Fill node


This documentation is for version 1.0 of Fill.


Add a constant color on the source image where the alpha channel not 0. You can control the blending between the original image and the constant color with the operator and the mix factor.

Operation / Merge1operation Choice over

atop: Ab + B(1 - a) (a.k.a. src-atop)
average: (A + B) / 2
color: SetLum(A, Lum(B))
color-burn: darken B towards A
color-dodge: brighten B towards A
conjoint-over: A + B(1-a)/b, A if a > b
copy: A (a.k.a. src)
difference: abs(A-B) (a.k.a. absminus)
disjoint-over: A+B(1-a)/b, A+B if a+b < 1
divide: A/B, 0 if A < 0 and B < 0
exclusion: A+B-2AB
freeze: 1-sqrt(1-A)/B
from: B-A (a.k.a. subtract)
geometric: 2AB/(A+B)
grain-extract: B - A + 0.5
grain-merge: B + A - 0.5
hard-light: multiply if A < 0.5, screen if A > 0.5
hue: SetLum(SetSat(A, Sat(B)), Lum(B))
hypot: sqrt(A*A+B*B)
in: Ab (a.k.a. src-in)
luminosity: SetLum(B, Lum(A))
mask: Ba (a.k.a dst-in)
matte: Aa + B(1-a) (unpremultiplied over)
max: max(A, B) (a.k.a. lighten only)
min: min(A, B) (a.k.a. darken only)
minus: A-B
multiply: AB, 0 if A < 0 and B < 0
out: A(1-b) (a.k.a. src-out)
over: A+B(1-a) (a.k.a. src-over)
overlay: multiply if B < 0.5, screen if B > 0.5
pinlight: if B >= 0.5 then max(A, 2*B - 1), min(A, B * 2.0 ) else
plus: A+B (a.k.a. add)
reflect: A*A / (1 - B)
saturation: SetLum(SetSat(B, Sat(A)), Lum(B))
screen: A+B-AB if A or B <= 1, otherwise max(A, B)
soft-light: burn-in if A < 0.5, lighten if A > 0.5
stencil: B(1-a) (a.k.a. dst-out)
under: A(1-b)+B (a.k.a. dst-over)
xor: A(1-b)+B(1-a)
