BrushPaint.TextureLayer.BlendMode

val DST: BrushPaint.TextureLayer.BlendMode

Keeps the destination pixels and discards the source pixels.

Alpha = Alpha_dst
Color = Color_dst

This mode is unlikely to be useful, since it effectively causes the renderer to just ignore this TextureLayer and all layers before it, but it is included for completeness.

val DST_ATOP: BrushPaint.TextureLayer.BlendMode

Discards destination pixels that aren't covered by source pixels. Remaining destination pixels are drawn over source pixels.

Alpha = Alpha_src
Color = Alpha_src * Color_dst + (1 - Alpha_dst) * Color_src

This mode shouldn't normally be used for the final TextureLayer, since its output alpha is not proportional to the destination alpha (so it wouldn't preserve alpha adjustments from anti-aliasing).

val DST_IN: BrushPaint.TextureLayer.BlendMode

Keeps destination pixels that cover source pixels. Discards remaining source and destination pixels.

Alpha = Alpha_src * Alpha_dst
Color = Alpha_src * Color_dst

val DST_OUT: BrushPaint.TextureLayer.BlendMode

Keeps the destination pixels not covered by source pixels. Discards destination pixels that are covered by source pixels and all source pixels.

Alpha = (1 - Alpha_src) * Alpha_dst
Color = (1 - Alpha_src) * Color_dst

val DST_OVER: BrushPaint.TextureLayer.BlendMode

The source pixels are drawn behind the destination pixels.

Alpha = Alpha_dst + (1 - Alpha_dst) * Alpha_src
Color = Color_dst + (1 - Alpha_dst) * Color_src

This mode shouldn't normally be used for the final TextureLayer, since its output alpha is not proportional to the destination alpha (so it wouldn't preserve alpha adjustments from anti-aliasing).

val MODULATE: BrushPaint.TextureLayer.BlendMode

Source and destination are component-wise multiplied, including opacity.

Alpha = Alpha_src * Alpha_dst
Color = Color_src * Color_dst

val SRC: BrushPaint.TextureLayer.BlendMode

Keeps the source pixels and discards the destination pixels.

Alpha = Alpha_src
Color = Color_src

This mode shouldn't normally be used for the final TextureLayer, since its output alpha is not proportional to the destination alpha (so it wouldn't preserve alpha adjustments from anti-aliasing).

val SRC_ATOP: BrushPaint.TextureLayer.BlendMode

Discards source pixels that do not cover destination pixels. Draws remaining pixels over destination pixels.

Alpha = Alpha_dst
Color = Alpha_dst * Color_src + (1 - Alpha_src) * Color_dst

val SRC_IN: BrushPaint.TextureLayer.BlendMode

Keeps the source pixels that cover destination pixels. Discards remaining source and destination pixels.

Alpha = Alpha_src * Alpha_dst
Color = Color_src * Alpha_dst

val SRC_OUT: BrushPaint.TextureLayer.BlendMode

Keeps the source pixels that do not cover destination pixels. Discards destination pixels and all source pixels that cover destination pixels.

Alpha = (1 - Alpha_dst) * Alpha_src
Color = (1 - Alpha_dst) * Color_src

This mode shouldn't normally be used for the final TextureLayer, since its output alpha is not proportional to the destination alpha (so it wouldn't preserve alpha adjustments from anti-aliasing).

val SRC_OVER: BrushPaint.TextureLayer.BlendMode

The source pixels are drawn over the destination pixels.

Alpha = Alpha_src + (1 - Alpha_src) * Alpha_dst
Color = Color_src + (1 - Alpha_src) * Color_dst

This mode shouldn't normally be used for the final TextureLayer, since its output alpha is not proportional to the destination alpha (so it wouldn't preserve alpha adjustments from anti-aliasing).

val XOR: BrushPaint.TextureLayer.BlendMode

Discards source and destination pixels that intersect; keeps source and destination pixels that do not intersect.

Alpha = (1 - Alpha_dst) * Alpha_src + (1 - Alpha_src) * Alpha_dst
Color = (1 - Alpha_dst) * Color_src + (1 - Alpha_src) * Color_dst

This mode shouldn't normally be used for the final TextureLayer, since its output alpha is not proportional to the destination alpha (so it wouldn't preserve alpha adjustments from anti-aliasing).
