BrushPaint.TextureLayer.BlendMode
public final class BrushPaint.TextureLayer.BlendMode
The method by which the combined texture layers (index <= i) are blended with the next layer. The blend mode on the final layer controls how the combined texture is blended with the brush color, and should typically be a mode whose output alpha is proportional to the destination alpha, so that it can be adjusted by anti-aliasing.

DST
public static final @NonNull BrushPaint.TextureLayer.BlendMode DST
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.
DST_ATOP
public static final @NonNull BrushPaint.TextureLayer.BlendMode DST_ATOP
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).
DST_IN
public static final @NonNull BrushPaint.TextureLayer.BlendMode DST_IN
Keeps destination pixels that cover source pixels. Discards remaining source and destination pixels.
Alpha = Alpha_src * Alpha_dst
Color = Alpha_src * Color_dstDST_OUT
public static final @NonNull BrushPaint.TextureLayer.BlendMode DST_OUT
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_dstDST_OVER
public static final @NonNull BrushPaint.TextureLayer.BlendMode DST_OVER
The source pixels are drawn behind the destination pixels.
Alpha = Alpha_dst + (1 - Alpha_dst) * Alpha_src
Color = Color_dst + (1 - Alpha_dst) * Color_srcThis 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).
MODULATE
public static final @NonNull BrushPaint.TextureLayer.BlendMode MODULATE
Source and destination are component-wise multiplied, including opacity.
Alpha = Alpha_src * Alpha_dst
Color = Color_src * Color_dstSRC
public static final @NonNull BrushPaint.TextureLayer.BlendMode SRC
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).
SRC_ATOP
public static final @NonNull BrushPaint.TextureLayer.BlendMode SRC_ATOP
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
SRC_IN
public static final @NonNull BrushPaint.TextureLayer.BlendMode SRC_IN
Keeps the source pixels that cover destination pixels. Discards remaining source and destination pixels.
Alpha = Alpha_src * Alpha_dst
Color = Color_src * Alpha_dstSRC_OUT
public static final @NonNull BrushPaint.TextureLayer.BlendMode SRC_OUT
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_srcThis 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).
SRC_OVER
public static final @NonNull BrushPaint.TextureLayer.BlendMode SRC_OVER
The source pixels are drawn over the destination pixels.
Alpha = Alpha_src + (1 - Alpha_src) * Alpha_dst
Color = Color_src + (1 - Alpha_src) * Color_dstThis 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).
XOR
public static final @NonNull BrushPaint.TextureLayer.BlendMode XOR
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).
