NEW IN R21
Here the line drawn on the selected background color will be output.
These grayscales will be output as a gradient between the center of the line and its outer edge. The line’s blur will not play a role. The center of the line will appear black and its brightness will transition to white to the edge.
Here, grayscales will be output, which can, for example, be used to mask out the line using a Compose ColorA node. The blurring of the line will be included in the calculation.
