-- **None** — Do not extract or return any text or layout data. Use this option to minimize memory usage when textual information is not required.
-- **TextOnly** — Return plain text only; layout and bounds are omitted. Note: using `TextOnly` may disable some viewer text features such as synchronous `findText`; use `findTextAsync` when asynchronous search is required.
+- **None** — Do not extract or return any text or layout data. Use this option to minimize memory usage when textual information is not required.

 # Get page info in React PDF Viewer
 
-The `getPageInfo()` method returns metadata for a specified page in the viewer, such as `height`, `width`, and `rotation`. `pageIndex` is zero-based. Call `getPageInfo()` after the viewer is ready to ensure page data is available (for example, in `ngAfterViewInit` or after the document has been loaded).
+### Overview
+
+The `getPageInfo()` method returns metadata for a specified page in the React PDF Viewer, such as `height`, `width`, and `rotation`. Use it when you need to read the rendered size or orientation of a page, for example to align overlays, custom toolbars, or to validate the loaded document.
+
+**Parameter**
+
+| Parameter | Type | Description |
+| --- | --- | --- |
+| `pageIndex` | `number` | Zero-based index of the page. Must be in the range `0` to `pageCount - 1`. Passing an index outside this range returns `undefined`. |
+
+**Return value**
+
+The method returns a `PageInfo` object with the following fields:
+
+| Property | Type | Description |
+| --- | --- | --- |
+| `height` | `number` | Page height in points (1 point = 1/72 inch). |
+| `width` | `number` | Page width in points. |
+| `rotation` | `number` | Page rotation in degrees. Valid values are `0`, `90`, `180`, and `270`. |
+
+Call `getPageInfo()` only after the document has finished loading (for example, inside the `documentLoaded` event handler) to ensure page data is available. Calling it before the document is loaded returns `undefined`.
+
+### How to retrieve page info
 
 The following example retrieves and logs the page dimensions and rotation for a specified page.

-**Step 2:** The following code snippet implements retrieval of height, width, and rotation for a specified page in the viewer.
+Update the `src/index.js` (or `src/App.js`) template to include a button that retrieves and logs the page info for a specified page. The samples below show both standalone and server-backed viewer configurations.

-By following these steps, the page info API can be integrated and used in the EJ2 PDF Viewer.
+### Conclusion
+
+By implementing these steps in the React component, you can retrieve the height, width, and rotation of any page loaded in the React PDF Viewer when a button is clicked or once the `documentLoaded` event fires. This enables inspection of page metadata for further client-side processing.
+
+### Troubleshooting
+
+- **`getPageInfo()` returns `undefined`** — Ensure the call is made after the `documentLoaded` event has fired, or invoke it from a user action that occurs after the viewer is ready.
+- **Invalid `pageIndex`** — Confirm the index is within the range `0` to `pageCount - 1`. Use the `pageCount` property to check the total number of pages.
+- **Resource loading errors (Standalone)** — Verify the `resourceUrl` matches the version of the `@syncfusion/ej2-react-pdfviewer` package installed in your project.
