[mapserver-users] Force labels uppercase

[Anton Bakker]

Hi list,

I am trying to set a label to uppercase in my mapfile (example https://i.imgur.com/ExRZhia.png). Seems it is already implemented (https://github.com/mapserver/mapserver/issues/4255), but I cannot figure out how use it.

The comments in the issue seem to hint at an expression element in the label element:

LABEL
  TYPE TRUETYPE
  ALIGN LEFT
  ANGLE AUTO
  ANTIALIAS TRUE
  BUFFER 2
  COLOR 107 107 108
  FONT arial
  MINDISTANCE 200
  MINFEATURESIZE AUTO
  PARTIALS FALSE
  POSITION AUTO
  PRIORITY 10
  SIZE 14
  EXPRESSION (upper("[NAME]")
END

But this did not work for me. Anybody knows how to force labels to appear in uppercase? 

Thanks!

Kind regards,
Anton
