title: screenshot in php
body: <p>I am using google visualization api for my php-based website. I am planning to use tcpdf to give a pdf version of the same images that i am generating using Google Visualization API.</p>
  
  <p>is there any way to save these visualizations on my server so that i use them directly in the tcpdf?</p>
  
  <p>If not then can i automatically take screenshots of the images and use them in tcpdf?</p>
  
  <p>The reason why i am not manually taking screenshots and saving is that, all the values in the visualizations  are dynamic and keep changing every day, so I am working on something automatic. Suggestions please?</p>
