@Stuart,
I think the problem seems to be that the {indir} in the
[latex-filter-style] section of latex-filter.conf is substituted when
the filter is loaded and so it is the document directory, but the
{indir} in [image-blockmacro] is substituted when that template is
expanded during processing of the included file in a subdirectory and
so is the subdirectory. So the two occurrences of {indir} are not the
same and the image encoding fails.
Really both should use something that is constant {docdir} or similar.
But [image-blockmacro] can't simply be changed as it will break many
existing documents. Similarly delaying substitution in the filter
would allow both commands to use the subdirectory, but would not be
backward compatible and again may break current documents.
I don't have a simple solution that is backward compatible, and I
wonder how many other filters are subject to similar problems?
@Anibal,
As you can see above, it may not be that simple to fix.
One interim "solution" if you can't put everything in one directory,
is to pre-process the latex to png and include the processed result
with image:: macros. The filter command latex2png can be run by
itself, see the filter documentation and latex2png --help for more
info. If the latex was always in its own files (say with a .asclatex
extension) a script could easily process all those files and generate
the png. At a later time the image:: macros could be replaced with
include:: to include the original.
Cheers
Lex
