rasterRenderers

A convenience module for importing renderer classes that can be used to render ImageryLayer when developing with TypeScript. For example, rather than importing renderers one at a time like this:

import FlowRenderer from "@arcgis/core/renderers/FlowRenderer.js";
import ClassBreaksRenderer from "@arcgis/core/renderers/ClassBreaksRenderer.js";
import UniqueValueRenderer from "@arcgis/core/renderers/UniqueValueRenderer.js";
import RasterStretchRenderer from "@arcgis/core/renderers/RasterStretchRenderer.js";
import RasterColormapRenderer from "@arcgis/core/renderers/RasterColormapRenderer.js";
import RasterShadedReliefRenderer from "@arcgis/core/renderers/RasterShadedReliefRenderer.js";
import VectorFieldRenderer from "@arcgis/core/renderers/VectorFieldRenderer.js";

You can use this module to import them on a single line:

import { FlowRenderer, ClassBreaksRenderer, UniqueValueRenderer, RasterColormapRenderer, RasterStretchRenderer, RasterShadedReliefRenderer, VectorFieldRenderer } from "@arcgis/core/rasterRenderers.js";

This module also allows you to implement type guards on renderers, making your code smarter.

import { Renderer } from "@arcgis/core/rasterRenderers.js";

function logRenderer(renderer: RasterStretchRenderer): void {
 if (renderer.type == "raster-stretch") {
   // the compiler knows the renderer must be a RasterStretchRenderer
   console.log("renderer color ramp: ", renderer.colorRamp);
 }
}
