Hi Steve:
You can define a class for every one of the intervals. You can also
build a key image in advance, which will be used for buildng a legend
for a GetLegendGraphic request (currently, a gradient key image will
not be built by mapserver). In the example below each key image
contains gradient for the COLORRANGE values:
=========================
CLASS
NAME "[-255..-200]"
EXPRESSION ([pixel] <=-200)
KEYIMAGE "class1.gif"
STYLE
COLORRANGE 64 0 0 128 0 0
DATARANGE -255 -200
OUTLINECOLOR 0 0 0
END
END
CLASS
NAME "[-200..-175]"
EXPRESSION ([pixel] >-255 AND [pixel] <=-175)
KEYIMAGE "class2.gif"
STYLE
COLORRANGE 128 0 0 192 64 0
DATARANGE -255 -175
OUTLINECOLOR 0 0 0
END
END
CLASS
NAME "[-175..-100]"
EXPRESSION ([pixel] >=-175 AND [pixel] <=-100)
KEYIMAGE "class3.gif"
STYLE
COLORRANGE 192 64 0 255 150 0
DATARANGE -175 -100
OUTLINECOLOR 0 0 0
END
END
CLASS
NAME "[-100..-50]"
EXPRESSION ([pixel] >=-100 AND [pixel] <=-50)
KEYIMAGE "class4.gif"
STYLE
COLORRANGE 255 150 0 240 240 10
DATARANGE -100 -50
OUTLINECOLOR 0 0 0
END
END
========================
