Annotation trouble within mapscript

[Jean-Denis Giguere]

Hi !

I have trouble with an annotation layer using python mapscript.

This layer is drawn without trouble using mapserv cgi. I have no error
message when I try to draw it with mapscript, but I get no label. The
annotation layer is routesEti. Following the related part of the script
and mapfile.

Any hint would be really appreciated.

Regards,

Jean-Denis

*** Script

#Mapfile
mapfile = "../../mapserv/mapfile/sbk-demo.map"

#La cartographic object
carto = mapscript.mapObj(mapfile)

#Map
carte = carto.prepareImage()

#Layer to draw
aAfficher = []
aAfficher.append("routes")
aAfficher.append("rivieres")
aAfficher.append("batiments")
aAfficher.append("parcs")
aAfficher.append("routesEti")

for nm in aAfficher:
         layer = carto.getLayerByName(nm)
         layer.status = mapscript.MS_ON
         layer.draw(carto, carte)

#Name of map
prefix = "/home/data/www/geodemo/tmp/"
nomCarte = carto.name
nomFichCarte = '%s%s.%s' % (prefix, nomCarte, carto.outputformat.extension)

#Write map
carte.save(nomFichCarte)

#Access file
accesCarte = "/tmp/%s.%s" % (nomCarte, carto.outputformat.extension)
