Server-side Meteor wrapper for PDFtk, the PDF toolkit, a tool for manipulating PDF documents.
From the pdftk man page:
If PDF is electronic paper, then pdftk is an electronic stapler-remover, hole-punch, binder, secret-decoder-ring, and X-Ray-glasses. Pdftk is a simple tool for doing everyday things with PDF documents. Keep one in the top drawer of your desktop and use it to:
- Merge PDF Documents or Collate PDF Page Scans
- Split PDF Pages into a New Document
- Rotate PDF Documents or Pages
- Decrypt Input as Necessary (Password Required)
- Encrypt Output as Desired
- Fill PDF Forms with X/FDF Data and/or Flatten Forms
- Generate FDF Data Stencils from PDF Forms
- Apply a Background Watermark or a Foreground Stamp
- Report PDF Metrics such as Metadata and Bookmarks
- Update PDF Metadata
- Attach Files to PDF Pages or the PDF Document
- Unpack PDF Attachments
- Burst a PDF Document into Single Pages
- Uncompress and Re-Compress Page Streams
- Repair Corrupted PDF (Where Possible)
You need to have PDFTK installed on the system. Downloads for all operating systems are available at https://www.pdflabs.com/tools/pdftk-server/.
For Linux, you can also run sudo apt-get install pdftk (make sure you get the latest version).
Add the package with meteor add aadams:pdftk. In your server code, you can run wrappers like this
Please Note: this method calls out synchronous, by omitting the callback
PDFTK.stamp('/path/to/in.pdf', '/path/to/stamp.pdf', '/path/to/pdfstamp/out.pdf');Note that you need to pass absolute paths to the files because the current directory when running meteor is going to be .meteor/local/build/programs/server/ when debugging, and something similar in production.
Consult the man page for command details.
The following APIs are meant to be use inside of Meteor methods.
pages(pdf, start, end)stamp(pdf, stamp, output)multistamp(pdf, stamp, output)fillform(pdf, xfdf, output)cat({first: pdf1, second: pdf2}, output)Note: the first input to the cat wrapper is an arguments object, which takes up to 8 pdfs, the first two of which are required, in the following format:
{first: pdf1, second: pdf2, third: pdf3, forth: pdf4, ...}.
Pull requests are welcome for more wrappers. If you need to execute a custom command, or one that's not wrapped, run:

Questions: It's okay to ask a question on Github Issues if you're having trouble since the volume is manageable. Just prefix your Github Issue with 'Question: ' so we can differentiate easily. Also, please make sure you've read through PDFTk documentation and tried a few things before asking. Also, please provide a cloneable Github repository if the issue is complex. For more complex questions sometimes it's hard to get all of the context required to solve a problem by just looking at text.
New Features: If you'd like to work on a feature for the PDFTk wrapper, start by creating a 'Feature Design: Title' issue. This will let people bat it around a bit before you send a full blown pull request. Also, you can create an issue to discuss a design even if you won't be working on it.
