Ramp
The Ramp node generates a linear gradient between two edges. You can set the
direction of the ramp to horizontal or vertical. The Ramp is, among other things, a useful
tool for analyzing color-correction nodes. Attach a horizontal Ramp node to any of the
color-correction nodes, then attach the color-correction node to a PlotScanline node. For
a radial gradient, use the RGrad node. For a four-corner ramp, use the Grad node.
Parameters
