[NTG-context] PDF grayscale conversion (OT)
I have used to ConTeXt to generate a hefty PDF file with b/w text and color images. Is there a way to convert this file to a PDF file with b/ w text and grayscale images (256 shades)? I know I could always convert the images first and then reset the book, but I was wondering if there was a simpler more direct way before I start doing that. (There are over 70 images.)
