title: tiJsPdf corrupt file but fine on iPhone
body: <p>I am using ti.jspdf to create a stock order form. When adding an image i use</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>PDF.addImage(Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, 'logo/logo-pdf.jpg').nativePath,'JPEG',10,13,60,14);
      </code></pre>
  </div>
  </div>
  </p>
  
  <p>this works fine until i try to open the pdf on anything other than an iPhone.</p>
  
  <p>if i take out the image the pdf opens fine on everything.  I have tried to base64 it as a large string but the port of jspdf to ti.jspdf seems to only support a file path being passed through to it.</p>
  
  <p>has anyone seen / overcome this issue?</p>
  
  <p>Thanks</p>
