Enum Constant Details

Normal

public static final Blending Normal

Selects the source color, ignoring the backdrop

Multiply

public static final Blending Multiply

Multiplies the backdrop and source color values

Screen

public static final Blending Screen

Multiplies the complements of the backdrop and source color values, then complements the result

Overlay

public static final Blending Overlay

Multiplies or screens the colors, depending on the backdrop color value. Source colors overlay the backdrop while preserving its highlights and shadows. The backdrop color is not replaced but is mixed with the source color to reflect the lightness or darkness of the backdrop

Darken

public static final Blending Darken

Selects the darker of the backdrop and source colors.

Lighten

public static final Blending Lighten

Selects the lighter of the backdrop and source colors.

ColorDodge

public static final Blending ColorDodge

Brightens the backdrop color to reflect the source color. Painting with black produces no changes.

ColorBurn

public static final Blending ColorBurn

Darkens the backdrop color to reflect the source color. Painting with white produces no change.

HardLight

public static final Blending HardLight

Multiplies or screens the colors, depending on the source color value. The effect is similar to shining a harsh spotlight on the backdrop.

SoftLight

public static final Blending SoftLight

Darkens or lightens the colors, depending on the source color value. The effect is similar to shining a diffused spotlight on the backdrop.

Difference

public static final Blending Difference

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

Exclusion

public static final Blending Exclusion

Produces an effect similar to that of the Difference mode but lower in contrast. Painting with white inverts the backdrop color; painting with black produces no change.

Hue

public static final Blending Hue

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

Saturation

public static final Blending Saturation

Creates a color with the saturation of the source color and the hue and luminosity of the backdrop color. Painting with this mode in an area of the backdrop that is a pure gray (no saturation) produces no change.

Color

public static final Blending Color

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

Luminosity

public static final Blending Luminosity

Creates a color with the luminosity of the source color and the hue and saturation of the backdrop color. This produces an inverse effect to that of the Color mode.

Method Details

values

public static Blending[] values()

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

Returns:

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