Read comfortably at your own pace
Version 0.20.0. Independent text size, zoom and words-per-minute controls for document reading.
1. Publish document with layout reading. Automatic scrolling starts paused. Use the reading toolbar or kanvas_view_navigation control with navigation.action reading.
2. Commands are start, pause, resume, slower, faster and configure. The default is 220 words/minute; slower/faster use 120, 160, 190, 220, 260 and 320. Explicit wpm accepts any integer from 120 to 320. Actual scrolling uses the rendered document geometry.
3. fontSize accepts 16–40 pixels; zoom accepts 0.75–1.75. Both are independent from wpm. Pause retains your position. Touch or wheel interaction pauses automatic reading. Background tabs do not advance.
4. Use Save my defaults, or saveDefaults:true with the particular fields you intend to save. Account defaults merge text size, speed and zoom independently. New documents and sessions inherit them but never start scrolling automatically. Guest screens cannot save an owner’s personal defaults.
5. Source text, numeric strings, publication revisions and history are not rewritten by reading controls. Viewers report the observed size, speed, zoom, position and playing state.
