jcelerier hello :)14:44.44 
  I'm trying to transform a color PDF into B&W with ghostscript14:44.52 
  the PDF is made with xelatex and contains images that originate from eps format and png format14:45.13 
  but upon conversion with gs, with -sColorConversionStrategy=Gray14:45.38 
  I find that my png images are of much lower quality14:45.52 
  and look like they've been converted into jpeg14:45.57 
  how to retain the original image quality and just make it grayscale ?14:46.12
