[asterisk-users] SendFAX - multi-page TIFF

[Gabriel Ortiz Lour]

I am using this command to generate the TIFF from a PDF:

/usr/bin/gs -q -sDEVICE=tiffg3 -sPAPERSIZE=a4 -r204x196 -dNOPAUSE
-sOutputFile=$tiffFile -- $pdfFile

And tiffinfo for a 2 page generate file gives:

# tiffinfo teste.tiff
TIFF Directory at offset 0x8 (8)
  Subfile Type: multi-page document (2 = 0x2)
  Image Width: 1728 Image Length: 2292

I think this is correct, since it came from asterisk FAXing Howtos. Is that
correct?
I'll try doing some more tests with debug info ON and post back the results.

Thanks,
Gabriel
