Usage

Convert a .HEIC file/Buffer to .JPG file/Buffer

Await

`
const { promisify } = require('util')
const fs = require('fs')

const Convert = require('heic')

const func = async () => {
// create a class instance
const convert = new Convert()

// path to the file to convert
const filePath = 'someFile.HEIC'

// create a buffer from buffer
const buffer = await promisify(fs.readFile)(filePath)

// .HEIC FILE -> .JPG FILE (with progress bar in terminal)
const newFile1 = await convert.cli(filePath)
console.log(${newFile1} - Done)

// .HEIC FILE -> .JPG FILE
const newFile2 = await convert.fileToFile(filePath)
console.log(${newFile2} - Done)

// .HEIC FILE -> .JPG BUFFER
const outputBuffer1 = await convert.fileToBuffer(filePath)
console.log(outputBuffer1)

// .HEIC BUFFER -> .JPG BUFFER
const outputBuffer2 = await convert.bufferToBuffer(buffer)
console.log(outputBuffer2)

// .HEIC BUFFER -> .JPG FILE
const fileName3 = await convert.bufferToFile(buffer, filePath)
console.log(${fileName3} - Done)
}
