How to convert PDF to XOD in memory

We have our source files encrypted. The unencrypted version needs to be in memory only.

How do I generate a XOD from this in memory PDF file?

The following code shows how to do in memory PDF to XOD. Note the code below reads and writes to disk, but that is just for testing/demo purposes.

// Debug: load bytes into memory
var pdfBytes = File.ReadAllBytes(pathToPdf);
// disable PDFNet disk caching, so caching is done in memory instead
// create in memory PDF
var pdfDocument = new PDFDoc(pdfBytes, pdfBytes.Length);
// convert to xod
var xodOptions = new pdftron.PDF.Convert.XODOutputOptions();
var filter = pdftron.PDF.Convert.ToXod(pdfDocument, xodOptions);
var filterReader = new FilterReader(filter);
var xodStream = new MemoryStream();
var buffer = new byte[81920];
var returned = filterReader.Read(buffer);
while (returned > 0)
	xodStream.Write(buffer, 0, returned);
	returned = filterReader.Read(buffer);
xodStream.Seek(0, SeekOrigin.Begin);
// Debug: write to disk
var fs = File.Create(outPutPath);
