jQuery에서 크기를 조정하는 동안 이미지 비율을 유지하는 방법은 무엇입니까?

<code class="javascript">/**
 * Conserve aspect ratio of the original region. Useful when shrinking/enlarging
 * images to fit into a certain area.
 *
 * @param {Number} srcWidth width of source image
 * @param {Number} srcHeight height of source image
 * @param {Number} maxWidth maximum available width
 * @param {Number} maxHeight maximum available height
 * @return {Object} { width, height }
 */
function calculateAspectRatioFit(srcWidth, srcHeight, maxWidth, maxHeight) {

    var ratio = Math.min(maxWidth / srcWidth, maxHeight / srcHeight);

    return { width: srcWidth*ratio, height: srcHeight*ratio };
}</code>
