HTMLImageElement: Image() constructor
{{APIRef("HTML DOM")}}
The Image()
constructor creates a new {{DOMxRef("HTMLImageElement")}}
instance. It is functionally
equivalent to {{DOMxRef("Document.createElement()", "document.createElement('img')")}}
.
[!NOTE] This function should not be confused with the CSS
image()
function.
Syntax
new Image()
new Image(width)
new Image(width, height)
Parameters
width
{{optional_inline}}
- : The width of the image (i.e., the value for the
width
attribute).
- : The width of the image (i.e., the value for the
height
{{optional_inline}}
- : The height of the image (i.e., the value for the
height
attribute).
- : The height of the image (i.e., the value for the
Usage note
The entire bitmap is loaded regardless of the sizes specified in the constructor. The
size specified in the constructor is reflected through the properties
{{DOMxRef("HTMLImageElement.width")}}
and {{DOMxRef("HTMLImageElement.height")}}
of the
resulting instance. The intrinsic width and height of the image in CSS pixels are
reflected through the properties {{DOMxRef("HTMLImageElement.naturalWidth")}}
and
{{DOMxRef("HTMLImageElement.naturalHeight")}}
. If no size is specified in the
constructor both pairs of properties have the same values.
Examples
const myImage = new Image(100, 200);
myImage.src = "picture.jpg";
document.body.appendChild(myImage);
This would be the equivalent of defining the following HTML tag inside the
{{HTMLElement("body")}}
:
<img width="100" height="200" src="picture.jpg" />
