Is there a way for me to check if the mouse is over a visible part of a PNG image?
Each section is it's own image with a transparent background like:
So basically I want the opacity of each region to be 1 when it is hovered, and the opacity to be 0.5 when not hovering over it. Therefore the user can see which region is being hovered over.
Is there something like onmouseover if mouse position on image != transparent then...
Have a look at http://www.w3schools.com/tags/tag_area.asp
You can take image and you will get cords for each poly by using some image tool like photoshop etc and you can handle each hover event for specific region in area tag for Image.
Simply its easy to use and to make clickable map.
Take specific image in two copy.one before href link and next next href link images..
<script type='text/javascript'>
$(document).ready(function()
{
$(".button").hover(function()
{
$(this).attr("src","button-hover.png");
},
function()
{
$(this).attr("src","button.png");
}
);
}
);
</script>
<body>
<img src="button.png" alt="My button" class="button" />
</body>
</html>
It is programmable in HTML5, without any tools or manually build the <map> <area shape=poly coords="325,25,262,....>
