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

注意： 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.

范例

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>

								

属性

cx

This attribute defines the x coordinate of the end circle of the radial gradient. Value type : <length> ; 默认值 : 50% ; Animatable : yes

cy

This attribute defines the y coordinate of the end circle of the radial gradient. Value type : <length> ; 默认值 : 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> ; 默认值 : 0% ; Animatable : yes

fx

This attribute defines the x coordinate of the start circle of the radial gradient. Value type : <length> ; 默认值 : Same as cx ; Animatable : yes

fy

This attribute defines the y coordinate of the start circle of the radial gradient. Value type : <length> ; 默认值 : Same as cy ; Animatable : yes

gradientUnits

This attribute defines the coordinate system for attributes cx , cy , r , fx , fy , fr Value type :  userSpaceOnUse | objectBoundingBox ; 默认值 : objectBoundingBox ; Animatable :  yes

gradientTransform

This attribute provides additional transformation to the gradient coordinate system. Value type : <transform-list> ; 默认值 : identity transform ; Animatable :  yes

href

This attribute defines a reference to another <radialGradient> element that will be used as a template. Value type : <URL> ; 默认值 : 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> ; 默认值 : 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 ; 默认值 : pad ; Animatable :  yes

xlink:href

An <IRI> reference to another <radialGradient> element that will be used as a template. Value type : <IRI> ; 默认值 : none; Animatable : yes
