将 Html 转换为带图片的 pdf

Question

我正在尝试将 HTML 转换为 PDF，所以我使用了 TCPDF 的 PHP 插件。那是它的官方网站 TCPDF

它运行良好，但它的工具非常有限，字体也有限

它无法将图像转换为 PDF，所以我如何将包含图像的完整 HTML 页面转换为 PDF 文件，无论是 JS 还是 PHP 插件，我只想要有效的解决方案将带有 Css 的整个 HTML 页面转换为 PDF 文件，也许我会保存或打印它

      <h3>SEA MINK</h3>
      <p>The sea mink (Neovison macrodon) was a mammal from the eastern coast
      of North America, in the family of weasels and otters in the order Carnivora.
      The largest of the minks, it was hunted to extinction by fur traders before 1903,
      when it was first given a species description. Some biologists classify it as a subspecies of the
      American mink. Estimates of its size are speculative, based largely on skull fragments recovered 
      from Native American shell middens, and on tooth remains. Some information on its appearance and 
      habits was provided by fur traders and Native Americans. It may have been similar in behavior to
      the American mink: it probably maintained home ranges, was polygynandrous, and had a similar diet, 
      supplemented by saltwater prey. Sea minks were commonly trapped along the coast of the Bay of
      Fundy in the Gulf of Maine. Remains have been found along the New England coast, and there were r
      egular reports of unusually large mink furs, probably sea mink, being collected from Nova Scotia</p>
