Technical Specification & Mathematical Principles

Radial gradients interpolate color outward from an origin point (cx, cy): distance = √[(x - cx)² + (y - cy)²].

Color stops map monotonically along the radius r ∈ [0.0, r_max].

Frequently Asked Questions

A 'circle' gradient maintains a constant 1:1 aspect radius regardless of the container dimensions. An 'ellipse' gradient stretches proportionally to match the container's width and height.
