  • Artigo

Sets or retrieves the direction that the filter's effect is offset.

Syntax

HTML
{ filter:progid:DXImageTransform.Microsoft.filter-name(
    direction = iOffset ... ) ... }
Scripting
object.filters.item(
    "DXImageTransform.Microsoft.filter-name").Direction [ = iOffset ]

Possible Values

iOffset Integer that specifies or receives the direction of the offset, in degrees. This can be one of the following values.

The property is read/write. The property has a default value of 270 for all objects with the exception of Shadow which has a default value of 225.

Remarks

Values less than 0 or greater than 360 automatically convert to values between 0 and 360 . For example, a value of -45 degrees is equivalent to a value of 315 degrees.

Example

This example sets the Direction and Strength properties of the MotionBlur filter for an image, with an initial strength of 1. When the page loads, the onfilterchange event of the image fires. The onfilterchange event fires each time the Strength and Direction properties change, until Strength reaches a value of 100.

<SCRIPT>
function HandleChange()
{
   with (window.event.srcElement.filters[0])
   {
      if (strength < 100)
      {
         strength += 1;
         direction += 45;
      }
   }
}</SCRIPT>
<IMG ID="img1" SRC="solarsys.gif" onfilterchange="HandleChange()"
   STYLE="filter:progid:DXImageTransform.Microsoft.MotionBlur(
STRENGTH=1, DIRECTION=0)" />
