GeoKernel Electron

Electron bindings for the GeoKernel GIS SDK.

npm install geokernel-electron

const { app } = require("electron");
const { ViewerTool, ViewerWindow } = require("geokernel-electron");

app.whenReady().then(() => {
  const viewer = new ViewerWindow({ title: "HelloMap", width: 1200, height: 800 });
  viewer.setActivationType("Developer");
  viewer.addLayer("D:\\data\\world_4326.shp");
  viewer.setMapStyle("midnight-blue");
  viewer.setTool(ViewerTool.PAN);
  viewer.show();
  viewer.fullExtent();
  viewer.runUntilClosed(() => app.quit());
});

Public API

The package exposes both a convenient ViewerWindow API and the raw native binding layer.

const { ViewerWindow, ShapeType, createNativeLibrary } = require("geokernel-electron");

const viewer = new ViewerWindow({ title: "GeoKernel" });
viewer.addLayerFile("D:\\data\\world_4326.shp", { coordinateSystem: "EPSG:4326" });
viewer.addOpenStreetMapLayer();
viewer.addEmptyVectorLayer("Drawings", ShapeType.POLYGON);
viewer.setLayerVisible(0, true);
viewer.zoomToLayer(0);

const native = createNativeLibrary();
console.log(native.getFunction("GeoKernelViewer_GetLayerCount"));

Coverage

npm run generate:native
npm run coverage
npm run verify:native

npm run coverage compares the Electron bindings with GeoKernel.Viewer/Interop/InteropBridge.h. npm run verify:native loads GeoKernel.Viewer.dll and verifies that every bound export exists.
