets the blend equation so that the result alpha is the minimum of the source alpha and destination alpha.
ReverseSubtract Same as Subtract, but the order is reversed (Dst - Src).
Subtract Sets the blend equation so that the source and destination data are subtracted (Src - Dest).

Method Summary

Enum Constant Detail

InheritColor

public static final RenderState.BlendEquationAlpha InheritColor

Sets the blend equation to be the same as the one defined by RenderState.blendEquation.

Add

public static final RenderState.BlendEquationAlpha Add

Sets the blend equation so that the source and destination data are added. (Default) Clamps to [0,1] Useful for things like antialiasing and transparency.

Subtract

public static final RenderState.BlendEquationAlpha Subtract

Sets the blend equation so that the source and destination data are subtracted (Src - Dest). Clamps to [0,1] Falls back to Add if supportsSubtract is false.

ReverseSubtract

public static final RenderState.BlendEquationAlpha ReverseSubtract

Same as Subtract, but the order is reversed (Dst - Src). Clamps to [0,1] Falls back to Add if supportsSubtract is false.

Min

public static final RenderState.BlendEquationAlpha Min

Sets the blend equation so that the result alpha is the minimum of the source alpha and destination alpha. This and Max are useful for applications that analyze image data (image thresholding against a constant color, for example). Falls back to Add if supportsMinMax is false.

Max

public static final RenderState.BlendEquationAlpha Max

sSets the blend equation so that the result alpha is the maximum of the source alpha and destination alpha. This and Min are useful for applications that analyze image data (image thresholding against a constant color, for example). Falls back to Add if supportsMinMax is false.

Method Detail

values

public static RenderState.BlendEquationAlpha[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (RenderState.BlendEquationAlpha c : RenderState.BlendEquationAlpha.values())
    System.out.println(c);

Returns:

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

valueOf

public static RenderState.BlendEquationAlpha valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
