The IHTMLCSSStyleDeclaration::filter property is generally used to apply a previously define filter to an applicable element.
This property is read/write.
HRESULT put_filter( [in] DOMString val ); HRESULT get_filter( [out] DOMString **ptr );
Generally used to apply a previously defined filter to an element invoking the IHTMLCSSStyleDeclaration::filter property.
A functional IRI reference, such as
Do not apply any filter effects to this element (default value).
Indicates that the property takes the same computed value as the property for the element's parent.
Filter elements are never rendered directly; their only usage is as something that can be referenced using the IHTMLCSSStyleDeclaration::filter property. Be aware that filter elements are available for referencing even when the IHTMLCSSStyleDeclaration::display property on the filter element or any of its ancestors is set to none.
In the following example, a previously defined Gaussian_Blur filter (that is,
filter:url(#Gaussian_Blur)"/>) is being applied to an SVG ellipse:
<ellipse cx="200" cy="150" rx="70" ry="40" style="fill:#ff0000; stroke:#000000; stroke-width:2; filter:url(#Gaussian_Blur)"/>
