I need a PDF (vector) to grayscale conversion in Linux CLI.
Any open source tool to achieve that task?
I have already tried ghostscript for that task grayscale conversion was happen but fonts are converted to a rectangle box with a cross mark in adobe illustrator. Any solution for that issue?
- gs -sDEVICE=pdfwrite -sProcessColorModel=DeviceGray -sColorConversionStrategy=Gray -dEmbedAllFonts=true -dPDFSETTINGS=/prepress -o out.pdf -f in.pdf
