Hello,
We are trying to implement functionality in our application to use a headless browser to generate charts which can be emailed to users. I followed your suggestions in your server side docs for getPdfRenderer(). Below is the relevant code returning a byteArrayOutputStream that we can then insert into our Database and email out on a schedule.
However, the resulting PDF is very blurry compared to the PDF produced using your native exportContent method. Do you have any idea why? I've attached two images showing the difference.

Code:
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
Map<String,String> settings = new HashMap<String,String>();
settings.put("skinName", exportData.get("skinName").toString());
PdfExport export = new PdfExport();
ITextRenderer renderer = export.getPdfRenderer(exportData.get("chartHTML").toString(),settings);
renderer.createPDF(byteArrayOutputStream);
return byteArrayOutputStream.toByteArray();
