	Here's the scoop.  I have a program that generates Fourier transform 
patterns and save them as files of characters.  The ACSII value of the  
character corresponds to the pixel intensity in the image.  I have two 
questions.  First, how can I convert these files to grey-scale images and 
second how do send graphics output to the laser printer.  I need to do all 
this in TP6.  
	I was able to convert the files to color images using the PutPixel
procedure by assigning the color to the ASCII value of the character, but I 
found nothing in the documentation about grey-scale images or sending 
graphics output to a printer.
	Another option would be to create a TIFF, GIF, or PCX file which 
could be printed with a word processor but I found no information about this
either.  I will be very appreciative of any replies or postings relating to
this problem.  Thank you in advance.
