After drawing half of a page, I need to duplicate this shape, to the other half of the page. Is there any (portable, if possible) way to do that ? What about if I knew before I even start drawing the first half that I need to draw the picture twice? I make no assumptions about the picture, and the operators I need to draw it (and I cannot draw it twice, it may be using an "image" command, with data from the current file). Thanks for the suggestions, beforehand sarantos

Doesn't PostScript have a 'rotate' operator ? I'd assume they have a 'mirror' operator, IE, a rotation-through-third-dimension operator, too, from the stuff I've seen. >What about if I knew before I even start drawing the first half >that I need to draw the picture twice? As far as I know, PostScript makes a distinction between the *definition* of an image - as constructed in a buffer - and the *printing* of an image, as executed by 'showpage'. Why not build up an image and call it twice ? >sarantos -- richard -- * "Do not look at my outward shape, but take what is in my hand." * * -- Jalaludin Rumi, 1107-1173 * * ..{amdahl|decwrl|octopus|pyramid|ucbvax}!avsd.UUCP!childers@tycho * * AMPEX Corporation - Audio-Visual Systems Division, R & D *
