filtertype2 (parameter1, parameter2,...) Any filter listed in the Visual Filters and Transitions Reference.
The property is read/write. The property has no default value. The Cascading Style Sheets (CSS) attribute is not inherited.

remarks

an object must have layout for the filter to render. a simple way to accomplish this is to give the element a specified height and/or width. however, there are several other properties that can give an element layout. for more information on these other properties, see the haslayout property.
the shadow filter can be applied to the img object by setting the filter on the image's parent container.
the filter mechanism is extensible and enables you to develop and add additional filters later. for more information about filters, see introduction to filters and transitions.
not available on the macintosh platform.

Examples

progid:DXImageTransform.Microsoft.BasicImage(mirror=1)"
src="/workshop/samples/author/dhtml/graphics/cone.jpg"
height="80px" width="80px" border="0" alt="cone">
