Installation

Install via NPM:

const filepix = require("filepix");

import * as filepix from "filepix";

Convert images to PDF

this feature let you convert your images into a single pdf file

filepix.img2PDF(pages = './inputImagesDir', output = "./outputImageDir/output.pdf");

or maybe your images file in different path for this case you can use below code:

filepix.img2PDF(
  pages = [
        './1.jpg',
        './public/upload/2.jpg',
        './public/upload/example/3.jpg'
  ],
  output = "./outputImageDir/output.pdf");

Add effects

Color

Apply multiple color modification rules

let options = {
   effects: [
              {
                  name: 'color',
                  config: [{ apply: 'green', params: [100] }]
              }
            ]
  };
filepix.img2PDF(pages = './inputImagesDir', output = "./outputImageDir/output.pdf", options);

Flip

Flip the image horizontally or vertically. Defaults to horizontal.

let options = {
   effects: [
              {
                  name: 'mirror'
              }
            ]
  };

let options = {
   effects: [
              {
                name: 'flip',
                config: {
                    vertical: true
                }
              }
            ]
  };
filepix.img2PDF(pages = './inputImagesDir', output = "./outputImageDir/output.pdf", options);

Blur

A fast blur algorithm that produces similar effect to a Gaussian blur

let options = {
   effects: [
              {
                name: 'blur',
                config: {
                    pixels: 50
                }
              }
            ]
  };

Rotate

Rotates the image clockwise by a number of degrees. By default the width and height of the image will be resized appropriately.

let options = {
   effects: [
              {
                name: 'rotate',
                config: {
                    ratio: 45

Add watermarks

you can add watermark to all images and merge them as single pdf by set below option path: watermark image path position: watermark position (center,right,right-bottom,center-bottom,left-top,left-bottom)

options = {
  watermark: {
            type: 'image',
            path: '../logo1.jpg',
            ratio: 0.2,
            opacity: 0.2,
            position: 'left-bottom'
  }
}

Convert pdf to images

this feature let you convert your pdf into multiple images.

filepix.PDF2img('./inputImagesDir/input.pdf', "./outputImageDir");

Convert pdf to word document

NOTE: this method using OCR so first, you need to install the Tesseract project. Instructions for installing Tesseract for all platforms can be found on the project site.

after installing Tesseract you can easily convert your pdf into file as docx format by calling below code:

await filepix.pdf2docx('./inputImageDir/input.pdf', './outputImageDir/output.docx');

Custom Language

1- find your LangCode from here 2- download proper .traineddata file from here and copy it on your local machine in Tesseract-OCR/tessdata directory 3- finally use below code:

await filepix.pdf2docx('./inputImageDir/input.pdf', './outputImageDir/output.docx',  options = { lang: "deu" });

Convert png to jpg

convert png format into jpg even you can compress your image.

await filepix.png2jpeg('./input.png', './output.jpg'
, options = {
  quality: 50
});

base64 to jpg or png

convert base64 to png or jpg by calling below method.

await filepix.base64ToImg('base64Str', './outputImageDir/output.png', { extension: 'png' });
