The PDF Pointer Control app (app/pdf-pointer-c) is the phone and tablet controller for the PDF Pointer Display app (app/pdf-pointer). Together they show a local PDF on a shared screen with a remote controlled pointer.

This app lets a phone, tablet, or desktop browser choose a local PDF file and send it to a pdf-pointer display in the same RCWeb room. After the display loads the document, the controller provides simple vertical scrolling and a touch pad for moving the pointer over the PDF.
The control app is designed for touch use. The main actions are large: Select PDF, Scroll Up, Scroll Down, and the pointer touch area.
/pdf-pointer/ on the main display..pdf file and shares it with the display.Several controllers can be open in the same room, but the PDF file is hosted by the controller that selected it. If that controller is closed, other controllers can still send pointer and scroll commands, but the display may not be able to reload missing PDF data.
Use this app with PDF Pointer Display (app/pdf-pointer).

Keep this tab open while presenting. Closing or refreshing it can stop the display from loading the PDF.
