Using SVG effectsYou can use SVG effects to add graphic properties such as drop shadows to your artwork. SVG filters differ from their bitmap counterparts in that they are XML-based and resolution-independent. In fact, an SVG effect is nothing more than a series of XML properties that describe various mathematical operations. The resulting effect is rendered to the target object instead of the source graphic. Illustrator provides a default set of SVG effects. You can use the effects with their default properties, edit the XML code to produce custom effects, or write new SVG filters. Important: An SVG effect must be the last effect when an object uses multiple effects; in other words, it must appear at the bottom of the Appearance palette (just above the Transparency entry). If other effects follow an SVG effect, the SVG output will consist of a raster object. To apply an SVG effect:
Note: When you apply an SVG filter effect, Illustrator displays a rasterized version of the effect on the artboard. You can control the resolution of this preview image by modifying the document's rasterization resolution setting. (See Specifying raster effects settings.) To import SVG filter definitions into a document:
To delete an SVG filter:
Do one of the following: To modify Illustrator's default SVG filters: Use a text editor to edit the Adobe SVG Filters.svg file in the Plug-ins folder inside the Adobe Illustrator application folder. You can modify existing filter definitions, delete filter definitions, and add new filter definitions. |
