Enum Constant Detail

COMPATIBLE

public static final BlendMode COMPATIBLE

No longer needed but still recognized; equivalent to the Normal blend mode.

NORMAL

public static final BlendMode NORMAL

Selects the source color, or the color in the graphics object, and ignores the backdrop.

MULTIPLY

public static final BlendMode MULTIPLY

Multiplies the source color and the backdrop color. This means that the color will always be at least as dark as the constituent colors. If either the source object or the backdrop is black, the color will be black.

SCREEN

public static final BlendMode SCREEN

Multiplies the complements of the source color and the backdrop, and then complements the result. The result is always as light as either of the constituent colors.

DIFFERENCE

public static final BlendMode DIFFERENCE

Subtracts the darker of the two constituent colors from the lighter color.

DARKEN

public static final BlendMode DARKEN

Selects the darker of the backdrop or source colors.

LIGHTEN

public static final BlendMode LIGHTEN

Selects the lighter of the backdrop or source colors.

COLOR_DODGE

public static final BlendMode COLOR_DODGE

Brighten the backdrop color to reflect the source color.

COLOR_BURN

public static final BlendMode COLOR_BURN

Darken the backdrop color to reflect the source color.

EXCLUSION

public static final BlendMode EXCLUSION

Similar to the Difference mode, but lower in contrast.

HARD_LIGHT

public static final BlendMode HARD_LIGHT

Multiplies or screens the colors, depending on the source color value.

OVERLAY

public static final BlendMode OVERLAY

Multiplies or screens the colors, depending on the backdrop color value. Source colors overlay the backdrop while preserving highlights and shadows. The backdrop color is mixed with the source color to reflect the lightness or darkness of the backdrop.

SOFT_LIGHT

public static final BlendMode SOFT_LIGHT

Darkens or lightens the colors, depending on the source color value.

LUMINOSITY

public static final BlendMode LUMINOSITY

Creates a color with the luminosity of the source color and the hue and saturation of the backdrop color.

HUE

public static final BlendMode HUE

Creates a color with the hue of the source color and the saturation and luminosity of the background color.

SATURATION

public static final BlendMode SATURATION

Creates a color with the saturation of the source color and the hue and luminosity of the backdrop color.

COLOR

public static final BlendMode COLOR

Creates a color with the hue and saturation of the source color and the luminosity of the backdrop color.

UNKNOWN

public static final BlendMode UNKNOWN

Method Detail

values

public static BlendMode[] 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 (BlendMode c : BlendMode.values())
    System.out.println(c);

Returns:

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

valueOf

public static BlendMode 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
