mindee-js

Computer vision SDK for image segmentation and document processing on top of mindee APIs

You can also check out more SDKs built on top of mindee-js

• react-mindee-js
• vue-mindee-js

Features

This SDK was made for building interfaces on top of Mindee document parsing APIs and more generally on top of any computer vision detection APIs.

• Work with images and pdfs
• Display interactive shapes on images or pdfs with custom style
• Bind custom functions to shapes mouse events
• Create multi-pages pdfs navigation sidebar
• Zoom in and out in the canvas
• Move the image with the mouse
• Create a lens to zoom around the user's pointer

This SDK was primarily made for document processing but can be used for any type of computer vision interface:

Installation

Installing with npm

npm install --save mindee-js

installing with yarn

yarn add mindee-js

Usage

Import mindee-js as a side effect in code that will be included throughout your site (e.g. your root module). This will make sure the mindee-js web components are inserted immediately upon page load.

React example

import React, { useEffect, useRef, useState } from 'react'
import 'mindee-js'

import dummyImage from 'assets/image.jpg'
const dummy_shapes = [
  {
    id: 1,
    coordinates: [
      [0.479, 0.172],
      [0.611, 0.172],
      [0.611, 0.196],
      [0.479, 0.196],
    ],
  },
  {
    id: 2,
    coordinates: [
      [0.394, 0.068],
      [0.477, 0.068],
      [0.477, 0.087],
      [0.394, 0.087],
    ],
  },
]

const Example = () => {
  const [pointerPosition, setPointerPosition] = useState(null)
  const ref = useRef(null)

  const onPointerMove = (event) => {
    setPointerPosition(event?.detail?.pointerPosition)
  }

  useEffect(() => {
    ref.current?.addEventListener('on-pointer-move', onPointerMove)
    return () => {
      ref.current?.removeEventListener('on-pointer-move', onPointerMove)
    }
  }, [])

  return (
    <div>
      <annotation-viewer
        ref={ref}
        image={dummyImage}
        shapes={JSON.stringify(dummyShapes)}
        style={{
          display: 'flex',
          width: '100%',
          height: 600,
        }}
      ></annotation-viewer>
      <annotation-lens
        image={dummyImage}
        pointerPosition={pointerPosition && JSON.stringify(pointerPosition)}
        style={{
          display: 'flex',
          width: 300,
          height: 300,
        }}
      ></annotation-lens>
    </div>
  )
}

getImagesFromPDF

This function returns a Promise that resolves with a list of images as base64 format . It takes pdf file (object URL)

import { getImagesFromPDF } from 'mindee-js'

getImagesFromPDF(file).then((images) => {
  // Do something with images pdf pages
})
