LuaTeX 1.10.0 cannot embed properly PDFs with 4-bit images
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... (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. Best regards, Leonardo -- Leonardo E. Segovia https://www.amyspark.me

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 Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
Ghostscript as well, it's what I've been using to process my own invoices. Best regards, Leonardo On 04/12/2019 09:23, Hans Hagen wrote:

if you remove the encryption (which of course is also illegal) then the document can be included
