Layer Shaders
- Layer_add
- Adds the colors of the foreground and background layer.
- Layer_blend
- Linearly blends between foreground and background layer using the float parameter 'mix'.
- Layer_color
- Layers the foreground input over the background input, replacing hue and saturation of the foreground with that of the background.
- Layer_color_burn
- Layers the foreground input over the background input, darkening the foreground color by a factor of the luminance of the background (may not work well for values less than 0 or greater than 1).
- Layer_color_dodge
- Layers the foreground input over the background input, lightening the foreground by a factor of the luminance of the background (may not work well for values less than 0 or greater than 1).
- Layer_darken
- Layers the foreground input over the background input, choosing the minimum value between the foreground and the background.
- Layer_difference
- Layers the foreground input over the background input, computing the absolute difference between the foreground and the background.
- Layer_dissolve
- Layers the foreground input over the background input, using a biased random decision at each pixel to choose between the foreground and the background.
- Layer_exclusion
- Layers the foreground input over the background input, computing the absolute difference between foreground and background, but at slightly lower contrast than the difference equation (may not work well for values less than 0 or greater than 1).
- Layer_hard_mix
- Layers the foreground input over the background input as a combination of a lighten operation and a darken operation with values below 0.5 being darkened and values above 0.5 being lightened.
- Layer_hue
- Layers the foreground input over the background input, replacing hue of the foreground with that of the background.
- Layer_lighten
- Layers the foreground input over the background input, choosing the maximum value between the foreground and the background.
- Layer_linear_burn
- Layers the foreground input over the background input as a combination of a color burn operation and a multiply operation.
- Layer_linear_dodge
- Layers the foreground input over the background input as a combination of a color dodge operation and a screen operation.
- Layer_linear_light
- Layers the foreground input over the background input as a combination of a linear burn and a linear dodge operation with values below 0.5 being combined using linear burn and values above 0.5 being combined using linear dodge.
- Layer_luminosity
- Layers the foreground input over the background input, replacing luminosity of the foreground with that of the background.
- Layer_multiply
- Multiplies the foreground and the background color.
- Layer_overlay
- Layers the foreground input over the background input as a combination of a screen operation and a multiply operation with values below 0.5 combined using multiply and values above 0.5 being combined using screen.
- Layer_pin_light
- Layers the foreground input over the background input as a combination of a lighten operation and a darken operation; instead of blending, this operation chooses between input values selecting two types of values: those below 0.5 in the foreground and less than the value of the background, and those above 0.5 in the foreground and greater than the value of the background.
- Layer_posterize
- Allows the input color to be displayed using only one of the number of input levels specified.
- Layer_saturation
- Layers the foreground input over the background input, replacing the saturation of the foreground with that of the background.
- Layer_screen
- Layers the foreground input over the background input, lightening the foreground based on the background; inverts both the foreground and background, multiplies those results, and then inverts that result.
- Layer_soft_light
- Layers the foreground input over the background input as a combination of a color dodge operation and a color burn operations with values below 0.5 being combined using color burn and values above 0.5 being combined using color dodge (may not work well for values less than 0 or greater than 1).
- Layer_vivid_light
- Layers the foreground input over the background input, enhancing and reducing contrast for different parts of the image with values below 0.5 darkened by increasing contrast and values above 0.5 lightened by decreasing contrast (may not work well for values less than 0 or greater than 1).
