Luigi, Yue—many thanks. I will look into with both Ghostscript and ImageMagick to see what I can do. Best, Alan On Mar 10, 2009, at 02;14,12 , luigi scarso wrote:

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.) Maybe with ghostscript
