Hi,
Having trouble with printtask and the export web map tool in Javascript API (legacy)
A user selects values from drop downs, then, a function calls a feature service with a unique values based on the field selected.
ct = new esri.layers.FeatureLayer("http://gis-server.cc.wmich.edu/harcgis/rest/services/hdream/bothcounties_psrazero/MapServer/0",{ mode: esri.layers.FeatureLayer.MODE_ONDEMAND, opacity: .7, outFields: ["*"], //and
var renderer = new esri.renderer.SimpleRenderer(new esri.symbol.SimpleFillSymbol().setOutline(new esri.symbol.SimpleLineSymbol().setWidth(0.5))); renderer.setColorInfo({ field: field, minDataValue: 0, maxDataValue: maxval, colors: [ new esri.Color([255, 255, 255]), new esri.Color([0, 42, 255]) ] }); ct.setRenderer(renderer); map.addLayer(ct); map.reorderLayer(ct,4);
Variable maxval is decided by user.
Then the print task:
function print() { var printUrl = "http://gis-server.cc.wmich.edu/harcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task"; var printTask = new esri.tasks.PrintTask(printUrl); var params = new esri.tasks.PrintParameters(); var template = new esri.tasks.PrintTemplate(); params.map = map; template.exportOptions = { width: 1000, height: 800, dpi: 96 }; template.layout = "MAP_ONLY"; template.preserveScale = false; template.format = "jpg"; template.showAttribution= "true"; params.template = template; printTask.execute(params); dojo.connect(printTask,'onComplete',function(result){ window.open(result.url); }) }
Printing works just fine for other layers, but when the layer ct is added, it appears as a gray box instead of multi -colored choropleth layer.
Is it because the renderer is client-side? How might I get around that so the user can have the choropleth map in the printout?
thanks
