Peculiar thing happened yesterday when I tried to look at a WriteNow file that I put together under OS 1.0. It had a logo in it, an EPS file that I had made using YAP, that was left in a "shown" state, i.e., appeared on-screen as a picture, not a hidden graphic. Under 2.0, however, it opens up with the graphic hidden. And (unlike the situation, say, with NextAnswer misc.457.wn), clicking hide and show graphics in the menu does not bring it up. (It also prints as hidden, of course; WYSIWIG.) Has anyone else seen this problem? Any known cures? To compound the mystery, I tried placing the offending graphic (the file logo.eps) in a NEW WriteNow document, and in this case, all that shows up on the screen is a small dot. Which I cannot expand to a visible size, so I don't KNOW if it is hidden or shown. Is this proper behavior? Further (but smaller) mystery: copying and pasting the graphic from the original document to the new one does not solve anything. Dick Silbar

Your .eps file probably isn't a totally valid; ie, it's missing some required component in the header or the bounding box. Under 1.0, WriteNow parsed .eps files itself; under 2.0, it uses NeXTstep's .eps parser, which is somewhat more sensitive about errors. Your 1.0 WriteNow document knew the image size, so under 2.0 the area the image would've occupied is shown correctly, although the image isn't displayed. When you try to put the image in a new document using 2.0 WriteNow, the file isn't parsed, so WriteNow never even finds out about the bounding box. That explains the mystery of why your original document has some idea of the size of the image and why a new one doesn't. Your .eps file should minimally have something like the following in its header: %!PS-Adobe-2.0 ... possibly other lines starting with %% ... %%BoundingBox: 100 20 600 750 ... Ali, Ali_Ozer@NeXT.com

Right now I'm trying to convert WriteNow .ps files to .eps to import them into an Amiga DTP package that will handle .eps (I don't have a NeXT printer yet) and print them out. I've been told that the only difference is in the header, and if it's a matter of putting the BoundingBox at the beginning, rather than (atend), great. If it's more than that, can you (or anyone else) tell me what it is? Thanks, -drin Adrian Smith ersys!drin@nro.cs.athabascau.ca Edmonton Remote Systems: Serving Northern Alberta since 1982

There's definitely more than just the bounding box thing that you will have to fix. Among other things, certain operators are not allowed in EPS files, which seems like a potential roadblock in your conversion. Eric Ly CSD, Stanford University
