title: "Whiteboard Ink"
description: "A whiteboard sketch draws one measured stroke at a time while a pen nib follows the active tip. Preset sketches (bulb, flow, rocket) or your own multi-stroke SVG paths via the strokes slot; a path marked data-ink=accent rides the accent token."

```html whiteboard-ink.html
Whiteboard Ink
```
## Install
That writes one file: `compositions/components/whiteboard-ink.html`.
## Paste it into your composition
Open `compositions/components/whiteboard-ink.html` and copy what is inside into your own composition.
A component has no size or duration of its own. It takes both from the composition
you paste it into.
## Variables
Every one of these has a default, so the piece works untouched. Set the ones you
want to change on the element:
| Variable | Default | Accepts | What it does |
| --- | --- | --- | --- |
| `sketch` | `bulb` | `bulb`, `flow`, `rocket` | Authored preset sketch to draw. Ignored when the strokes slot holds custom paths. |
| `caption` | `Draw the idea` | string | Short line shown after the sketch completes. |
| `pen` | `show` | `show`, `hide` | Show or hide the pen nib actor. |
| `accent` | `green` | `green`, `blue`, `violet` | Color used by strokes marked data-ink=accent (one highlight stroke in each preset). |
| `exit` | `none` | `none`, `fade`, `up` | How the completed lockup leaves. none holds the final frame. |
Set them with `data-variable-values` on the element that mounts it. These are the
defaults, so this behaves exactly like the preview above until you change one:
