**Beware this is a WIP in its early stages!**

The goal of this project is to have a lib that allows you to programmatically read from (and possibly write to) PDF files. It is meant as a low-level PDF file editor API.

## Features

Basic PDF info:

    const pdf = pdfhacker('test.pdf');

       

    > console.dir(pdf.version);

    {

      major: 1,

      minor: 5

    }

Simple text replacement:

    pdf.replace('foo', 'bar').saveTo('out.pdf');

Will replace all occurrences of ``foo`` with ``bar``, finally saving to file ``out.pdf``.

Chaining:

    pdf

      .replace('foo', 'bar')

      .replace(/\d{3}/, '456')

      .saveTo('out.pdf');

Will replace all occurrences of ``foo`` with ``bar`` and will also replace all ``123`` with ``456``, finally saving to file ``out.pdf``.

Display object tree:

    > pdf.dumpTree();

    Root

    |- Catalog

       |- Page 1

       |- Page 2

       ...

Change specific objects:

    pdf('/Root/Catalog/Page 1/Text')[0].val('first text object will be affected');

    pdf('/Root/Catalog/Page 1/Text').val('all page 1 text objects will be affected');
