<radialGradient> - SVG: Scalable Vector Graphics 编辑

The <radialGradient> element lets authors define radial gradients that can be applied to fill or stroke of graphical elements.

Don't be confused with CSS radial-gradient() as CSS gradients can only apply to HTML elements where SVG gradient can only apply to SVG elements.

html,body,svg { height:100% }
<svg viewBox="0 0 10 10" xmlns="http://www.w3.org/2000/svg"
     xmlns:xlink="http://www.w3.org/1999/xlink">
  <defs>
    <radialGradient id="myGradient">
      <stop offset="10%" stop-color="gold" />
      <stop offset="95%" stop-color="red" />
    </radialGradient>
  </defs>

  <!-- using my radial gradient -->
  <circle cx="5" cy="5" r="4" fill="url('#myGradient')" />
</svg>

Attributes

cx
This attribute defines the x coordinate of the end circle of the radial gradient.
Value type: <length> ; Default value: 50%; Animatable: yes
cy
This attribute defines the y coordinate of the end circle of the radial gradient.
Value type: <length> ; Default value: 50%; Animatable: yes
fr
This attribute defines the radius of the start circle of the radial gradient. The gradient will be drawn such that the 0% <stop> is mapped to the perimeter of the start circle.
Value type: <length> ; Default value: 0%; Animatable: yes
fx
This attribute defines the x coordinate of the start circle of the radial gradient.
Value type: <length> ; Default value: Same as cx; Animatable: yes
fy
This attribute defines the y coordinate of the start circle of the radial gradient.
Value type: <length> ; Default value: Same as cy; Animatable: yes
gradientUnits
This attribute defines the coordinate system for attributes x1, x2, y1, y2
Value typeuserSpaceOnUse|objectBoundingBox ; Default value: objectBoundingBox; Animatableyes
gradientTransform
This attribute provides additional transformation to the gradient coordinate system.
Value type: <transform-list> ; Default value: identity transform; Animatableyes
href
This attribute defines a reference to another <linearGradient> element that will be used as a template.
Value type: <URL> ; Default value: none; Animatable: yes
r
This attribute defines the radius of the end circle of the radial gradient. The gradient will be drawn such that the 100% <stop> is mapped to the perimeter of the end circle.
Value type: <length> ; Default value: 50%; Animatable: yes
spreadMethod
This attribute indicates how the gradient behaves if it starts or ends inside the bounds of the shape containing the gradient.
Value type: pad|reflect|repeat ; Default value: pad; Animatableyes
xlink:href

Deprecated since SVG 2

This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

An <IRI> reference to another <linearGradient> element that will be used as a template.
Value type: <IRI> ; Default value: none; Animatable: yes
