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

[Win Treese]

Hi, Roussanka.

You can configure AUCTeX to use the extra option with ps2pdf either using the Customize interface or Emacs Lisp.

Customize
———————
1. From the menu: Options->Customize Aquamacs->All Settings Matching…
2. Search for TeX-command-list
3. In the buffer that comes up, search forward for Ps2Pdf
4. In the box with the ps2pdf command, make it say
 
	ps2pdf -dALLOWPSTRANSPARENCY %f

5. Go back up to the top up of buffer and click “Apply” to try it out or “Apply and Save” to keep it for future use.
6. Try it out to make sure it works.

With Emacs Lisp
——————————
In your configuration file, put
(push 
    '("Ps2pdf" "ps2pdf -dALLOWPSTRANSPARENCY %f" TeX-run-ps2pdf nil t :help "Convert PostScript file to PDF”)
    TeX-command-list)
to be run after AUCTeX is loaded.

If you need more detail on either of them, let me know.

Best,

- Win

Because my drawings are large, you can try with the test file by Herbert Schulz, which I included in the above Thread too, together with the content of the problematic .log.
