I am trying to use a linux application to convert .pdf files to .tiff for faxing, however, our clients have not been happy with the quality of GhostScript's tiffg4 device.
In the image below, the left side shows a conversion using GhostScript tiffg4 and the right is from an online conversion service. We are unable to see which application is being used to attain that quality.
Note: The output TIFF must be black & white
Ghostscript Code:
gs -sDEVICE=tiffg4 -dNOPAUSE -dBATCH -dPDFFitPage -sPAPERSIZE=letter -g1728x2156 -sOutputFile=testg4.tiff test.pdf
We have tried these GhostScript devices:
- tiffcrle
- tiffg3
- tiffg32d
- tiffg4
- tifflzw
- tiffpack
My question is this--does anyone know which application and/or setting is used to achieve the quality on the right?
