Question

mootools (or similar) blur effect on background image

Asked by: socross

Hi

I really need to find a way to apply a blur to background images using any method possible.

I need to be able to call and apply the blur/pixelatted effect from within a function, the background image will be contained within a div.

Please say its possible, anything i have found so far just cant seem to do it!

I did find this that could be adapted but i have no idea where to start.

If you look at the source code of that page, it is very clear. Basically, if you replicate the HTML markup, you would only need to use the appropriate URL to your image. However, you need this to work on a background, you would need your content to be on a div with absolute position and a z-index large enough so that it appear on top of your image. So strictly speaking your image will not really be a background image. It would just give the impression that it is a background image.

ok

i might have some issues because i have implemented a javascript gallery which runs in the background of my site, the bg div with the images in the background  has images changed dynamically when the gallery is live.

Ideally i need to have the blur applied to the image when the page loads and then when the view gallery button is pressed i need to be able turn the blur off, the gallery can then be viewed and then blur swiched back on when the return to content button is pressed.

Is there any way to apply it to a background image or will i need to rethink my design.

If so could i show you my dev site?

Thanks

Hmmm. After looking at it, the blurring effect is applied to an object. Specifically and <img> object. A background is not really an object. It's a property of an object. Specifically, its a CSS property. From javascripts point of view, it the style.backgroundImage holds a "string" value that "points" to some image. Since the script actually operates on an <img> object, you may have to rethink your design.
Post your dev site and I'll take a look at it later.

Specify EXACTLY and most importantly, CLEARLY what it is that you want to achieve.
