identify fails if called from scanadf script

[pphilw]

I have a script, which is called from scanadf. It converts the scanned pnm to a pdf file, and then calls identify. that call gives the following error:

identify: `%s' (%d) "gs" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pbmraw" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72" "-sOutputFile=/tmp/magick-8406Y34znpxiu1bz-1" "-f/tmp/magick-8406zpxPelFxv1o8" "-f/tmp/magick-8406-d8anTkmZ5BH" @ error/utility.c/SystemCommand/2029.
identify: Postscript delegate failed `001.pnm.pdf': No such file or directory @ error/pdf.c/ReadPDFImage/713.

Calling identify from the command prompt works fine:
identify 001.pnm.pdf
001.pnm.pdf PDF 612x792 612x792+0+0 16-bit Bilevel Gray 61KB 0.010u 0:00.000

just a guess, but your scanadf system probably does not know where Ghostscript is installed

Thanks. But ghostscript is in the "standard" path ( /usr/bin/gs ). Also, the scanadf script inherits the shell environment (I checked by executing "env" from within the script). Any idea how to debug this further?

try renaming with only one period before pdf

001_pnm.pdf

Thanks for the suggestion, but this does not help, either. I created a file test.pdf in my home directory, and the script called from scanadf only executes "identify /home/xxx/test.pdf". Here is the output:

Code: Select all

identify: `%s' (%d) "gs" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pbmraw" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72"  "-sOutputFile=/tmp/magick-5960NKTiA7Oc3RDu-1" "-f/tmp/magick-5960R2HCXd9VsHLI" "-f/tmp/magick-59601zlxWTKBcBTW" @ error/utility.c/SystemCommand/2029.

identify: `%s' (%d) "gs" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pbmraw" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72"  "-sOutputFile=/tmp/magick-59623Lic0cn8loKu-1" "-f/tmp/magick-5962ZjgvOwsa3WOI" "-f/tmp/magick-59624XAor9MIyzTW" @ error/utility.c/SystemCommand/2029.
identify: Postscript delegate failed `/home/xxx/test.pdf': No such file or directory @ error/pdf.c/ReadPDFImage/713.

On the other hand, if I call "identify /home/xxx/test.pdf" from the CLI, I get:

Code: Select all

/home/xxx/test.pdf PDF 612x792 612x792+0+0 16-bit Bilevel Gray 61KB 0.000u 0:00.000

Any other ideas?

[pphilw]

Interestingly, it works if I execute this in my scanadf script like this:

Code: Select all

ssh localhost identify /home/xxx/test.pdf

But this cannot be the "right" solution. I tried to execute it using "bash -c" and "bash -l -c", but none of those work.

Clearly, the "ssh-trick" is not a viable workaround, though.

bump?

Is 001.pnm.pdf actually created by your script?

yes
