public enum BlendMode

Fields

Color = 14

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

This preserves the gray levels of the backdrop and is useful for coloring monochrome images or tinting color images.

ColorBurn = 7

Darkens the backdrop color to reflect the source color.

Painting with white produces no change.

ColorDodge = 6

Brightens the backdrop color to reflect the source color.

Painting with black produces no changes.

Darken = 4

Selects the darker of the backdrop and source colors.

The backdrop is replaced with the source where the source is darker; otherwise, it is left unchanged.

Difference = 10

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

Painting with white inverts the backdrop color; painting with black produces no change.

Exclusion = 11

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.

HardLight = 8

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

The effect is similar to shining a harsh spotlight on the backdrop.

Hue = 12

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

Lighten = 5

Selects the lighter of the backdrop and source colors.

The backdrop is replaced with the source where the source is lighter; otherwise, it is left unchanged.

Luminosity = 15

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.

Multiply = 1

The source color is multiplied by the destination color and replaces the destination.

The resultant color is always at least as dark as either the source or destination color.

Normal = 0

No blending takes place. The source color replaces the destination color.

Overlay = 3

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

Source colors overlay the backdrop while preserving its highlights and shadows.

Saturation = 13

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.

Screen = 2

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

The result color is always at least as light as either of the two constituent colors.

SoftLight = 9

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

The effect is similar to shining a diffused spotlight on the backdrop.
