|---|---|---|---|---|---|---|---|---|---|---|---|
| BlendMode | COLOR_BURN | Darkens the backdrop colour to reflect the source colour. | |||||||||
| BlendMode | COLOR_DODGE | Brightens the backdrop colour to reflect the source colour. | |||||||||
| BlendMode | DARKEN | B(cb, cs) = min(cb, cs) Selects the darker of the backdrop and source colours. | |||||||||
| BlendMode | DIFFERENCE | B(cb,cs) = cb–cs Subtracts the darker of the two constituent colours from the lighter colour: Painting with white inverts the backdrop colour; painting with black produces no change. | |||||||||
| BlendMode | EXCLUSION | B(cb,cs) = cb+cs–2×cb×cs Produces an effect similar to that of the Difference mode but lower in contrast. | |||||||||

Enum Values
public static final BlendMode COLOR_BURN
Darkens the backdrop colour to reflect the source colour. Painting with white produces no change.
public static final BlendMode COLOR_DODGE
Brightens the backdrop colour to reflect the source colour. Painting with black produces no changes.
public static final BlendMode DARKEN
B(cb, cs) = min(cb, cs) Selects the darker of the backdrop and source colours. The backdrop is replaced with the source where the source is darker; otherwise, it is left unchanged.
See also PorterDuff.Mode#DARKEN
public static final BlendMode DIFFERENCE
B(cb,cs) = cb–cs Subtracts the darker of the two constituent colours from the lighter colour: Painting with white inverts the backdrop colour; painting with black produces no change.
public static final BlendMode EXCLUSION
B(cb,cs) = cb+cs–2×cb×cs Produces an effect similar to that of the Difference mode but lower in contrast. Painting with white inverts the backdrop colour; painting with black produces no change.
public static final BlendMode HARD_LIGHT
Multiplies or screens the colours, depending on the source colour value. The effect is similar to shining a harsh spotlight on the backdrop.
public static final BlendMode LIGHTEN
B(cb, cs) = max(cb, cs) Selects the lighter of the backdrop and source colours. The backdrop is replaced with the source where the source is lighter; otherwise, it is left unchanged.
See also PorterDuff.Mode#LIGHTEN
public static final BlendMode MULTIPLY
B(cb,cs) = cb×cs Multiplies the backdrop and source colour values. The result colour is always at least as dark as either of the two constituent colours. Multiplying any colour with black produces black; multiplying with white leaves the original colour unchanged. Painting successive overlapping objects with a colour other than black or white produces progressively darker colours.
See also PorterDuff.Mode#MULTIPLY
public static final BlendMode NORMAL
B(cb,cs) = cs Selects the source colour, ignoring the backdrop.
See also PorterDuff.Mode#SRC
public static final BlendMode OVERLAY
B(cb, cs) = HardLight(cs, cb) Multiplies or screens the colours, depending on the backdrop colour value. Source colours overlay the backdrop while preserving its highlights and shadows. The backdrop colour is not replaced but is mixed with the source colour to reflect the lightness or darkness of the backdrop.
See also PorterDuff.Mode#OVERLAY
public static final BlendMode SCREEN
B(cb,cs) = 1 – [(1–cb)×(1–cs)] = cb + cs – (cb × cs) Multiplies the complements of the backdrop and source colour values, then complements the result. The result colour is always at least as light as either of the two constituent colours. Screening any colour with white produces white; screening with black leaves the original colour unchanged. The effect is similar to projecting multiple photographic slides simultaneously onto a single screen.
See also PorterDuff.Mode#SCREEN
public static final BlendMode SOFT_LIGHT
Darkens or lightens the colours, depending on the source colour value. The effect is similar to shining a diffused spotlight on the backdrop.
