Radial node


This documentation is for version 2.1 of Radial.


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.

Input Description Optional
Source   Yes
Mask   Yes


Parameter / script name Type Default Function
Extent / extent Choice Size
Extent (size and offset) of the output.
Format: Use a pre-defined image format.
Size: Use a specific extent (size and offset).
Project: Use the project extent (size and offset).
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.
Format / NatronParamFormatChoice Choice HD 1920x1080 The output format
Bottom Left / bottomLeft Double x: 0 y: 0 Coordinates of the bottom left corner of the size rectangle.
Size / size Double w: 1 h: 1 Width and height of the size rectangle.
Interactive Update / interactive Boolean Off If checked, update the parameter values during interaction with the image viewer, else update the values when pen is released.
Frame Range / frameRange Integer min: 1 max: 1 Time domain.
Softness / softness Double 1 Softness of the radial ramp. Draws an anti-aliased disc or ellipse if zero.
Perceptually Linear / plinear Boolean Off Make the radial ramp look more linear to the eye.
Color 0 / color0 Color r: 0 g: 0 b: 0 a: 0  
Color 1 / color1 Color r: 1 g: 1 b: 1 a: 1  
Expand RoD / expandRoD Boolean On Expand the source region of definition by the shape RoD (if Source is connected and color0=(0,0,0,0)).
Invert Mask / maskInvert Boolean Off When checked, the effect is fully applied where the mask is 0.
Mix / mix Double 1 Mix factor between the original and the transformed image.
