title: Higher Quality of JFreeChart charts
body: <p>I want to embed a PNG of a chart which I created with JFreeChart into a PDF document. The problem here is, that the quality of the chart is very poor. My goal is to have PNGs with 300 DPI. I googled for almost an hour now but I could not find a solution. </p>
  
  <p>Is there a way to export the generated charts from JFreeCharts as a PNG (or a JPEG) with 300 DPI?</p>
