clip-rule

« SVG Attribute reference home

The clip-rule attribute only applies to graphics elements that are contained within a <clipPath> element. The clip-rule attribute basically works as the fill-rule attribute, except that it applies to <clipPath> definitions.

The following fragment of code will cause an evenodd clipping rule to be applied to the clipping path because clip-rule is specified on the <path> element that defines the clipping shape:

html

<g>
  <clipPath id="MyClip">
    <path d="..." clip-rule="evenodd" />
  </clipPath>
  <rect clip-path="url(#MyClip)" ... />
</g>

whereas the following fragment of code will not cause an evenodd clipping rule to be applied because the clip-rule is specified on the referencing element, not on the object defining the clipping shape:

html

<g>
  <clipPath id="MyClip">
    <path d="..." />
  </clipPath>
  <rect clip-path="url(#MyClip)" clip-rule="evenodd" ... />
</g>

As a presentation attribute, it also can be used as a property directly inside a CSS stylesheet

Usage notes

  </defs>

  <!-- Left: evenodd -->
  <clipPath id="emptyStar">
    <use href="#star" clip-rule="evenodd" />
  </clipPath>
  <rect clip-path="url(#emptyStar)" width="50" height="90" fill="blue" />

  <!-- Right: nonzero -->
  <clipPath id="filledStar">
