Zigzag Transition (filter)

Last updated: October 30th, 2008

The Zigzag Transition reveals new content by revealing it line by line, from top to bottom, left to right, in a zigzag motion.. Defined via IE's CSS filter property and applied through JavaScript, here is its basic syntax:

Syntax:

filter: progid:DXImageTransform.Microsoft.Zigzag(attribute1=value1, attribute2=value2, etc);

Syntax (post IE8):

-ms-filter: "progid:DXImageTransform.Microsoft.Zigzag(attribute1=value1, attribute2=value2, etc)";

Note: See "Difference in syntax between pre IE8 and IE8+ browsers" for more info on the changes to the filter syntax in IE8+.

Example:

<style type="text/css">

#somediv{
width: 90%;
-ms-filter: "progid:DXImageTransform.Microsoft.Zigzag(duration=3)";
filter: progid:DXImageTransform.Microsoft.Zigzag(duration=3);
}

</style>


<div id="somediv">Some DIV</div>

Syntax Via Scripting

//To define a new Zigzag filter on an element
object.style.filter ="progid:DXImageTransform.Microsoft.Zigzag(attribute=value1, attribute2=value2)"

To access an existing property within the Zigzag filter:
object.filters.item("DXImageTransform.Microsoft.Zigzag").Property1=value1;

//To access an existing property within the Zigzag filter via the filters[] object
object.filters[x].Property1=value1 //where "x" is the position of the filter within list of filters on element

Below lists the attributes/properties of the Zigzag Transition:

Zigzag Transition attributes (properties)

Attributes/ Properties Description
duration Sets the duration of time the transition takes to complete, in seconds. No default value.

Valid values: Floating point number greater than 0 (seconds implied, ie: 2.5 means 2.5 seconds)

enabled Sets/ returns whether the filter is enabled or not.

Valid values: true/ false

gridSizeX, gridSizeY Sets the number of grid columns and rows, respectively, on the content to apply the filter using. Default is 16 and 16.

Valid values: 1 - 100 (for both properties)

Percent

* This property accessible via scripting only

Sets the point in which to capture the display of the content to apply the transition on. Default is 0.

Valid values: 0 - 100 (percentage implied)

status

* This property accessible via scripting only

Returns the current state of the transition.

Valid values:

Value description
0 Transition has stopped.
1 Transition has been successfully applied.
2 Transition is playing.

Example:

<script type="text/javascript">
var mydiv=document.getElementById("test")
alert(mydiv.filters.item("DXImageTransform.Microsoft.Zigzag").status) //alerts status of transition
</script>

Zigzag Transition methods

Methods Description
apply() Captures the initial display of the content in preparation for the transition to be played (using the play() method). No visible changes to the content made at this point.
play([duration]) Plays the transition in question. Supports an optional duration parameter that, if set, overrides the value of the duration property above in specifying the duration of the transition (in seconds).

In this following example, the Zigzag transition is used to transition between a DIV that's changing its background color from "blue" to "red".

Example:

<style type="text/css">

#mycontent{
-ms-filter: "progid:DXImageTransform.Microsoft.Zigzag(duration=3, gridSizeX=5, gridSizeY=5)";
filter :progid:DXImageTransform.Microsoft.Zigzag(duration=3, gridSizeX=5, gridSizeY=5);
width:150px;
height:150px;
background-color:blue;
}

</style>


<div id="mycontent" />
Some Div.
</div>

<script type="text/javascript">

var divbox=document.getElementById("mycontent")
divbox.filters[0].apply() //capture initial state of DIV (screenshot)
divbox.style.backgroundColor="red" //change DIV's bgColor to "red" (though changes not visible yet due to above capture
divbox.filters[0].play() //play transition to reveal updated content

</script>

stop() Stops the transition playback.
