[Therion] Tex-map code for passing variables

[Martin Budaj]

Hi,

I think the following should work:

1) use \loadpicture{\pathvar} in the shared thconfig file
2) define \pathvar macro in the 'code tex-map' section of the
customised thconfig file: \def\pathvar{yourfile.pdf}

The inset map gives an overview/location reference, much the same as the navigation panel in an atlas. The maps share a common layout block in a shared thconfig file. Parameters in the shared layout are populated with map specific information via Therion data and some variables (eg \cavename) that I set in a thconfig file customised for the specific map. I want to keep the common layout generic in case I need to change it in the future and to avoid having to update it in numerous files. What I'm trying to do with \loadpicture is select the picture that is the location overview for the specific map. I can do it using a hardcoded file path but I need it to work with a variable that contains the file path. I would then set the variable in the thconfig for a specific map. The layout command ‘map-image’ doesn't work because I have redefined the \maplayout macro in a tex-map code block.

I’ve tried reusing an existing variable like \the\comment but that only produces a compile error. My Tex knowledge is limited so I am struggling with working out how to set this up. Also, if anyone knows of a better way to achieve the same result I’d be eternally grateful if you would share that knowledge.
