Hi Sujit,
Thanks for your inquiry.
I have tested the scenario again with the input documents, shared over previous thread, while using latest version Aspose.Pdf for .NET 17.6 and noticed that the text overlapping issue was not encountered. It seems that conversion engine for PDF to PNG is much improved in latest release of the API. For your reference, I have also attached an output, generated by using latest version.

Please try using latest release of the API and in case if you still face any issue, please share your input document, so that we can test the scenario in our environment and address it accordingly.
