Ghostscript as well, it's what I've been using to process my own invoices.

Hello,
I would like to report that since TeX Live 2019, LuaTeX is unable to
embed properly a certain type of image I have.
These sort of images are embedded in the PDFs generated by the tool
"Comprobantes en línea" of Argentina's IRS (Administración Federal de
Ingresos Públicos, https://www.afip.gob.ar).
This is an example:
https://comunadealvear.gob.ar/wp-content/uploads/2017/03/30710518803_01_0002_00000009.pdf
(or just search online for the string "Esta Administración Federal no
se responsabiliza por los datos ingresados en el detalle de la
operación").
Embed this file using the following snippet:
\documentclass{article}
\usepackage{luatex85}
\usepackage{incgraph}
\begin{document}
\incgraph{30710518803_01_0002_00000009.pdf}
\end{document}
Where the white-and-grey AFIP logo appears in the original, LuaTeX
instead embeds a grey-on-grey image, probably by messing with the
alpha channel.
I have consistently reproduced this on every update since the 2019
release. XeLaTeX and pdfTeX do not have this issue.
Please let me know if I can be of more assistance. I hope I've posted
to the right mailing list.
Either remove the encryption or set the flags so that content might be
extracted.
acrobat shows no permissions other than printing ... so basically pdftex
and xetex are violating this; qpdf shows
R = 3
P = -1852
User password =
extract for accessibility: not allowed
extract for any purpose: not allowed
print low resolution: allowed
print high resolution: allowed
modify document assembly: not allowed
modify forms: not allowed
modify annotations: not allowed
modify other: not allowed
modify anything: not allowed
if you remove the encryption (which of course is also illegal) then the
document can be included
