naturalHeight and naturalWidth property new or deprecated?

Question

naturalHeight and naturalWidth property of HTMLImageElement object is not mentioned in mozilla website Link

Although both properties works fine in Firefox but i don't see this in documentation.

Is it a deprecated property or new in HTML5?

Can someone give me a link where these properties are defined in standard?

Answer 1

Definitely not deprecated. Checking the HTML5 spec for the img element, we can see:

The IDL attributes naturalWidth and naturalHeight must return the intrinsic width and height of the image, in CSS pixels, if the image is available, or else 0. [CSS]
