HTMLImageElement: Image() constructor - Web APIs | MDN (original) (raw)

Baseline

Widely available

The **Image()**constructor creates a new HTMLImageElement instance. It is functionally equivalent to 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

The width of the image (i.e., the value for the widthattribute).

height Optional

The height of the image (i.e., the value for the heightattribute).

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 propertiesHTMLImageElement.width and HTMLImageElement.height of the resulting instance. The intrinsic width and height of the image in CSS pixels are reflected through the properties HTMLImageElement.naturalWidth andHTMLImageElement.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:

<img width="100" height="200" src="picture.jpg" />
