[Therion] Setting map border framethickness to zero (off)

[Bruce Mutton]

I have just now solved this problem.  The error status must have been some
combination of setting \framethickness to 0mm and the order in which I was
calling layouts, although I cannot pin down why this would be the case.
Anyway, setting \framethickness to 0mm does now remove a frame that was
previously set in my project.

The key to solving the problem as to why \framethickness was not responsive
to a second call was that I was mistaken in my belief as to the order of
layout calls in export commands.

I always assumed the second layout called would be the second layout
processed.  Alas it seems to be the other way around and layouts in export
commands are processed in reverse order.

eg like this:

      export map -projection plan \

      -layout LayoutProcessedLast   \             

      -layout LayoutProcessedFirst   \

     -output ../Output/CavePlan.pdf

 

At least that is what I deduce from the behaviour where there are
conflicting \framethickness statements.

Except I think I have evidence that for some layout content it is the other
way around.

Anyone else have any insights as to the order of layout processing in export
commands?

Good morning

Probably a simple tex question.

 

I often use this code to create a border around an exported map:

code tex-map

  \framethickness=0.5mm

 

>From time to time (in the same compilation run) I insert one exported map
into another using map-image and usually the inserted map should not have a
border.

To date I have always arranged my layouts so that \framethickness is
undefined while the initial map is exported, THEN set to 0.5 mm for the
second map export.

 

It occurred to me that with my project arrangment it would be more
convenient to set the border to 0.5 mm (in a global layout) and THEN reset
it to zero or undefined in a layout specific to only one of the exports.

I have tried these two options:

 

code tex-map

  \framethickness={}

 

code tex-map

  \framethickness=0mm

 

The first causes error (pdftex exit code 1) and the second draws a 0.5 mm
border around both maps.

 

How should I 'turn off' a map border if \framethickness has already been
set?

 

Regards

Bruce
