Any Idea how to zoom in a image on particular point using javascript, css ? I am using webkit based browser.
I can zoom by specifying zoom property , like `elem.style.zoom="150%", Main problem is I cannot center the image where I want to zoom. I can get the point where I want to zoom using mouseclick.
As I said in my comment above, I would avoid the zoom css property and stick to just javascript. I managed to throw together the following code which works pretty well for the first click, really all it needs is a little more dynamically (even a word?).
<html>
<head>
<script type="text/javascript">
function resizeImg (img)
{
var resize = 150; // resize amount in percentage
var origH = 200; // original image height
var origW = 200; // original image width
var mouseX = event.x;
var mouseY = event.y;
var newH = origH * (resize / 100) + "px";
var newW = origW * (resize / 100) + "px";
// Set the new width and height
img.style.height = newH;
img.style.width = newW;
var c = img.parentNode;
// Work out the new center
c.scrollLeft = (mouseX * (resize / 100)) - (newW / 2) / 2;
c.scrollTop = (mouseY * (resize / 100)) - (newH / 2) / 2;
}
</script>
<style type="text/css">
#Container {
position:relative;
width:200px;
height:200px;
overflow:hidden;
}
</style>
</head>
<body>
<div id="Container">
<img alt="Click to zoom" onclick="resizeImg(this)"
src="https://picsum.photos/200" />
</div>
</body>
