[mapserver-users] LABEL-formatting options

[Fawcett, David (MPCA)]

Stephan, 

Since there isn't a MapServer solution until 6.0, a work around could be a python/php/other language script to populate a new column with a lower precision value.  It wouldn't be that hard to write.

David.

Hi Stephan: This is an increasingly asked question but at the moment I don't have a good solution or workaround, it's just not 
possible at the moment. There's a ticket already filed on the subject and it will be addressed in 6.0.

Are you in a position where you could apply a patch to deal with the problem if one were available?

Steve

Hello mapservers,

we are using MapServer for visualizing shapefiles with double entries
inside.

Mainly this are contour-lines from waterdepth. The double values have
32 decimal places and mapserver tries to render them _all_ along a
contourline.
This does not look nice...

Is there an option to trim the values with a dedicated
mapfile-parameter, e.g. where a prinft-syntax can be used to format the
values?

The shapefiles are generated automatically so adding another column with
trunc()ed or round()ed values is no option.

Are there any options to format label-values/strings? I have not found
anything in the docs.

TIA

        Stephan
