I'm converting some PDFs to binary PNG using NConvert in Linux (CentOS 6.8 x64 / NConvert v6.88 / GS v8.70).
On every run, I get the help from ghostscript in the output (even if -quiet mode is enabled in NConvert... seems that it is not passing -quiet to ghostscript too):
/opt/nconvert/nconvert -quiet -xall -dpi 300 -binary floyd -out png -o 0000-####.png 0000.pdf
where 0000.pdf is a 30 page PDF file
The output looks like this:
Code: Select all
/opt/nconvert/nconvert -quiet -xall -dpi 300 -binary floyd -out png -o 0000-####.png 0000.pdf

My question is: How can I suppress the ghostscript help?
It's bugging me because it's very hard to check the NConvert output.
It should look like this:
