调整php功能图像的高度 - wordpress

Hi I'm a bit of a newbie to php. Currently I'm working on a custom pdf invoice but trying to use one image in two different places but need them to be two sizes at the moment my first placing fits well but the other placing needs to be smaller. I'm a little lost in how to achieve this.

<td class="logo-label">
            <table>
                <td class="header">
        <?php
        if( $this->has_header_logo() ) {
            $this->header_logo();
        } else {
            echo $this->get_title(); {
        }
        ?>

The idea height would be 28px (pixels) from the original 48px. I've tried everything but cannot seem to get it to work without it breaking the pdf. Image of what it looks like in pdf form
