We are using the custom shared components called PDF Tools custom nodes. One of

Assuming you want to use the rotation offered by the browser plug-in then they will have to rotate and save to their local computer and you will have to offer the possibility of uploading a new version of the document either in the same form or in the next form via File Upload Component; the node will bot pull it from her computer, the user will need to select Upload and provide the rotated file.

In the approach of building your own plug-in I was thinking more about:

1. Show the original PDF
2. Show a dropdown with standard rotation options (e.g. 90`, 180`, etc)
3. The user selects one option from the dropdown and submits the form
4. Between the form 1 and the form 2 (which will display the final result) you place your custom plug-in which does the rotation

For images there's already a plug-in that does image manipulation such as crop, trim, square and resize meaning you could use the approach #2 I describe in 4 steps above to test this and then enahnce the plug-in to do rotation.

The plug-in is called Image Utilities (doesn't offer rotation but is a good example) forum.appian.com/.../summary
