Gradient Controls Settings
 
 
 
Position X field
Displays the position of the gradient along the X axis.
Position Y field
Displays the position of the gradient along the Y axis.
Rotation field
Displays the degree of rotation of the gradient.
TipYou can also manipulate the position and rotation of the gradient directly in the image window if Show Widgets is enabled.
Scale field (not shown)
Displays the scale of the gradient.
Centre field (not shown)
Directional gradient only: Displays the offset value of the centre of the spline as a percentage of its position on the spline.
Amplitude field (not shown)
Directional gradient only: Displays the pixel length of the spline. You can also drag either end of the spline directly in the image window to affect the amplitude.
Roundness field
Radial gradient only: Displays the relative shape of the inner and outer circular patterns. A value of 1 displays the full rounded shape, whereas a value of 0 indicates a square shape. You can also enter a negative value to produce a concave shape.

You can further alter the shape of a radial gradient with the Shape settings.

Sharpness field (not shown)
Point gradient only: Displays the level of edge sharpness between the gradient point colours.
Softness field
Displays the level of blur added to the gradient. A higher value produces a smoother transition between gradient colours.
Extrapolation box
Select an extrapolation type for the gradient pattern.
Select: To:
Constant Keep the last value as a solid colour.
Repeat Repeat the same gradient pattern.
Mirror Repeat the gradient pattern in reverse order until the frame border is reached.
Offset Cycle field
Displays the cycle position of the color creating the gradient.
