Thanks for your interest in our products.
I am afraid Aspose.Pdf does not support the conversion of Crystal Report files into PDF format because due to some legal complications, we might not be able to accomplish this feature. In order to develop this feature, we need to hack the Crystal Reports file format but SAP has some licensing restrictions: http://www.sap.com/solutions/sapbusinessobjects/sme/reporting/crystalreports/licensing/index.epx which does not permit us to do so. I hope you would understand the circumstances.
In case you have any further query, please feel free to contact. We apologize for your inconvenience.
