Thanks Seth
I'm sure I did try the setText method, but I forgot to mention that in
the post.
Thanks for the tip of convertToString() method.
Using your example I get
LABEL
<label parameters>
TEXT (tostring(([SQKM]),"%.0f")+" km2")
END # LABEL
And the expected label format in my contour layer.
Somehow I must missed something with I tried this in the first place, I
think the parentheses around tostring.
Thanks again!

Hi,
The MapScript API docs are back online - see
https://mapserver.org/mapscript/mapscript-api/stub/mapscript.classObj.html#mapscript.classObj
The setText() method should give you what you need. Example (using
Python):
s = mapscript.classObj(layer)
# other style and label stuff
s.setText('(tostring(([SQKM]),"%.0f")+" km2")')
# check the output using
print(s.convertToString())
When using updateFromString it will replace everything in the classObj
hence the error.

Hi
So I have made a contour plot from a raster. Works nicely.
Then I added labels to give context to the contours. Fine.
Now I want to format the labels.
I have found this post
https://gis.stackexchange.com/questions/350089/round-number-for-label-in-mapserver
suggesting a syntax:
TEXT (tostring(([SQKM]),"%.0f")+" km2")
Nice, but I use mapscript. And I do not understand nor find any
examples
how I could do this with mapscript
I tried with:
s = mapscript.classObj(layer)
<other style and label stuff>
s.updateFromString('TEXT (tostring(([SQKM]),"%.0f")+" km2")')
But I get:
EOFError: loadClass(): Premature End-of-File.
So obviously not correct.
Is there someone who could suggest what could be wrong here or what
else
to look at and try?
