I view charts on my website using the Google Charts API, and I want to export them to a report for users, most likely a PDF file. What methods are available for this programmatically in a PDF file?
Consider using iTextSharp. This is a free open source tool for programmatically creating PDF files from .NET applications.
I recently wrote an article on how to use iTextSharp to export charts generated by Microsoft Chart Controls to PDF: Using Microsoft chart controls in ASP.NET Appendix: Exporting charts .
I was just looking for "png-to-pdf" and there are dozens of solutions out there, some of them free.
