I am trying to put together a very basic sandbox app to load data from a public ArcGIS Server MapService using the Javascript 3.5 API.
However I keep getting the a 400 return status with the error "Output format not supported"
The code is as follows:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no">
<title>Simple Image Service</title>
<link rel="stylesheet" href="https://js.arcgis.com/3.25/esri/css/esri.css" />
<style>
html, body, #map { height: 100%; width: 100%; margin: 0; padding: 0; }
</style>
<script src="https://js.arcgis.com/3.25/"></script>
<script>
var map;
require([
"esri/map", "esri/layers/ArcGISImageServiceLayer",
"esri/layers/ImageServiceParameters", "dojo/parser", "dojo/domReady!"
], function(
Map, ArcGISImageServiceLayer,
ImageServiceParameters, parser
) {
parser.parse();
map = new Map("map", {
basemap: "topo",
center: [-79.40, 43.64],
zoom: 12
});
var params = new ImageServiceParameters();
params.noData = 0;
var imageServiceLayer = new ArcGISImageServiceLayer("https://clientsServer/arcgis/rest/services/TEST/MyMapService/MapServer", {
imageServiceParameters: params,
opacity: 0.75
});
map.addLayer(imageServiceLayer);
});
</script>
</head>
<body>
<div id="map"> </div>
</body>
</html>
Here is a screen shot of the Network tab in the dev tools enter image description here
I tried using the following but they also didn't display (I'm not sure what they mean, just found then in another post)
- https://clientsServer/arcgis/rest/services/TEST/MyMapService/MapServer/export https://clientsServer/arcgis/rest/services/TEST/MyMapService/MapServer/tile
Most simple sandbox app ever, and already scratching my head.... :o(
Any help greatefully recieved

The problem is that you are trying to create an ArcGISImageServiceLayer layer based on a map service REST end point AND feeding ImageServiceParameters. The server then expects that this would be a map service with the imagery support, however, most likely yours is not one.
Most likely, you would need to use the ArcGISDynamicMapServiceLayer instead.

Hi Alex, Yup you were right. Changed code to as follows: urlUtils.addProxyRule({ urlPrefix: "gis.subsea7.com/arcgis/rest/services", proxyUrl: "localhost/ESRI-Proxy/proxy.ashx" }); ArcGISDynamicMapServiceLayer("clientsServer/arcgis/rest/services/TEST/MyMapService/MapServer", { "opacity" : 0.5, "imageParameters" : imageParameters }); Used the ESRI proxy at : github.com/Esri/resource-proxy/tree/master/DotNet so clients server is not setup for CORS. Many thanks for the help!KieronFlynn– KieronFlynn2018年09月17日 14:05:56 +00:00Commented Sep 17, 2018 at 14:05

No worries, glad it worked out well. I can recommend keeping the REST API help page handy as you will likely spend some time there developers.arcgis.com/rest/services-reference/map-service.htm. Also, since you are exploring the ArcGIS Server REST API, I also suggest installing Postman and poking around submitting some requests and seeing what you can get back, super helpful app.Alex Tereshenkov– Alex Tereshenkov2018年09月17日 14:21:44 +00:00Commented Sep 17, 2018 at 14:21
