Various operations on a existing PDF in memory

We need to perform various operations on a existing PDF. For them we are using Aspose pdf. These operations are: certified signature, including custom metadata, mark text with different fonts (PDFNEWNET-39386) and turn PDFA or encrypt the document.

Currently we do with other dll and do it all on the same document without saving open on each operation, but with Aspose we can not or do not know.
Is it possible to do this in memory without saving the document in each operation to keep the changes?

Hi Carlos,

Thanks for contacting support.

You can perform all the required operations on existing PDF file while loading the file in Document object. You may also load the file into Document object and once particular operation is performed, you can save the intermediate output in MemoryStream and then perform further operations. Should you have any further query, please feel free to contact.
