A table containing entries which describe how the foreground will be merged over the background. All values are optional, and an empty table will perform a default Additive merge of the foreground over the background. Valid entries include:
MO_EdgeMode | "Black" "Canvas" "Wrap" "Duplicate" |
MO_ApplyMode | "Normal" "Merge" "Screen" "Dissolve" "Darken" "Multiply" "ColorBurn" "LinearBurn" "Darker Color" "Lighten" "ColorDodge" "LinearDodge" "LighterColor" "Overlay" "SoftLight" "HardLight" "VividColor" "LinearLight" "PinLight" "Difference" "Exclusion" "Hue" "Saturation" "Color" "Luminosity" "Hypotenuse" "Geometric" |
MO_ApplyOperator | "Over" "In" "HeldOut" "Atop" "XOr" "Conjoint" "Disjoint" "Mask" "Stencil" "Under" |
