Can someone tell me if PostScript printers generally use or floating point or fixed point numbers for their calculations? Thanks for any information you can provide. Mark Charney charney@cs.cornell.edu

If I read the info correctly, it is floating point.

Well, according to the printer optimization study on the Adobe file server (essential reading, IMO), anything that goes into the graphics system is floating point, and that putting integers into such commands shows it down (ie. 10 20 moveto is slower than 10.0 20.0 moveto.) However, I am certain that the control entries that take numeric values take integers. So, in answer, I would say that it depends on the operator being used. -- Ian Farquhar Phone : + 61 2 805-9400 Office of Computing Services Fax : + 61 2 805-7433 Macquarie University NSW 2109 Also : + 61 2 805-7420 Australia EMail : ifarqhar@suna.mqcc.mq.oz.au
