+### AbortController Support
+
+Geotiff.js supports the use of [`AbortController`s](https://developer.mozilla.org/en-US/docs/Web/API/AbortController). Calls to `getRasters`, `readRGB` and `getTileOrStrip` will throw an `Error` with name `AbortSignal` similar to the browser's `fetch` behavior.
+
+```javascript
+const abortController = new AbortController();
+const { signal } = abortController;
+abortController.abort();
+try {
+  const data = await tiff.readRasters({ signal });
+} catch(e) {
+  if (err.name === 'AbortError') {
+    // do stuff
+  }
+}
+```
