Operators

The Layer Editor in Black Ink uses a nodal system, providing both non-destructive functionality and considerable flexibility for creations.
To compose an image, various operators are available and organized into six families: Output, Source, Adjustment, Mix, Effects, and Transformation.

Here is a list of the operators available in Black Ink:

Operator	Description
OUTPUT	These operators allow finalizing a step or a drawing.
Output image	Generates the final image of the drawing and cannot be connected to another node afterward.
SOURCE	These operators are the initial input data used in the creative process.
Color	Fills the canvas with an adjustable color that extends to your drawing area.
Layer Grayscale	An opaque grayscale layer that extends based on the drawing.
Layer	Draw freely on a layer, covering it or leaving areas transparent.
MIX	These operators blend multiple inputs together.
Blend	Overlays a foreground and background.
Layer Stack	Stacks multiple layers with different blending modes to compose your drawing.
Mask	Uses a source image to create another with transparencies, preserving the original.
TRANSFORM	These operators enable moving, rotating, scaling, repeating, cycling a source, etc.
Domain Wrap	Enables the drawing to fold back on itself.
Symmetry	Allows drawing with an adjustable symmetry axis without being destructive.
Radial symmetry	The symmetry operator allows for drawing with multiple radial symmetry axes.
Tiling	Duplicates a drawing as a pattern and defines the spacing between each repetition.
Transform	Moves, rotates, distorts, and resizes an image.
ADJUSTMENT	These operators adjust the visual properties of your drawing.
Brightness & Contrast	Adjusts the brightness and contrast of the image.
Color Channel	Adjusts individual color channels.
Color overlay	Applies a color overlay to the image.
Color posterization	Reduces the number of colors in the image, creating a posterized effect.
Color select	Selects and isolates specific colors.
Gradient map	Maps the colors of an image to a gradient.
