[Mapserver-users] Reference image and extent syntax for on-the-fly configuration

[Marcelle Caturia]

What is the syntax for on-the-fly configuration of the reference image and
reference extent?  I'd like to specify the reference image name and extent
using a point-in-polygon query URL, and have unsucessfully tried using the
following code...

LAYER # start of zoom to watersheds layer
  NAME zoom_to_wshd
  TYPE polygon
  STATUS default
  DATA zoom_to_wshd.shp
  CLASS
    COLOR 90 0 80
    OUTLINECOLOR 90 0 80
    SYMBOL 7
    TEMPLATE
"http://[host]/cgi-bin/mapserv36?map=/data/projects/minnesota/View2/View2.m
ap&title=[EPANAME]&layer=majwshd&map_shapepath=/data/projects/minnesotadata/
View2_final/[ABBREV]&mapext=[minx_left]+[miny_btm]+[maxx_right]+[maxy_top]&i
mgext=[minx_left]+[miny_btm]+[maxx_right]+[maxy_top]&entirewshd=[minx_left]+
[miny_btm]+[maxx_right]+[maxy_top]&map_reference_image=/data/projects/minnes
ota/graphics/ref_maps/[ref_name]&map_reference_extent=[minx_left]+[miny_btm]
+[maxx_right]+[maxy_top]"
  END
END # end of zoom to watersheds layer

Any suggestions would be much appreciated.

Thanks,
