title: HiQPdf not displaying Charts on the generated PDF
body: <p>I have been using the (free version) HiQPdf libraries to converto html pages to pdf documents. </p>
  
  <p>I am also using in my pages several Chart objecs from the .Net Framework (System.Web.UI.DataVisualization.Charting.Chart) to produce bar graphics dysplaying values changing along time. It works wonders in my local environment when I debug with VS, but when I publish on my IIS or on other servers the charts do not appear at all on the pdf - note: they do appear on the webpages just not on the pdf. </p>
  
  <p>In the Pdfs all the html is displayed correctly, inlcuding css, showing it exactly as seen on the page, except the chart images. I kind of understand that they would not appear as in the html, the image source from the charts results in something like:</p>
  
  <pre><code>&lt;img id="MainContent_MyPageControl_ctl00" src="/MyTestWebSite/ChartImg.axd?i=charts_0/chart_0_2.png&amp;amp;g=396d61e14ceb41c08be06fd956cd4dca"
  </code></pre>
  
  <p>Because the real generated png image is not even directly referenced as usual. But the fact is they do appear on the generated pdf when running local from VS, which produces a similar html anyway as the above.
  Only difference I see is that when I run local the Image Chart Handler key is defined in the webconfig as:</p>
  
  <pre><code>add key="ChartImageHandler" value="storage=file;timeout=20;dir=c:\TempImageFiles\;" 
  </code></pre>
  
  <p>but when publishing on a server I have changed it to:</p>
  
  <pre><code>add key="ChartImageHandler" value="storage=file;timeout=20;Url=~/MyfolderTempcharts/;deleteAfterServicing=false;" 
  </code></pre>
  
  <p>So why dont the charts appear too on my generated pdf, or why they do appear if Im running from VS?</p>
  
  <p>Anyone ever had this problem?</p>
