Gradient Filter

This topic documents a feature of Visual Filters and Transitions, which is deprecated as of Windows Internet Explorer 9.

Displays a color gradient between the object's background and content.

Syntax

HTML
<ELEMENT STYLE=
"filter:progid:DXImageTransform.Microsoft.Gradient(sProperties)"
... >
Internet Explorer 5.5 or later
Scripting
object .style.filter =
"progid:DXImageTransform.Microsoft.Gradient(sProperties)"
Internet Explorer 5.5 or later

Possible Values

sProperties String that specifies one or more properties exposed by the filter.

Members Table

The following table lists the members exposed by the Gradient object.

Attributes/Properties
Attribute Property Description
enabled Enabled

Sets or retrieves a value that indicates whether the filter is enabled.

EndColor

Sets or retrieves the final opaque color for a gradient surface.

EndColorStr

Sets or retrieves the final color for a gradient surface.

GradientType

Sets or retrieves the orientation of the gradient.

StartColor

Sets or retrieves the initial opaque color for a gradient surface.

startColorStr StartColorStr

Sets or retrieves the initial color for a gradient surface.

Remarks

When revealed by a transition, any text that covers a Gradient procedural surface is initially exposed as transparent. After the transition has finished, the text is updated to the applicable color.

The object that the filter is applied to must have layout before the filter effect will display. You can give the object layout by setting the height or width property, setting the position property to absolute, setting the writingMode property to tb-rl, or setting the contentEditable property to true.

You can assign multiple filters or transitions to an object by declaring each in the filter property of the object. The following div declaration assigns two filters and a Wheel transition to a div element.


<DIV STYLE="width:100%; filter:
    progid:DXImageTransform.Microsoft.MotionBlur(strength=13, direction=310)
    progid:DXImageTransform.Microsoft.Blur(pixelradius=2)
    progid:DXImageTransform.Microsoft.Wheel(duration=3);">
        Blurry text with smudge of gray.</div>     
When multiple filters are applied to an object, each filter is processed in source order, with the exception of procedural surfaces, which are computed first. To emphasize a filter's effect, place it last in source order or on the object's parent. Always place transitions last in source order.

Examples

The following example shows the effects of this filter when its properties are modified.

This example shows how the text is unaffected by the gradient behind it.



<SCRIPT>

<!-- Toggle the Enabled property to toggle the gradient.  -->
function fnToggle(oObj) {
    if (oDiv.filters(0).enabled){
        oDiv.filters(0).enabled='false';
        oObj.innerText='Add Gradient';}
    else {                                                        
        oDiv.filters(0).enabled='true';
        oObj.innerText='Make Normal';}
}
</SCRIPT>

<font size="+5">
    <DIV ID="oDiv" STYLE="height:120px; color:green; filter: 
            progid:DXImageTransform.Microsoft.gradient(enabled='false',
                startColorstr=#550000FF, endColorstr=#55FFFF00)" >
        A simple gradient   
    </DIV>
</font>
<P>
<BUTTON onclick="fnToggle(this)">Add Gradient</BUTTON><BR/>
