Blurry charts with abcpdf

Question

I'm trying to export an HTML page to PDF with ABCpdf. The text converts OK but the charts are very blurry. I've tried increasing the font size and it helps very little. What could be the solution?

EDIT: I'm using the asp.net charts if that helps.

Answer 1

You'll need to output the charts at a higher DPI. Not sure if you can do this with abcpdf though.
