Declaration:

 
Copy Code
AT_ERRCOUNT ACCUAPI IG_vect_gradient_radial_set_vector(
        HIG_VECT_GRADIENT hGradient,
        IGVectPoint3D ptIn, 
        IGVectPoint3D ptOut, 
        VECT_REAL fRadius, 
        AT_BOOL bAbsolute
);

Arguments:

Name Type Description
hGradient HIG_VECT_GRADIENT Handle to a gradient object.
ptIn IGVectPoint3D Coordinates of the center of the inner circle.
ptOut IGVectPoint3D Coordinates of the center of the outer circle.
fRadius VECT_REAL Radius of the outer circle.
bAbsolute AT_BOOL Specifies whether circle coordinates and radius are relative or absolute.
