<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"

  <!-- using my radial gradient -->

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

Deprecated: 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 兼容性表格 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 <radialGradient> element that will be used as a template. Value type : <IRI> ; 默认值 : none; Animatable : yes
