[mgp-users 1509] Re: Problem with mgp2ps -c

[David Ronis <ronis@ronispc.chem.mcgill.ca>]

Hi Yoshifumi,

Thanks for the reply.  I tried adding the -sty color and other
directives as you suggested.  Couple of things:

1.  In the usual presentation, the colors seem to be reversed; i.e., the
equations come out in black surrounded by a white background (I'd guess
that it's the boundingbox).

2.  When I run mgp2ps -c things work slightly better:  now the equations
come out in the expected colors, however, only the last equation on the
page displays.  The other ones flash by and are overwritten by any
subsequent latex output.  (I have multiple %filter sections, one for
each equation, even if they're on the same page).

Suggestions?

David
