WebDec 17, 2024 · Gradient The right-hand side of Equation 2.7.4 is equal to fx(x, y)cosθ + fy(x, y)sinθ, which can be written as the dot product of two vectors. Define the first vector as ⇀ ∇ f(x, y) = fx(x, y)ˆi + fy(x, y)ˆj and the second vector as ⇀ u = (cosθ)ˆi + (sinθ)ˆj. WebAdds an opaque color stop to a gradient pattern. The offset ofs specifies the location along the gradient's control vector (default: 0.0).For example, a linear gradient's control vector is from (x0,y0) to (x1,y1) while a radial gradient's control vector is from any point on the start circle to the corresponding point on the end circle.
