[OS X Emacs] problems: LaTeX + dvips+ps2pdf

[Roussanka Loukanova]

Dear Win,

After advices from the TeXShop list, in the same Thread, I get

(1) the drawings that require pstricks look finley, by XeLaTeX, in one
typeset run (+ BibTeX + latex, if needed) after having selected:

Aquamacs > Command > Use XeTeX engine
Aquamacs > Command > TeXing Options > Generate PDF
Aquamacs > Command > TeXing Options > DVI and PDF > dvips + ps2pdf

%% for Aquamacs at the end of the tex file for automatic (latex+dvi+ps2pdf)
with XeLaTeX engine
%%% Local Variables:
%%% mode: latex
%%% TeX-engine: xetex
%%% TeX-master: t
%%% End:

(2) but an option for the transparency doesn't go well, by the XeTeX
output, and in the log:
 %%%% WARNING: Transparency operations ignored - need to use
-dALLOWPSTRANSPARENCY

I hope these can be preset in the upgrade of Aquamacs.
