Converting base64 string to PDF in memory

[malkishtini at gmail.com]

 Hello $list,

I have a project to convert a base64 string (which I get from an external REST API) to a PDF and display in a JS form without saving any file to a disk (i.e., convert it to a PDF in memory and display it in an HTML object in the JS form (Studio 8.1.7)).
I have not done this before, so the first thing I thought about was to post a question to the list to see if anyone has done something similar before and could kindly share some ideas with me. 

Thank you in advance for any hints/thoughts.

Best regards,
Mayada
