 | rendering               | Type of rendering: `unwrap` (default), `legacy_iframe`, or `legacy_embed`. The default value, `unwrap` shows the PDF document using pdf.js, and supports the visualisation of annotations. Other values are `legacy_iframe` and `legacy_embed` which use the legacy approach of injecting the document into an `<embed>` or `<iframe>`. They allow viewing the PDF using the viewer of the browser that contains additional features we are still working to implement in this component. **IMPORTANT**: :warning: The "legacy" methods **work only with Firefox**, and **do not support annotations**. :warning: |
