How to render the color ps as Gray scale ps
Hi I generate the color PS using the color images as given below. I am using the DCTDecode filter so that I can embed the JPEG images to the postscript. Now I get the correct postscript with the color image. If I want to render the postscript as Gray scale,what additional changes I need to do? I tried with ProcessColorModel but no success.
Thanks in advance.
