Radial node

pluginIcon

This documentation is for version 2.1 of Radial (net.sf.openfx.Radial).

Description

Radial ramp.

The ramp is composited with the source image using the ‘over’ operator.

If no source is connected, this effect behaves like a generator. Its region of definition is:

  • The selected format if the Extent parameter is a format.
  • The project output format if Color0 is not black and transparent.
  • The selected extent plus a one-pixel border if Color0 is black and transparent.

Controls

Parameter / script name Type Default Function
Extent / extent Choice Size
Extent (size and offset) of the output.
Format (format): Use a pre-defined image format.
Size (size): Use a specific extent (size and offset).
Project (project): Use the project extent (size and offset).
Default (default): Use the default extent (e.g. the source clip extent, if connected).
Center / recenter Button   Centers the region of definition to the input region of definition. If there is no input, then the region of definition is centered to the project window.
Reformat / reformat Boolean Off Set the output format to the given extent, except if the Bottom Left or Size parameters is animated.
