Custom Python wrapper for PDF library integration

There are three ways to use Apryse with Python:

  • Use pip - the precompiled library for Python 2.7.x .
  • Use pip - the precompiled library for Python 3.x .
  • (less common) Use PDFNet bindings to build your own wrappers.

This guide will help you get started by building your own wrapper. You can find more information about using the precompiled library

Custom Python wrapper & macOS PDF library integration

This guide will help you run Apryse samples and integrate a free trial of the Apryse SDK into Python applications on macOS. Your free trial includes unlimited trial usage and support from solution engineers.

Prerequisites

  • Python3 or Python2 with developer extensions
  • CMake version ≥ 2.8
  • SWIG 2.0.4 - 2.0.12 or SWIG 3.0.12 or SWIG 4.0.2 and above
  • Apryse's Python3 PDF library for macOS:

Download the SDK

Run Apryse SDK in production
A commercial license key is required for use in a production environment. Please fill out our licensing form if you do not have a valid license key.
Keep your commercial license key confidential.
License keys are uniquely generated. Please make sure that it is not publicly available (e.g. in your public GitHub).

Initial setup

  1. Make a directory to store the wrappers and navigate into that directory.

  2. Clone the uncompiled PDFNet wrappers project by executing

    git clone https://github.com/PDFTron/PDFNetWrappers
  3. Navigate to PDFNetWrappers/PDFNetC and move the downloaded [PDFNet C/C++ SDK] for macOS(#prerequisites) into that directory and unzip it. Ensure you obtain the right architecture for your Python interpreter. This can be done with these two commands:

curl -L -O http://www.pdftron.com/downloads/PDFNetCMac.zip
unzip PDFNetCMac.zip
  1. Now to move the headers in place, make sure you are in the PDFNetWrappers/PDFNetC directory and execute

    mv PDFNetCMac/Headers/ .

    and

    mv PDFNetCMac/Lib/ .

    to move the PDFNet libraries in place.

    You can delete PDFNetCMac.zip to free up space.

    Your /PDFNetC folder should be laid out like this like this:

    PDFNetC
    ├── Headers
    ├── Lib
    ├── PDFNetCMac
    └── README.txt
  2. Make a build directory inside /PDFNetWrappers and navigate to it. This guide will assume the build directory is called Build.

  3. Execute

    cmake -D BUILD_PDFNetPython=ON ..

    If all goes well, you should get a message which reads:

    Build files have been written to ~/PDFNetWrappers/Build
  4. Execute make followed by sudo make install.

  5. Next we need to fix the rpaths issue on Mac. While still in the same Build directory, execute these lines:

cp ../fix_rpaths.sh ../PDFNetC/Lib/
cd ../PDFNetC/Lib/
sudo sh ./fix_rpaths.sh
  1. Get your Apryse trial key.

Apryse collects some data regarding your usage of the SDK for product improvement.

If you wish to continue without data collection, contact us and we will email you a no-tracking trial key for you to get started.

You are now ready to run the samples or integrate Apryse SDK into your own application.

Also check out the source for the PDFNetC wrappers here.

Run the samples

Running a specific sample

  1. Navigate to the PYTHON folder in the sample, for example /Samples/AddImageTest/PYTHON and execute ./RunTest.sh.

Run all samples

  1. To run all tests, navigate to /Samples and execute

    ./runall_python.sh

    The tests will run one by one.

Output files will be in /Samples/TestFiles/Output

Integrate into your application

This section will show you how to use our SDK to create a simple Apryse "Hello World!" application. It will create a document with one blank page and save it as a linearized PDF in its running directory.

  1. Navigate to the /Samples directory and create a new directory called myApp (if it does not exist already). This guide will assume your application is named myApp. For organization, create a new directory inside myApp called PYTHON.

  2. Navigate inside that PYTHON directory and create a new Python file called myApp.py. Open it with your favorite text editor and paste this into it:

    import site
    # below is the relative path to Apryse PDFNetC libraries
    site.addsitedir("../../../PDFNetC/Lib")
    import sys
    from PDFNetPython import *
    
    def main():
        PDFNet.Initialize("YOUR_APRYSE_LICENSE_KEY")
        doc = PDFDoc()
        page = doc.PageCreate()         # Start a new page
        doc.PagePushBack(page)          # Add the page to the document
        doc.Save("output.pdf", SDFDoc.e_linearized);  # Save the document as a linearized PDF
        print("Hello World!")
    
    if __name__ == '__main__':
        main()
  3. Run your application via python myApp.py. If all goes well your output should read:

    PDFNet is running in demo mode.
    Permission: write
    Hello World!

Check the output.pdf that the program output in the same directory. It should be a PDF with one blank page.
