print map with large custom features

yanli — Sun, 12 Dec 2021 16:22:24 GMT

I create 100 polygon features in map,then i print the map with the features,But I run the printTask , the server is collapse; I create 20 polygon the print the result is ok. the number for printTask is limit?

I use the arcgis api for js 3.17!

function ShowByZhen(id) {
 var queryTask = new esri.tasks.QueryTask("http://192.168.20.1:6080/arcgis/rest/services/zhen/MapServer/0");
 var query = new esri.tasks.Query();
 query.returnGeometry = true;
 query.outFields = ["*"];
 query.where = "1=1";
 queryTask.execute(query, ShowByZhen_ShowResults);
 queryTask.on("error", queryTaskErrorHandler);

}

function ShowByZhen_ShowResults(results) {

// var symbol = new esri.symbol.SimpleFillSymbol().setColor(new esri.Color([205, 192, 197,0.5])).outline.setColor(new esri.Color([189, 0, 38, 0.5]));
 var symbol = new esri.symbol.SimpleFillSymbol().setColor(new esri.Color([205, 193, 197, 0.5]));
 var fss = new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID,
 new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_DASHDOT, new esri.Color([205, 192, 197]), 2),
 new esri.Color([255,255,0,0.25]));
 alert(results.features.length);
 var resultCount = results.features.length;
 for(var i=0;i<resultCount;i++)
 {
 var mFeature = results.features;
 var mFeatureAttribute = results.features.attributes;
 mFeatureAttribute["moneyfinish"] = 10000*i;
 
 if (i < 130) {
 mFeature.symbol = fss;
 map.graphics.add(mFeature);
 
 }
 }
}


function Print() {
 var printUrl="http://192.168.20.1:6080/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task"
 printTask = new esri.tasks.PrintTask(printUrl, { async: true });
 params = new esri.tasks.PrintParameters();
 params.map = map;


 //*****print
 var ptemplate = new esri.tasks.PrintTemplate();
 ptemplate.layout = "A3 Landscape";
 // ptemplate.layout = "MAP_ONLY";
 ptemplate.format = "jpg";
 ptemplate.layoutOptions = {
 legendlayers: [],
 scalebarUnit: "Meters",
 titleText: Titletxt
 }
 // use the extent of the webmap in the output PDF
 ptemplate.preserveScale = false;
 params.template = ptemplate;

// params.template = "A3 Landscape";
 printTask.execute(params, printComplete);


}

What do you mean by "server is collapse"? Do you get any error message? Did you check the server logs to determine what the issue is?

you are trying to query a set of polygons --> add the result as graphics on map and then --> print ?????

if this is the steps and the number of polygons causing problem try to set the where clause from the query to the Definition Expression and then try to print.

yes, my steps like this "query a set of polygons --> add the result as graphics on map and then --> print", because the query polygon don't have the attibute fields value,i store the attibute value in other sql server database. so i can't query to the Definition Expression and then try to print According to the attibute fields value.

I get the error when create more than 100 polygon

""Error executing tool.: ERROR 000735: Web Map as JSON: Value is required The value is empty. The value is empty. ERROR 000735: Web Map as JSON: Value is required"

the value is missing

the size of "Web Map as JSON" is limited?

May you have to create a database view between Polygon Table and Attribute Table on database level .This spatial view can be used for publishing.

If the Web Map JSON is too large (> 2000 characters) the request must be a POST request. See the comments by Jian Huang‌ in this post: https://community.esri.com/thread/67868#post355575

1. I find with ff the print request default is "post" method ,so I need't to change the request?

2. when i fire the request directly at the REST endpoint? get the error

No need to change the request type then. Have you evaluated the JSON string? You could Json Parser Online for the job.
