How to Maintain Image Proportions During Resizing in jQuery?

Maintaining Image Proportions During Resizing

Maintaining image proportions during resizing ensures that the original aspect ratio is preserved. This is important to prevent distortions and maintain the intended visual impact of the image. In jQuery, this can be achieved using various techniques.

One technique involves using the calculateAspectRatioFit function, which accepts the dimensions of the original image and the maximum allowed width and height. The function calculates the new width and height while preserving the aspect ratio. These calculated values can then be used to resize the image accordingly.

The code for this function is provided below:

<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>

By utilizing this function, developers can resize images while ensuring that their proportions remain intact, providing a consistent and undistorted visual experience across various display sizes.
