PrintTask line not visible (map.graphics layer)

MatejSkerjanc — Mon, 20 Aug 2012 09:20:30 GMT

I'm using printtask to make a print of the map.
I add some graphics to map.graphics layer. In case of point or polygon the print task will actually print the result but if its a polyline the result will be only seen on map itself (as per result of map.graphics.add) but not on the printed image/pdf.
I dont think the symbol is wrong since i use same marker for line and polygon...

pointStyle : new esri.symbol.SimpleMarkerSymbol(esri.symbol.SimpleMarkerSymbol.STYLE_SQUARE, 20, null, new dojo.Color([255,255,0,0.5]));
linepolyStyle : new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol("dashdot", new dojo.Color([255,0,0]), 5), new dojo.Color([255,255,0,0.25]));

pseudo code
if point{
add graphic to map.graphics
}
else //so if polyline or polygon
{
add graphic to map.graphics
}

Hopefully someone already met and solved this issue:)

Can you post the JSON sent from your app to the server? You can pull that out of the request using a tool like Fiddler.

Use a SimpleLineSymbol instead of a SimpleFillSymbol for your line graphic(s).

I was doing this at home and just for kicks tried the base symbol and it worked. So Derek your answer is correct and deserves a tick.
Thank you both.

p.s. i still don't understand why though

Glad you got it figured out.

The reason you need to do this is that you have to use different symbol types for different geometry types. Points require a marker symbol, lines require a line symbol and polygons require a fill symbol.
