# clearMarkElements

> Clear handwriting elements in a DOC file.

Handwriting elements in DOC are not written directly into the DOC file, but into its corresponding mark file.

```ts wrap theme={null}
static clearMarkElements(filePath: string, page: number): Promise<APIResponse<boolean>>;
```

**Parameters**

| Parameter  | Type     | Description                  |
| ---------- | -------- | ---------------------------- |
| `filePath` | `string` | DOC file path                |
| `page`     | `number` | Page index (starts from `0`) |

**Returns**

* [`APIResponse<boolean>`](/en/api-reference/supernote-plugin/types/api-response): `result === true` indicates clearing succeeded

## Example

```ts wrap theme={null}
import { PluginFileAPI } from 'sn-plugin-lib';

/**
 * Clear a page mark element example.
 */
export async function exampleClearMarkElements() {
 const filePath = '/storage/emulated/0/Note/demo.pdf';
 const page = 1;

 const res = await PluginFileAPI.clearMarkElements(filePath, page);
 if (!res.success) {
 throw new Error(res.error?.message ?? 'clearMarkElements call failed');
 }
 return res.result;
}
```
