 <script type="text/javascript">     $(function() {         setinterval(slideimage, 2000);     });      function slideimage() {         $("#imgreel").animate({ "margintop": "-=300px" }, 1000, function() { });     } </script>  <style type="text/css">     img     {         width: 600px;         height: 300px;     }     .imgcontainer     {         overflow: hidden;         width: 620px !important;         height: 300px !important;     }     div     {         width: 620px;     }     .current     {         z-index: 0;     }     .next     {         z-index: 1;     }     .imgreel     {         width: 620px !important;     }     . </style> 

<body> <div id="imgcontainer" class="imgcontainer">     <div id="imgreel" class="imgreel">         <div class="current">             <img src="images/summerwave.jpg" />         </div>         <div>             <img src="images/sunlight_and_the_wild_forest_floor.jpg" />         </div>         <div>             <img src="images/sunset.jpg" />         </div>         <div>             <img src="images/swimming_with_the_fishys.jpg" />         </div>         <div>             <img src="images/tearing_apart.jpg" />         </div>         <div>             <img src="images/teaser.jpg" />         </div>         <div>             <img src="images/terra_nova.jpg" />         </div>     </div> </div>

any appreciated

you can use other approach: let #imgreel fixed, , resize elements:

moving imgreel bottom, make if slideup element in top, appending before first element @ bottom (after last element), you'll have effect reel moving, disappearing top of current image first.

in code, using plugin scrollto:

var $reel = null; function init() {     $reel = $("#imgreel")     // keep first element first shown, we're going take reel bottom     $reel.children("div:first").insertafter($reel.children("div:last"))     // move bottom using scrollto or whatever want:     $reel.scrollto("max") }  function next() {     // clone first element (not visible) @ end     var $topelement = $reel.children("div:first")     var $bottomelement = $topelement.clone().appendto($reel)      // hide top element (cloned @ bottom) , remove when it's done     $topelement.slideup(1000, function() { $(this).remove() })      // mark next 'current'     $reel.children(".current").removeclass("current");     $bottomelement.addclass("current"); }

on other hand, if don't want make infinite loop, , keeping approach, using scrollto simple this:

funnction next() {     var $current = $reel.find("div.current").removeclass("current")     var $next = $current.next()     if(!$next.length) $next = $reel.children("div:first")     $reel.scrollto($next.addclass("current"), 1000) }  function prev() {     var $current = $reel.find("div.current").removeclass("current")     var $next = $current.prev()     if(!$next.length) $next = $reel.children("div:last")     $reel.scrollto($next.addclass("current"), 1000) })

hope helps :-)

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
