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
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
