This guide will help you run PDFTron samples and integrate a free trial of the PDFTron SDK into Python applications on Windows. Your free trial includes unlimited trial usage and support from solution engineers.
Python 3.5 - 3.8 and pip3
.
Make sure python3
and pip3
are installed in your system. You can check your python version and pip3 version by using the command in terminal:
python3 --version
python3 -m pip --version
You can install python3 and pip3 with Homebrew using the following command:
brew install python3
There are TWO steps needed before you can use PDFNetPython3
library.
Use pip3
to install PDFNetPython3
library from Python Package Index (PyPI) in terminal.
We recommend running this in a virtual environment, to guarantee the
location of where our library will be installed. Henceforth, if our library needs to be imported, be sure to activate
the same virtual environment before running a Python script that imports from PDFNetPython3
python3 -m pip install PDFNetPython3
or
pip3 install PDFNetPython3
If no errors occur, Successfully installed PDFNetPython3 ...
will display in terminal.
Download PDFNetPython3
Samples. Unzip the package and run the Samples.
Find and enter the PDFNetPython3/Samples
folder.
Run a specific sample
PYTHON
folder inside. Find RunTest.sh
and use the following commands to run it in terminal:
cd PDFNetPython3/Samples/AddImageTest/PYTHON
sh RunTest.sh
Alternatively, you can use the following commands to run AddImageTest
:
cd PDFNetPython3/Samples/AddImageTest/PYTHON
python3 -u AddImageTest.py
If no errors occur, the following lines will display in terminal:
PDFNet is running in demo mode.
Permission: write
Done. Result saved in addimage.pdf...
The output files are stored in Samples/TestFiles/output/
Run all samples
Find runall_python.sh
in the samples folder and run it.
cd PDFNetPython3/Samples
sh runall_python.sh
The output files from all tests are stored in Samples/TestFiles/output/
.
It is easy to integrate PDFNetPython3 into your application. After you have installed PDFNetPython3
via pip, all you need to do is add from PDFNetPython3 import *
to your Python script.
Below is an example called HelloWorld.py
:
# You can add the following line to integrate PDFNetPython3
# into your solution from anywhere on your system so long as
# the library was installed successfully via pip
from PDFNetPython3 import *
def main():
# You need to initialize the PDFNet library
# Before calling any PDF related methods
PDFNet.Initialize()
# This example creates a new document
# and a new page, then adds the page
# in the page sequence of the document
doc = PDFDoc()
page1 = doc.PageCreate()
doc.pagePushBack(page1)
# We save the document in a linearized
# format which is the most popular and
# effective way to speed up viewing PDFs
doc.Save(("linearized_output.pdf"), SDFDoc.e_linearized)
doc.close()
if __name__ == "__main__":
main()
To test that your code works, run the script in the folder containing HelloWorld.py
in command prompt:
python3 -u HelloWorld.py
Once you have successfully run this, you should see an output file in the working directory of this program.
Additional modules are required to run our OCRTest
or CADTest
samples, which can be downloaded here.
Be sure to merge the Samples/
directory from the module into the Samples/
directory obtained from the download in
Step 2, ensuring that the files the sample code depends on are available.
If you successfully install our PDFNetPython3
library via pip but run into errors when running a sample, it may be that your Python version is not fully compatible.
For Linux, we recommmend using Python 3.5.4, 3.6.8, 3.7.9, 3.8.5 to guarantee 100% compatibility.
You can check your python version by using the command:
python3 --version
and update your Python to the recommended versions. If errors still occur, please contact our support team.
If you cannot install PDFNetPython3
library via pip
, you need to check whether python3 and pip3 are installed in your system.
You can test it by using the following command:
python3 -m pip --version
If no errors occur and your python version is within 3.5
- 3.8
, it may be that no precompiled PDFnetPython3 library is compatible with your system. Please contact our support team. You might need to build your own PDFNetPython3 wrapper using SWIG and our PDFNetC library.
If you are running into issues with compatibility with other libraries, we recommend using our library in a
virtual environment, to guarantee the location of where our library
will be installed. Henceforth, if our library needs to be imported, be sure to activate the same virtual environment
before running a Python script that imports from PDFNetPython3
, as follows:
# Creates a venv/ folder in your current directory
python3 -m venv venv
# Activate the virtual environment in the current terminal session
source venv/bin/activate
If you want to upgrade PDFNetPython3
to the latest version, you can simply run:
python3 -m pip install PDFNetPython3
PDFNetPython3
via pip first before you could run the sample.Get the answers you need: Support
