Resize by height

Asynchronously resizes an image to a specified height.

This feature resizes also the width of the image proportionally, without distorting it.

Syntax​

resizeByHeight(image, heightPx)

Parameters​

  • image : HTMLImageElement
    The image element to resize.

  • heightPx : number
    The new height, in pixels, to resize the image to.

Return​

  • Promise : Promise<HTMLImageElement>
    A promise that resolves with the resized image element.

Throws​

  • Error
    Thrown if the specified height is negative or if there are errors during the resizing process.

Examples​

const editpix = new EditPix();

// image url
const url = "images/img.jpg";

// create image
var image = new Image();
image.src = url;

//waiting image load
image.onload = () => {
    // resize image by height
    editpix.resizeByHeight(image, 100)
        .then(resizedImage => {
            // render modified image
            document.body.appendChild(resizedImage)
        })
        .catch(error => { console.log(error) })
};
