Hi list,
I'm working with Mapserver 6.4.0, I publish a WMS with a Raster (tif)
styled with Colorrange and it works with this code:
# Layer start
LAYER
NAME "classes"
TYPE RASTER
OFFSITE 0 0 0 # Ignore the black backgroud color
METADATA
"wms_title" "regions"
"wms_srs" "EPSG:32632"
END
STATUS ON
DATA "/full/path/to/file.tif"
PROCESSING "DITHER=yes"
DUMP true
PROJECTION
"init=epsg:4326"
END
END
CLASS
NAME "classe1"
EXPRESSION ([pixel] >= 0 AND [pixel] < 850)
STYLE
COLORRANGE 0 0 255 0 0 255
DATARANGE 0 850
RANGEITEM "pixel"
END #STYLE
END #end class
...same other classes....
END
# Layer end
Then I tried to add a legend object (over the layer in the mapfile):
LEGEND
STATUS ON
KEYSIZE 100 100
TRANSPARENT ON
LABEL
TYPE TRUETYPE
FONT 'arial'
SIZE 8
COLOR 1 1 1
END
END
And the request
"http://......?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetLegendGraphic&LAYER=classes&Format=image/png";
showed only a list of classes name without images.
Then I read on various post
(http://osgeo-org.1560.x6.nabble.com/Use-of-a-Colortable-td4237911.html)
that I had to add a KEYIMAGE "class4.gif" between EXPRESSION and STYLE.
I tried this but the server retrieved an error: "Premature end of script
headers".
I tried to put different paths, different image's types, to change the
position of the KEYIMAGE, but without an improvement.
Finally, what I'm trying to do is possible with mapserver? And if it is,
which could be the problem of my mapfile?
Thanks
Claudio
