Getting Started with PDFix SDK

PDFix SDK is a cross-platform PDF processing tool that offers multiple integration options. The Command-Line Interface (PDFix CLI) provides a quick and easy way to add PDF processing functionality to various workflows without writing code.

Developers can leverage the SDK with different programming languages for full control over PDF documents.

Before getting started, check the system requirements to ensure compatibility with your system.

Integration Using the CLI

PDFix offers straightforward, rapid, and automated PDF processing via the command-line interface:

$ ./pdfix_app make-accessible -i test.pdf -o output.pdf

For additional CLI options, refer to the PDFix SDK Command-Line Interface documentation. The CLI application is included in the downloadable package available on the PDFix website.

Integration Using the SDK

C#

To integrate PDFix with C#, install the NuGet package PDFix.SDK:

using PDFixSDK.Pdfix;

static void Main() {
   var pdfix = new Pdfix();
   var doc = pdfix.OpenDoc("Sample.pdf", "");
   // Perform PDF operations
   doc.Close();                                       
}

C++

#include "Pdfix.h"

Pdfix_statics;

int main() {
   if (Pdfix_init(Pdfix_MODULE_NAME)) {
      auto pdfix = GetPdfix();
      auto doc = pdfix->OpenDoc(L"Sample.pdf", L"");
      // Perform PDF operations
      doc->Close();                                   
   }
}

Python

To integrate PDFix with Python, install the package pdfix-sdk:

from pdfixsdk import *

pdfix  = GetPdfix()
doc = pdfix.OpenDoc("Sample.pdf", "")
# Perform PDF operations
doc.close()

Multi-Threaded Environments

PDFix SDK is designed for single-threaded processing, meaning only one API method can be executed at a time within a single process. Any method calls from other threads will wait until the preceding one completes.

For concurrent processing, use separate processes instead of threads.
