I am able to use many pdfs, but I have one that is giving me the error:

Invalid xref stream index: index says 1 objects, but space for 42

As the error suggests, there are 42 fields on the pdf form that should be fillable, but only the first one appears. That first field is a "Clear All" action that appears as a checkbox in the demo fields area. I can attach a link to the pdf in question if that helps. Thanks!

Hello,
I'm encountering a problem with the filled pdf file. it can't be opened with Adobe acrobat reader, and it shows me this error : There was an error opening this document. This file is damaged and could not be repaired.
Can you help me with that ?
Many thanks.

I'm still new to javascript to bear with me, but when I use the npm package, imported like this
import * as pdfform from 'pdfform.js';
it get this error:

ERROR in ./node_modules/pdfform.js/dist/pdfform.minipdf.dist.js
Module not found: Error: Can't resolve './minipdf.js' in 'C:\Users\Jason\git\dev\globalflyte-webapp\node_modules\pdfform.js\dist'
ERROR in ./node_modules/pdfform.js/dist/pdfform.minipdf.dist.js
Module not found: Error: Can't resolve './minipdf_js.js' in 'C:\Users\Jason\git\dev\globalflyte-webapp\node_modules\pdfform.js\dist'

but everything is fixed when i just copy everything into /dist/ like this:

I think this is either an error with the npm package or I'm doing something wrong.

First of all, I love the demo. Thanks for that.

My goal: We have many fillable forms that we will be printing in our web app. One of them is the Buyer's Guide: https://www.ftc.gov/system/files/documents/plain-language/cfr_buyers_guides_english.pdf.

The user will not be uploading the document each time they want to print it. We want to save the PDF in our files and have the code find the PDF, fill it out, and then print it.
I ran into an error that I'd appreciate your help on a lot.

What I've done so far...

1. run NPM
   
2. imported pdfform into the component.
   
3. I did not import the <script> into the index.html.
4. created a function in the component mentioned in #2 above
   
   This is the error I am receiving.
   

doing the following

1. npm i --save pdfform.js
2. node
3. require('pdfform.js')
   gets the following results:

> require('pdfform.js')
Error: Cannot find module './libs/pako.min.js'

why not just npm install --save pako and require it directly, instead of requiring this custom step?

When you give a checkbox value of true, it doesn't get properly transformed by the library and just stays false. Does anyone know why that's happening?

while upleading a pdf I am getting incorrect header check
Fill the details and download the pdf --> all fields are empty

It cannot fill fields with non-english text eg. કંઈક

Hi, I got an error when implement in my local laptop, anyone could help me?

pdfform.pdf_js.js:formatted:2911 Uncaught Error: stream must have data

source code:

<?php ?>

<script src="js/pdfform.pdf_js.js"></script>
<script>
    var pdf_buf = "template2.pdf" // load PDF into an ArrayBuffer, for example via XHR (see demo)
    var fields = {
        'name': 'test',
        'checkbox': "True"
    };
    var out_buf = pdfform().transform(pdf_buf, fields);
    // Do something with the resulting PDF file in out_buf
</script>

Some bug causes the size of the Pdf used ( if repeatedly used to fill out) to grow exponentially large.
Any idea what is causing this?

Hi,

Do you have any support for checkboxes? When I click "Fill and Download" on the demo, all of the fields are numbered in order but it skips the checkboxes.

For an example you can see the pdf I emailed you yesterday.

Thank you!

pdf-test.pdf

I tried the PDF above, and the radio buttons are not recognized. When debugging into pdfform.js, I noticed that n.map.Opt doesn't exist, thus radio button logic was not executed.

Hi, thanks for your great work with this library.

