This package is originally made by www.xpdfreader.com. This package includes xpdf tools. The tools convert pdf files to html, png, ppm, ops, text and json.

To loop extraction / conversion please see the below example:-

let xpdf = require("@aynode/xpdf");

let i = 4;
let options = [];
let loop = () => {
    options = [
        "./bin/test/test.pdf",
        "your/out/put/path" //e.g. ./hello.txt, C:/hello.ops, other.ppm, other.png, other.html, other.json (txt | ops | ppm | png | html | json)
    ];

    xpdf.convert(options, (callback)=>{
        if(callback){ console.log(callback) }

        if(i != 0){
            i--;
            loop();
        }else{
            console.log("finished!")
        }
    })
}
loop();

To extract pdf to raw text

let xpdf = require("@aynode/xpdf");

let options = [
    "./bin/test/test.pdf",
    true //true = json format, false text format
];
xpdf.extract(options, (callback)=>{
    console.log(callback)
})

To convert and save to file

let xpdf = require("@aynode/xpdf");

let options = [
    "./bin/test/test.pdf",
    "your/out/put/path" //e.g. ./hello.txt, C:/hello.ops, other.ppm, other.png, other.html, other.json (txt | ops | ppm | png | html | json)
];
xpdf.convert(options, (callback)=>{
    if(callback){
