This visual filter removes all color information from the filtered element and displays it in grayscale mode only. There are no properties associated with it.
The use of this filter is now deprecated in favor of the BasicImage() filter that was implemented with the IE 5.5 browser.
Filters are defined in style sheets as if they were a function call with its arguments expressed as name=value pairs. This is not the typical way to define arguments so you should be aware of this anomaly when working with filters.
