Gradient engine

Name: gradient. Output: SVG. Fills a shape with a gradient whose colors are derived from the seed.

Avatar::engine('gradient')
    ->seed('user@example.com')
    ->size(256)
    ->shape('circle')
    ->gradientType('diagonal')
    ->colorStops(3)
    ->generate();

Options

Option	Method	Type	Default
Shape	shape()	string	circle
Gradient type	gradientType()	string	horizontal
Color stops	colorStops()	int	3

shape accepts circle, square, or hexagon.

Gradient types

Value	Result
horizontal	Left-to-right linear gradient (default).
vertical	Top-to-bottom linear gradient.
diagonal	Corner-to-corner linear gradient.
radial	Radial gradient from the center.
wavy	Linear gradient with interleaved mid-stops.
marble	Layered, blurred "marble" composition.

The number of color stops is set by colorStops. Colors fan out from the seed's base hue across the requested number of stops.

Marble variant

When gradientType is marble, the engine renders two overlapping blurred shapes inside a masked frame. Two additional options are read from the option bag for this mode:

• A rotation value affects the hexagon mask shape.
• A marbleBlur integer controls the Gaussian blur amount (default 7).

The mask corners follow the shape option (circle, square, or hexagon).
