How to display memory PDF in wxpython

[Larz60+]

To view a pdf file with wx.lib.pdfviewer.viewer.pdfViewer, you use:

   pdfV.viewer.LoadFile(r'a path to a .pdf file')

that works well if the pdf happens to be a file on your computer.
what do you do if the pdf is in memory as the result of a a requests like:

doc = requests.get(url)
if doc.status_code != 404:
   found_pdf = True

If necessary, I'll save it to a temp file, but
I'm hoping there's a method for loading from memory

Does anyone know how this is done?
