TesseraxLive

This package provides a LiveComponent to be used with LiveView that creates a canvas HTML component. Furthermore, this package utilizes Tesserax, which uses Tesseract OCR, to recognize the drawn text inside the canvas HTML component.

Usage

In ./assets/js/app.js add

...
import { TesseraxCanvas } from "tesserax_live"

let Hooks = {};

Hooks.TesseraxCanvas = TesseraxCanvas;

...
let liveSocket = new LiveSocket("/live", Socket, {
    ...
    hooks: Hooks
})
...

In your LiveView HEEx, add the following

~H"""
...
<.live_component module={TesseraxLive} id="canvas-ID" />
...
"""

Use the interface functions to interact with the canvas component:

• read/1: reads the image in the canvas and sends it for recognition with Tesserax.
• read/2: takes a path to an image (e.g. file upload) and uses Tesserax to read the image.
• set_opts/2: sets opts in the %Tesserax.Command{} struct.
• reset/1: resets the canvas component.