I have a pdf with can be filled without problems on the official demo page.
If I load it via fetch, and convert it to an Array Buffer via resonse.arrayBuffer() I get the following exception:

Uncaught (in promise) Error: Invalid xref stream index: index says 1 objects, but space for 12

I created a csb to demonstrate my Problem:
https://codesandbox.io/s/youthful-swanson-jm9pm

import React, { useEffect } from "react";
import ReactDOM from "react-dom";

const pdf = require("./pdfform.minipdf.dist");

function App() {
  useEffect(() => {
    // both form.pdf and beratungsprotokoll.pdf are working
    // with the official demo at:
    // https://phihag.github.io/pdfform.js/docs/demo.html
    // loaded via fetch() however both produce
    // an xref error:
    // Invalid xref stream index: index says 1 objects, but space for 12
    fetch("https://jm9pm.csb.app/beratungsprotokoll.pdf")
      .then(res => res.arrayBuffer())
      .then(pdfArrayBuffer => {
        console.log(pdfArrayBuffer);
        console.log(pdf());
        console.log(pdf().list_fields(pdfArrayBuffer));
      });
  }, []);
  return <div>see console for status</div>;
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);

Would you be able to put together an example usage for this?

Is it possible to set the font size and type using this library?. if possible can you provide how to set font size?.

Uglify does not remove require() statements, which makes the pdfform.minipdf.dist.js not usable. One should use Rollup, Webpack or Browserify.

Hi there,
Great work. I tested on a governmental form https://www.dol.gov/whd/forms/WH75EN.pdf and see that fields are not uniquely recognized so one single data point is repeated filled into form.

Thank you for the attention.

I want to use this package server side. Is it possible?

I just make a typescript version for this repo repo,
done some fix on checkbox and muilt showed text;

It would be awesome if you could add support for inserting images, it would be useful for adding photos and signatures

When I load the PDF there are some fields are missing and says it is corrupted on my laptop
pdfform.js_generated (1).pdf
"There was an error opening this document. The root object is missing or invalid." ON adobe after downloading. It seems to work on chrome in the url

Hi,

pdfform.js is a fantastic utility! I got it to work satisfactorily on my project to generate a filled-out character sheet for Dungeons & Dragons fifth edition: https://github.com/drogoganor/dndcharactermaker

However, I did get an error with the fillable form which I had to work around. Here's the PDF: https://media.wizards.com/2016/dnd/downloads/5E_CharacterSheet_Fillable.pdf

The error was 'doc.acroForm.map.Fields.slice is not a function' on line 291 of pdfform.js, in the function 'function visit_acroform_fields(doc, callback)'. My solution was to make this check always false, which makes the function use the fallback logic which worked. I just thought you might want to know.

Thanks again!

Hi there,
Great work. I tested on a governmental form https://www.dol.gov/whd/forms/WH75EN.pdf and see that on the 3rd page, at the beginning, we see 'Workweek Ending Date' and the person who created to form forgot to add an input field. Therefore, if we use pdfform.js at its current stage, it will not allow user to specified co-ordinates to fill text on top of the PDF file.

Thank you for the attention.

Hello, I have a problem with the letters

1. Ə

Hello,

I tried to use use your online demo with this pdf : https://formulare.bmf.gv.at/service/formulare/inter-Steuern/pdfs/2019/L16.pdf?open=download

and I couldnt fill the Checkboxes. Is it because of the demo or is it also in the original version?

I'm using pypdftk in an app but researching if it's possible to move everything into client side. One option i'm using is to flatten the file, turning the form into a regular non editable pdf. Does this project offer such an option?

Hi, when I load my pdf into the online demo, I get any error saying I have a missing trailer. I've found a trailer in my pdf. Any ideas?

Does anyone try it? I'm having a problem with the minipdf.js file

For example; character ≤ is replaced with "d

Can't anyone make it just work? I'm trying various ways to implement it - npm, via script tag, programatically...Come on, it should be plug'n'play

I was hoping you could point me in the right direction for a trick I'm trying to pull off.

I'm trying to duplicate and add an acroform field directly into the saving PDF. I assume it can be pulled off by parsing the PDF object array and duplicating an already created field into the stream. If you have any insight into how this could be accomplished, I would appreciate the advice.

I've successfully been able to modify the PDF acroform fields locations and names using your code but haven't been able to generate new field inputs.

Thanks again, and awesome project.

Hi Phillip,

I noticed an issue when reading fields from PDF where the Field Dictionary (which contains the fields name and value) is the parent of the Annotation Dictionary. The current code only works when the two Dictionaries are merged together. I'm not sure how this affects the actual form filling logic though.

I have been unable to use any of my own PDFs - built from scratch or already available. Are there parameters or pdf version requirements?
