cairo-pattern-get-radial-circles (pattern)

pattern -- a cairo-pattern-t instance

x0 -- a double float x coordinate of the center of the first circle
y0 -- a double float y coordinate of the center of the first circle
r0 -- a double float radius of the first circle
x1 -- a double float x coordinate of the center of the second circle
y1 -- a double float y coordinate of the center of the second circle
r1 -- a double float radius of the second circle
status -- :success, or :pattern-type-mismatch if pattern is not a radial gradient pattern

Gets the gradient endpoint circles for a radial gradient, each specified as a center coordinate and a radius.
