problem PDF example created by skanpage
SUMMARY
PDF created by Skanpage may be malformed, generates error with GhostScript
"-dPDFSTOPONERROR" flag
Using paperless-ngx to import a PDF created by skanpage.x86_64 24.08.3-1.fc41
from paperless error logs:
subprocess.CalledProcessError: Command '['gs', '-dQUIET', '-dSAFER', '-dBATCH',
'-dNOPAUSE', '-dInterpolateControl=-1', '-sDEVICE=jpeggray', '-dFirstPage=1',
'-dLastPage=1', '-r200.000000x200.000000', '-dPDFSTOPONERROR', '-o', '-',
'-sstdout=%stderr', '-dAutoRotatePages=/None', '-f',
'/tmp/ocrmypdf.io.bnzkaw75/origin.pdf']' returned non-zero exit status 1.

gs version 10.03.1
I can run the command manually:
gs -dQUIET -dSAFER -dBATCH -dNOPAUSE -dInterpolateControl=-1 -sDEVICE=jpeggray
-dFirstPage=1 -dLastPage=1 -r300.000000x300.000000 -dPDFSTOPONERROR -o -
-sstdout=%stderr -dAutoRotatePages=/None -f inputfile.pdf > outfile.jpg
Where it will fail, and removing -dPDFSTOPONERROR and the command succeeds
STEPS TO REPRODUCE
1. Scan document with skanpage
If any of this matters: (Epson ES-300W. Scan source: ADF Duplex, scan
mode:color, bit depth 8bit, scan resolution 300, top left x&y 0, bottom right x
215.8, bottom right y 279.4, ADF skew correction (checked), Scan area size:
Letter)
2. Save as PDF, or Export as PDF (same result with both)
3. use GS command to convert the pdf and observe failure: gs -dQUIET -dSAFER
-dBATCH -dNOPAUSE -dInterpolateControl=-1 -sDEVICE=jpeggray -dFirstPage=1
-dLastPage=1 -r300.000000x300.000000 -dPDFSTOPONERROR -o - -sstdout=%stderr
-dAutoRotatePages=/None -f inputfile.pdf > outfile.jpg
4. Remove "-dPDFSTOPONERROR" flag and observe success
OBSERVED RESULT
Failed conversion of pdf created by skanpage
EXPECTED RESULT
successful conversion of pdf created by skanpage
