spreadMethod attribute determines how a shape is filled beyond the defined edges of a gradient.

You can use this attribute with the following SVG elements:

Context notes

值	`pad` \| `reflect` \| `repeat`
初始值	`pad`
Animatable	Yes

pad
reflect
repeat

Defining a gradient's edges

By default, a gradient reaches to the edges of the shape being filled. To see the effects of this attribute, you will need to set the size of the gradient smaller than the shape.

In the case of a linear gradient, the edges may be defined as a rectangle by the x1 , x2 , y1 and y2 attributes. In the case of a radial gradient, the edges may be defined as outer and inner circles by the cx , cy and r (outer) and fx , fy and fr (inner) attributes.
