Thanks for doing this.

What would be nice is to get a handle on just what PostScript/PDF objects or structures are triggering the generation of the bitmaps. I'd guess it has something to do with transparency layers, but haven't yet delved sufficiently into the PostScript description of these pages to verify this, or pin-point the nature of the problem any more accurately. The more that we can do to isolate the problem, then the easier it will be for Apple to acknowledge it and to quickly produce a robust fix. > Wendy, I'm going to forward a copy of the .pdf separately to you @ > wendy(a)tug.org --- if anyone else wants to see it e-mail me and I'll > do > a mass mailing when I come in to work tomorrow. Wendy has pre-empted you on this. :-) Please let us know if you can discover anything new, from a deeper analysis of the PostScript or PDF coding. > > William Cheers Ross > > -- > William Adams, publishing specialist > ATLIS > www.atlis.com > ----------------------------------------------------- > Please see for list > guidelines, information, and LaTeX/TeX resources. > > > ------------------------------------------------------------------------ Ross Moore ross@maths.mq.edu.au Mathematics Department office: E7A-419 Macquarie University tel: +61 +2 9850 8955 Sydney, Australia fax: +61 +2 9850 8114 ------------------------------------------------------------------------ ----------------------------------------------------- Please see for list guidelines, information, and LaTeX/TeX resources.
