hello,i use arcpy.mapping to export e map,code like this:
mxdPath = "C:/dev/temp/base.mxd"
mxd = arcpy.mapping.MapDocument(mxdPath)
...load fc from shapefile...
arcpy.MakeFeatureLayer_management(fc,fname)
addLayer = arcpy.mapping.Layer(fname)
arcpy.mapping.AddLayer(df, addLayer)
arcpy.env.extent = arcpy.Extent(XMin=minX,YMin=minY,XMax=maxX,YMax=maxY)
newExtent = df.extent
newExtent.XMin, newExtent.YMin = minX, minY
newExtent.XMax, newExtent.YMax = maxX, maxY
df.extent = newExtent
ExportToPNG(mxd, outputPath,df,
df_export_width=width,
df_export_height=height,
world_file=None,
resolution=dpi)
i publish it as a gpsrvice,to export png
and then i publish another mapservice with the same shape file
when i add both service on the flex,
the basemap use the service publish by mapservice.
the second layer use the gpservice result.
