Using JasperRunManager.runReportToPdfFile() api

Hi all,

I'm working on exporting jasper report to pdf format using the JasperRunManager.runReportToPdfFile(jasperFileName, paramsMap) api.

Would anyone know if I want to pass the font map information before the report generation, what can I do?

As I know, using JRPdfExporter can do it by calling jrPDfExporter.setParameter(JRExporterParameter.FONT_MAP, fontMap). But due to some reason I can't use this api.

Thanks!
