We're developing a Charting application. We have an option for our client to print our Chart to PDF file. We have problem with dash lines and grid lines that has width more than 1 pixel. Printing with any application other than doPDF would result the dash line becomes solid line. We are thinking about recommending doPDF as a preferred PDF printing Software for our application, but I think we need to know a little more about why it is working. Only then, we could recommend our client to use doPDF because "it comes with <such and such> technology". Do you have anything in mind what is your key technology that makes this works?
Thanks in advance,
