javascript - Getting the size of a resized BG image -


i have div background image, size set contain:

.image{     width: 95%;     height: 95%;     position: absolute;     margin: 0 auto;     left: 0;     right: 0;     top: 50%;     -webkit-transform: translatey(-50%);     background-image: url('image_url');     background-size: contain;     background-repeat: no-repeat;     background-position: center center; }

large images being "scaled down" fit in div. want width , height of image after scaled down background-size: contain;

i tried following:

var myimg, frame; document.addeventlistener("domcontentloaded", onload); function onload() {     myimg= document.getelementbyid('image');     frame = document.getelementbyid('frame');      var img = new image();     img.src = window.getcomputedstyle(myimg).getpropertyvalue("background-image").replace(/url\(|\)$/ig, "");     img.onload = function() {         var imgheight = img.height;         console.log(imgheight);     } }

the problem i'm getting size of actual image, not resized one. can done? also, need use plain vanilla js, not jquery or other library...
