pdftk | Mirror of pdftk - | Document Editor library

I'm using nodejs and I'm processing PDFs. One thing I'd like to do is to outline all the fonts of the PDF (so that they are not selectable with the mouse cursor afterwards).

I tried the pdftk's flatten command (using a node wrapper), but I did not get what I wanted.

I may have a track in using inkscape (command line), but I'm not even sure about how to do it. I really am looking for the easiest way to do that using nodejs.

There might also be a track using ghostscript: https://stackoverflow.com/a/28798374/11348232. One notable thing to notice is that I don't use files on disk, but Buffer objects, so it'd be painful to save the PDF locally then use the gs command.

Thanks a lot.

I have tried to use pdftk to fill a PDF form with text and images. Filling out text fields works fine, but it cant seem to add an image to an PDF form image field.

Is there any way to add an image to a form field with pdftk ? Or any other way to do this?

Heres my pdf: https://easyupload.io/b1emej

Heres my code

I am working on editing a PDF form/template in Ruby On Rails application. I want to populate some of form fields with data from database and make few fields editable to take the input from user. I found PDFtf but I read that this is very old library and hardly works with the new Linux/Mac versions. I checked https://www.adamalbrecht.com/blog/2014/01/31/pre-filling-pdf-form-templates-in-ruby-on-rails-with-pdftk/

I'm trying to use the update_info command in order to add some bookmarks to an existing pdf's metadata using pdftk and powershell.

I first dump the metadata into a file as follows:

pdftk .\test.pdf dump_data > test.info

Then, I edit the test.info file by adding the bookmarks, I believe I am using the right syntax. I save the test.info file and attempt to write the metadata to a new pdf file using update_info:

pdftk test.pdf update_info test.info output out.pdf

Unfortunately, I get a warning as follows:

pdftk Warning: unexpected case 1 in LoadDataFile(); continuing

out.pdf is generated, but contains no bookmarks. Just to be sure it is not a syntax problem, I also ran it without editing the metadata file, by simply overwriting the same metadata. I still got the same warning.

Why is this warning occurring? Why are no bookmarks getting written to my resulting pdf?

After some initial problems I was finally able to set up a self-hosted GitLab Runner on my personal laptop.

I'm now looking into how this runner works and how I can tweak it's environment to my needs. I modified the YML file to run a simple command echoing the PATH environment variable:

I was given a .zip file that had an external library called Python PDF Toolkit, often abbreviated as pdftk or pypdftk.

To my current knowledge, this external dependency was built on a EC2 instance of CentOS6, because the pdftk has its own dependency called libgcj.

As you can see from the image, most of the files are Unix Executable Files, and are missing their file extensions.

1. Will this create problems in Lambda? I believe the pdftk needs to be uploaded as a Lambda Layer to help extend the standard core Python Library.

2. If this will create problems executing Lambda, are there any steps I can take to find the file extensions?

Lastly, I can edit this question and add the code within these files if you believe that will help.

EDIT 3:
So the problem may likely be in the set-up and configuration of my Lambda Layer Dependencies. I have a /bin directory containing 3 files:

• lambdazip.sh
• pdftk
• libgcj.so.10
  

pdftk is a pdf library, and libgcj is a dependency for PDFtk.
lambdazip.sh seems to set & modify PATH Variables.

I have tried uploading all 3 as 1 lambda layer.
I have tried uploading all 3 as 3 separate lambda layers.
I have not tried customizing the .zip file names, I know sometimes the Lambda Layer wants you to name the .zip file a specific name dependent on the language.
I have not tried customizing the "compatible architectures" & "compatible runtime" lambda layer settings.

EDIT 2:
I tried renaming the Lambda Layer as Python.zip because I heard that sometimes you need a specific naming convention for the Lambda Layer to work correctly. This also failed & produced the same error.

EDIT:
I have tried pulling the .py files out of the /surveys directory, so when they are zipped, they are in the root folder, but I still receive the same error: Runtime.ImportModuleError: Unable to import module 'lambda_function': No module named 'surveys

Which files do I need to zip? Do I need to move certain files to the root?
I learned that I had accidentally zipped the directory which commonly caused this error.
I needed to zip the contents of the directory, which is a common solution.
Unfortunately this did not work for me.

I have a Lambda Function, and the code I have uploaded is a zipped folder of my /Archive directory.
From what I understand, many of the people who run into this "[ERROR] Runtime.ImportModuleError: Unable to import module 'lambda_function':" have issues because of their Lambda Handler.

My Lambda handler is: lambda_function.lambda_handler so this doesn't appear to be my issue.

Another common problem I've noticed on Stackoverflow, appears to be with how people are compressing & zipping the files they upload to the Lambda Function.

Do I need to move my lambda_function.py? Sometimes this CloudWatch error occurs because the lambda_function.py is not in the ROOT directory.

Does my survey directory need to move?

I think the folders & directories I have here may be causing my issue.

Do I need to zip the directories individually?

Can I resolve this error by Zipping the entire project?

For more information, I also have a Lambda Layer for PDF Toolkit, called pyPDFtk in the codebase. In that Lambda layer is a zipped /bin with binaries inside.

If there is anything I can alter/change within my code or AWS configuration, please let me know, and I can return new CloudWatch error logs for you.

lambda_function.py

I would like to include the result of a string concatenation command as part of a call using the pdftk command line tool. Here's what I tried:

I have several python executables available from within a default powershell prompt as shown by where.exe python:
