    "DXImageTransform.Microsoft.filter-name").Strength [ = iDistance ]

Possible Values

Default.

The property is read/write. The property has a default value of 5 for all objects with the following exceptions:

The following table defines the limitations on the range of iDistance depending on the filter used.

Example

This example sets the Strength and Direction properties of the MotionBlur filter to an initial strength of 1. When the page loads, the Strength and Direction properties cause the onfilterchange event to fire repeatedly until the strength reaches 200.

<SCRIPT>
function HandleChange()
{
   with (window.event.srcElement.filters[0])
   {
      if (strength < 200)
      {
         strength += 1;
         direction += 45;
      }
   }
}</SCRIPT>
<IMG ID="img1" SRC="solarsys.gif" onfilterchange="HandleChange()"
   STYLE="filter:progid:DXImageTransform.Microsoft.motionBlur(STRENGTH=1, DIRECTION=0)" />
