## Attributes

| Name      | Type   | Default       | Description                                                                                                                 |
| --------- | ------ | ------------- | --------------------------------------------------------------------------------------------------------------------------- |
| base64    | string |               | The content of the PDF file as Base64 encoded string, without a data URL prefix. An example file is used until this is set. |
| file-name | string | 'example.pdf' | The name of the downloaded file.                                                                                            |

## Usage

```html
<c-base64-to-pdf base64={pdfContent} file-name="invoice.pdf"></c-base64-to-pdf>
```

The content is offered as a PDF download. Without the `base64` attribute, the component offers an example file (see `example.js`). If `base64` is set but empty, for example while your data is loading, it offers no download at all.

## Custom Labels

The texts users see are Custom Labels, so they can be translated in Setup with the Translation Workbench. Copy them together with the component.
