Many are aware that IE8 does not support CMYK JPG images, as it fails to render them at all.
This post discusses the issue further: , among others.
My inquiry is as follows: Is there a method to detect from JavaScript, akin to Modernizr, whether a browser can display CMYK JPG images?
I could implement a workaround in my JavaScript code to switch to using RGB images for IE8, but I prefer a more reliable solution.
Thank you,
Here is an example using jQuery to detect the browser version:
if ($.browser.msie && parseInt($.browser.version, 10) <= 8) {
alert('IE8 or below');
} else {
alert('Non IE8');
}
Additionally, you can use conditional comments in HTML to target specific versions of Internet Explorer:
<!--[if IE 8]>
<script type="text/javascript">
ie = 8;
</script>
<![endif]-->
For testing CMYK support in browsers, you can try the following JavaScript code:
<html>
<head>
<script>
var IS_CMYK_SUPPORTED = (function(){
var value = 'cmyk(1%,1%,1%,0.5%)',
el = document.createElement('p'),
result = false;
try {
el.style.color = value;
result = /^cmyk/.test(el.style.color);
} catch(e) { }
el = null;
return result;
})();
</script>
</head>
<body onLoad='alert("IS CMYK Supported:" + IS_CMYK_SUPPORTED)'>
</body>
</html>
