Hello Sergey,

Thanks for using our products.

I have tested the scenario and I am able to reproduce the same problem. For the sake of correction, I have logged it in our issue tracking system as PDFJAVA-19578. We will investigate this issue in details and will keep you updated on the status of a correction.

FYI, you may try using the Direct-to-PDF conversion method of Aspose.Cells for Java which does not require Aspose.Pdf for Java to complete this job. For more related information, please visit Converting to PDF Files
