How to properly insert an image in PDF with PyMuPDF 1.22.*?

[ipoyt]

Hello!
I have run into a little problem. I need to paste a new image in a PDF file which isn't stored or saved there; I have a base46-string image img:

imgdata = base64.b64decode(img)
im = io.BytesIO(pngdata)

Then I used the guide from PyMuPDF insert image at bottom:

if not page.is_wrapped:
    page.wrap_contents()
page._insert_image(rect, stream=im)

Firstly, there's no insertImage metod available in 1.22.*, I found _insert_image instead.
Secondly, the output is:

return _fitz.Page__insert_image(self, filename, pixmap, stream, imask, clip, overlay, rotate, keep_proportion, oc, width, height, xref, alpha, _imgname, digests)
TypeError: in method 'Page__insert_image', argument 2 of type 'char *'

Do you have any ideas what I am doing wrong?

The image insert method is insert_image.
You normally do not need to convert the binary data output imgdata from base64 via PIL first. That is to say, all image formats complying with https://pymupdf.readthedocs.io/en/latest/pixmap.html#supported-input-image-formats can be used directly as values for parameter stream.
