Ik heb met ArcPy een aangepaste afdrukservice gemaakt. Deze wordt gehost als GPServer op mijn testserver. De afdrukservice gebruikt een JSON-configuratiebestand om de gegevens uit de mxd op te halen. De JSON die vanuit de webapplicatie wordt doorgegeven, vervangt verschillende tekstelementen. Ik loop echter een beetje vast op hoe ik de legenda kan weergeven met de JSON die vanuit de webkaart wordt doorgegeven. Ik heb in mijn MXD een legenda-element met de naam "Route_Legend".
In dit voorbeeld stuur ik deze JSON naar de afdrukservice

Ik werk meestal met PDF's. Ik heb online onderzoek gedaan, maar kon geen voorbeeld vinden dat een JSON-configuratiebestand gebruikt. Het JSON-configuratiebestand ziet er als volgt uit:
<SPAN class="punctuation token">{</SPAN> <SPAN class="string token">"layer_title"</SPAN><SPAN class="punctuation token">:</SPAN> <SPAN class="string token">"Route_Title"</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"district_fld"</SPAN><SPAN class="punctuation token">:</SPAN> <SPAN class="string token">"District"</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"scenario_fld"</SPAN><SPAN class="punctuation token">:</SPAN> <SPAN class="string token">"Scenario"</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"version_fld"</SPAN><SPAN class="punctuation token">:</SPAN> <SPAN class="string token">"Version"</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"cis_link_id_fld"</SPAN><SPAN class="punctuation token">:</SPAN> <SPAN class="string token">"CISLINKID"</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"map_title_fld"</SPAN><SPAN class="punctuation token">:</SPAN> <SPAN class="string token">"Map_Title"</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"out_flds"</SPAN><SPAN class="punctuation token">:</SPAN> <SPAN class="string token">"District,Scenario,Version,Map_Title,CISLINKID"</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"title_element_text"</SPAN><SPAN class="punctuation token">:</SPAN> <SPAN class="string token">"Routenummer"</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"district_element_text"</SPAN><SPAN class="punctuation token">:</SPAN> <SPAN class="string token">"District"</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"scenario_element_text"</SPAN><SPAN class="punctuation token">:</SPAN> <SPAN class="string token">"Scenario: xyz"</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"version_element_text"</SPAN><SPAN class="punctuation token">:</SPAN> <SPAN class="string token">"Versie: xyz"</SPAN><SPAN class="punctuation token">}</SPAN><SPAN class="line-numbers-rows"><SPAN></SPAN></SPAN>
