https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/how-to-print-raster-layer-with-client-side-pixel/m-p/1177158#M77466 <P>I have a custom widget in WAB that lets the user display filtered elevation data from an image service. It uses client-side pixel filtering as this sample does.<BR /><A href="https://developers.arcgis.com/javascript/3/jssamples/layers_raster.html" target="_blank">https://developers.arcgis.com/javascript/3/jssamples/layers_raster.html</A></P><P>My users complains that they can't print the filtered elevation data, we're using our own print service with custom layouts. So the client-side pixel filtering info is not sent to the print service and the print includes the entire rasterdata displayed as how the image service was published.</P><P>If I add the image service to the map viewer in portal I can change the "symbology" of the raster to use some classification. And then print (with the same printservice as in WAB) and the classified raster displays correctly in the print.</P><P>So I'm thinking I should be able to "convert" the pixel-filtering to a classification with just two classes where one is transparent/invisible. But I haven't been able to set a renderer to my raster layer in my code.</P><P>There seems to be a .setRenderer()-function on the layer, but in the API reference it's only documented for featureLayers and not for RasterLayers. Any ideas how I can solve this?</P> Wed, 25 May 2022 11:21:50 GMT MattiasEkström 2022-05-25T11:21:50Z https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/how-to-print-raster-layer-with-client-side-pixel/m-p/1177158#M77466 <P>I have a custom widget in WAB that lets the user display filtered elevation data from an image service.
