Altering the hue of a picture

Altering the hue of a picture

Looking to alter the color of an image on a webpage, specifically a carport. It's crucial that the texture and shadows remain consistent. Swapping out images with different colors would require an excessive amount of images, so I'm seeking advice from the community on whether there is a jQuery code available that can apply a color filter to change the color of a white carport in real-time on the website.

Here is one of the images I'll be working with:

The roof part of the image is the only element that needs to change color; the metal rails and background must stay the same.

Update: Considering using flash for this project may be more efficient. Are there any recommended tutorials for incorporating flash into websites?

Another option is to utilize PHP for generating the image by using the imagecopymerge function. This method allows you to conveniently adjust the color filter and image directly in the URL:

<img src="generateimage.php?img=house&color=green" />

Add a transparent overlay to your image and adjust the background accordingly. In this demonstration, I utilized jQuery to change colors upon button click. Various CSS transparency properties were also applied for a comprehensive cross-browser solution.

Opacity settings for optimal compatibility across different browsers, including IE6

.opacity{
    -khtml-opacity:.20;
    -moz-opacity:.20;
    -ms-filter:”alpha(opacity=20)”;
    filter:alpha(opacity=20);
    filter: progid:DXImageTransform.Microsoft.Alpha(opacity=0.2);
    opacity:.20;
}

Here is the jQuery code that alters the color when a button is clicked.

$('#red, #green, #yellow, #blue').click(function(e) {
    var x = e.target.id;
    $('.filter').css({'background': x})
})

Imagine you have the following HTML structure:

<div id="gallery">
    <img src="http://farm2.static.flickr.com/1157/1054046043_82c48223f1.jpg" />
    <div id="overlay"></div>
</div>
<ul id="colors">
    <li>Red</li>
    <li>Green</li>
</ul>

Here is the accompanying CSS:

#gallery {
    position: relative;
    display: inline-block;
    margin: 0 auto;
}

#gallery img {
    border: 1px solid #ccc;
    padding: 0.4em;
}

#overlay {
    position: absolute;
    top: 0.5em;
    left: 0.5em;
    right: 0.5em;
    bottom: 0.5em;
    background-color: transparent;
    opacity: 0.4;
}

#colors:before {
    content: "Select a color overlay: ";
}

#colors li {
    display: inline-block;
    margin: 0 0.5em 0 0;
    padding: 0.2em 0.5em;
    border: 1px solid #ccc;
    cursor: pointer;
}

Additionally, jQuery is used in the following way:

$('#colors li').hover(
    function(){
        var color = $(this).text();
        $('#overlay').css('background-color',color);
    },
    function(){
        $('#overlay').css('background-color','transparent');
    });
