This has sort of been touched on in some other postings, but for path reasons I would like to avoid using a shell script and just use ImageMagick's (IM) convert command line executable directly from a \immediate\write18{...}
in a macro command, but in my IM convert instructions I need to pass the %
(ASCII 37) as part of a macro.
However I try to conceive of making a %
- and I have tried numerous ways(!) I always end up getting the Latex code I am using for the % passed through to the command line.
The obvious one, \%
goes to the shell as \%
directly and that is the pattern followed by all other options.
What I obviously seem to need is some way to generate the ASCII or unicode for %
and get that to the shell from LaTeX via \write18
or other.
Or have some sort of temporary suspension on the LaTeX usage of %
so that it can be part of a \write18{}
and not break the command as a comment starter, and so be passed with out needing to be LaTeX escaped first.
\makeatletter \immediate\write18{...\@percentchar ..}
?#
? I have tried\@sharpchar
but it does not exists.
