According the (old) manual that I have, "gsave saves only the current Graphics State, pushing a copy of it onto the Graphics State stack". It lists the complete set of Graphics State parameters as: CTM Current Transformation matrix color cp Current Position path the current path clip the current clipping path font the current font dictionary line width line cap line join screen a collection of PostScript objects that define the current halftone screen pattern for grey and colour transfer an executable procedure that maps user grey levels into device grey levels flatness miter-limit dash device an internal data structure that describes the current output device James Ashton

One wonders why stuff like this was left out of the newer manuals. Somewhere I have a crufty old (8 1/2 *11) manual that was the for-runner for the RED book. I guess I'll have to go hunt it down. Thanks Cheers Woody BTW. It looks like I maybe moveing to another site. Due to the CRAPOLA going on with AT&T grabbing systems, (several major Texas systems) it appears that Rpp386 is going to server mode. I have made arrangements to keep an active dial-in line on another system, and a news/mail feed on the current one. Until further notice, continue to use my current address for mail... Cheers Woody P.S. It looks like this is NOT going to interfere with the automated posting, but it really sent me scrambling to find a node so that I could maintain it. Cheers Woody
