PDF is incompatible with Linux?
I had cause recently to view tax forms for New York state, available here:
https://www.tax.ny.gov/pit/ads/efile_addit201-2d.htm
Blithely disregarding the statement that "This form is not compatible with Linux operating systems", I downloaded and tried to view both form IT-201 and form IT-2:
https://www.tax.ny.gov/pdf/current_forms/it/it201_fill_in_2d.pdf
https://www.tax.ny.gov/pdf/current_forms/it/it2_fill_in_2d.pdf
Both of these PDFs appear to have some kind of deliberate incompatibility such that when I open them with Evince, they show a yellow screen telling me that the PDF is only compatible with Adobe Reader.
Following the instructions in https://gitlab.gnome.org/GNOME/evince/-/issues/1517#note_960597, I decided to try to render the PDF using Poppler:
pdftocairo -png -f 1 -l 1 nys\ it-2.pdf -o cairo-output
In Evince, although the yellow screen is shown, I can click and drag to highlight text, and what is highlit is the underlying tax form ("... return, enter spouse's name on line below ...").
The form is visible normally and appears to be editable in Firefox, although it won't let me scroll to the second page.
