¿Reglas de renderizado de Raster Function para aplicar un color ramp?

Question

¿Alguien tiene un ejemplo funcional usando ESRI Leaflet para asignar un color ramp a un DEM alojado como un ArcGIS REST ImageServer? <\/P> <\/P> He estado usando esta documentación de <\/SPAN>ESRI<\/A> <\/SPAN>y he logrado hacer funcionar un ejemplo de hillshade:<\/P> <\/P> \/\/\/Hillshade DEM
var renderingRule = {
"rasterFunction":"Hillshade",
"rasterFunctionArguments": {
"Azimuth":315,
"Altitude":45,
"ZFactor":1
},"variableName":"DEM"
};

var dem = L.esri.imageMapLayer({
url: 'https:\/\/gis.arkansas.gov\/arcgis\/rest\/services\/ImageServices\/DEM_1M_2018\/ImageServer',
renderingRule: renderingRule
});<\/CODE><\/PRE>
<\/P>
Pero no he tenido suerte aplicando un color ramp:<\/P>
<\/P>

var renderingRuleTwo = { "rasterFunction" : "Colormap", "rasterFunctionArguments" : { "ColorrampName" : "Blue Bright" }, "variableName" : "Raster"};var demTwo = L.esri.imageMapLayer({ url: 'https:\/\/gis.arkansas.gov\/arcgis\/rest\/services\/ImageServices\/DEM_1M_2018\/ImageServer', renderingRule: renderingRuleTwo});<\/CODE><\/PRE> <\/P>¡Gracias de antemano a quien pueda brindar alguna orientación!<\/P> <\/P>Edición: Formateo<\/P>

in esri leaflet we're not doing anything special. we just pass through whatever JSON you supply.

if this thread isn't helpful, I'd recommend figuring out the appropriate syntax for your raster function directly at the REST endpoint and asking for help from image service experts if necessary.
