Clear blurry background in close-focused images, by selecting click-points on the image. Works like the magic-wand tool in Photoshopp.
Installation
npm install magic-erase
Usage
var magicErase = require('magic-erase')
Configuration
// Tweak the Sensitivity for optimal result
var config = {
image: 'path-to-image', // JPG format and preferrably less than 100 kB
sensitivity: 50, // ranges from 0.1 to 100,
erasePoints: [
// a list of points on the image which will be used as the click points
// each point is <x-coordinate, y-coordinate>
// x-coordinate is from left to right
// y-coordinate is from top to bottom
// coordinates are normalized within the range 0 to 100 (i.e. percentage)
[45, 86], [87, 12], [9, 56]
]
}
API
var fs = require('fs')
var firstPass = magicErase(config).then(function (response) {
// save erased result as image file ...
var base64Img = response.base64Img
fs.writeFile('output-image.jpg', base64Img, { encoding: 'base64' }, function() {
console.log('Saved output image')
})
// use the erased result data for a second erase pass
var data = response.data
return data
})
var secondPass = firstPass.then(function(response) {
var newConfig = {
image: response,
sensitivity: 48,
erasePoints: [[8, 4], [65, 12]]
}
return magicErase(newConfig)
}).then(function(response) {
// just like in the first pass
var base64Img = response.base64Img
// use base64Img ...
return response.data
})
// .. do as many passes as you like ...
Caution
- Bigger images will take longer time
