Calculates Dimensions and Ratio for an Object to fit in a Container

get-object-fit-data.js

const getObjectFitData = (obj, container, cover=true) => {
	let result = {};

	const ratioX = container.width / obj.width;
	const ratioY = container.height / obj.height;
	const ratioFit = cover ? Math.max(ratioX, ratioY) : Math.min(ratioX, ratioY);

	result.ratio = Math.ceil(ratioFit * 100) / 100;
	result.width = Math.ceil(obj.width * result.ratio);
	result.height = Math.ceil(obj.height * result.ratio);

	return result;
