I need to get Image height and width before loading the Image itself. So I am using jquery .load() method.
$('<img />').attr('src',someURL).load(function(){
console.log(this.width);
console.log(this.height);
})
But problem is that I need the height according to the fix width. Suppose Image is of size 400*417, I need the height according to 200 not 400. For that I add
$('<img />').attr({
'src':someURL,
'width':200}).load(function(){
//Get height and width
})
But Above code is again giving me height 417 not according to width of 200. I am looking for js/jquery/angualrjs. Please help.
Thanks In Advance :)
A bit of math will do the trick. Once you get the actual image dimensions, apply your ratio to get the height you want.
For instance :
$('<img />').attr('src',someURL).load(function(){
console.log(this.width); // prints out 400
console.log(this.height); // prints out 417
var widthIWant = 200;
var heightIWant = this.height * widthIWant / this.width; // Gives you 208.5
})
