I have a latex file (for my free 1300 page physics textbook)
that produces a flip movie, i.e. an image on every page.
I do this in raw postscript. (See part of the code below.)

But if I change one line only, namely from
\includeonly{C-2-CLSA}
to
\includeonly{C-0-INTR,C-2-CLSA}
the pattern disappears. Why?

After all, the pattern is only two commands,
one definition of a macro, and a \special
command. I do not use or redefine the
macro \cscscspage anywhere else.

So why does the pattern disappear?
My guess is that something strange happens with c@page.
I thought this is just the page number.
Any help is appreciated!

Christoph



Code: (works!)

\documentclass{motionmountain}
\includeonly{C-2-CLSA}
\begin{document}
%
\makeatletter%
\def\cscscspage{\the\c@page \space }%
%
\special{!userdict begin
.... some raw pstscript code deleted ...

% 30 means that the counter Pmv is the page number minus 30
/Pmv \cscscspage 30 sub def

.... more raw pstscript code deleted that is inside a bop-hook,
    and based on the counter Pmv
}
\makeatother%

..... Rest of document ....

It would appear you have something in the C-0-INTR file that
breaks the pattern.  Perhaps something to do with pagenumbering.

I found the culprit: it was a \pagecolor{white} command.
That overprints the movie. I have to redesign certain things.
