C++ PDF library integration

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

• Visual Studio Make sure that the Desktop development with C++ workload and Windows 8.1 SDK are part of your installation. This guide will use Visual Studio 2017. The Troubleshooting section has information about other versions.
• Apryse's C++ PDF library for Windows:

Download the SDK

download Windows 64-bit Apryse SDK

1. Extract the folder from the .zip file.

This article uses PDFNET_BASE as the path into the folder that you extracted.

1PDFNET_BASE = path/to/extraction/folder/PDFNetC(64)/

1. Get your Apryse trial key.

Navigate to the location of extracted contents. Find and enter the Samples folder (PDFNET_BASE/Samples). Here you can find sample code for a large number of features supported by the Apryse SDK.

Find Samples_VC20XX.sln inside the Samples folder and open it with Visual Studio. Choose the appropriate solution based on your Visual Studio installation.

Run a specific sample

1. Find the sample you want to run and set it as the Startup project.If you're running into issues, see the Troubleshooting section.
2. Run the project.

Run all samples

1. Make sure that the target type for the debugger is set to the right type for your machine and your Apryse SDK Download. Click on Local Windows Debugger to run all the samples.

If you prefer using command line to compile and run code, have a look at the Advanced section.

This section will help you build the "Apryse Hello World" application. It is easy to integrate the rest of Apryse SDK if you are able to open, save and close a PDFDoc.

Before writing the application, some dependencies needed to be with Visual Studio.

1. Create a new C++ Console Project for Windows called myapp.
2. Add PDFNET_BASE\Lib\PDFNetC.lib to the project's Additional Dependencies in the Linker Input settings.
3. Add PDFNET_BASE\Headers to the project's Additional Include Directories in the C/C++ General Settings.
4. Copy the PDFNET_BASE\Lib\PDFNetC.dll file to the project's output directory. Verify that the right version of PDFNetC.dll was added from the path used to add the reference.

The Troubleshooting section below has more detailed instructions for newcomers to Visual Studio.

Replace the contents of myapp.cpp with:

1``` cpp
2
3#include <iostream>
4
5// Important for PDF related manipulations
6#include <PDF/PDFNet.h>
7#include <PDF/PDFDoc.h>
8
9// Important for document filesystem interaction and more
10#include <SDF/ObjSet.h>
11
12using namespace pdftron;
13using namespace PDF;
14using namespace SDF;
15
16
17int main()
18{
19    try
20    {
21        // This is required before any Apryse related
22        // classes and methods can be properly used
23        PDFNet::Initialize("YOUR_APRYSE_LICENSE_KEY");
24
25        PDFDoc doc;
26
27        // Create a new page and push it into
28        // the page sequence of the document.
29        Page page = doc.PageCreate();
30        doc.PagePushBack(page);
31
32        // Save the document as a linearized PDF which is the most
33        // popular and effective fast viewing format
34        doc.Save("linearized_output.pdf", SDFDoc::e_linearized);
35    }
36    catch (pdftron::Common::Exception& ex)
37    {
38        std::cout << ex.GetMessage() << std::endl;
39    }
40    return 0;
41}
42```

You can use the Local Windows Debugger button to build the solution and run the main function.

Once the code has been run, you can find a new document called linearized_output.pdf in the output directory of your project.

You can learn about and add more features by reading our guides, samples and API.

Run samples using batch files and command prompt

1. Navigate into the folder for any sample that you like (PDFNET_BASE/Samples/X).

2. Create a new file inside the CPP folder called RunTest.bat. Paste the following code in it (replace X with the name of the Test folder):Save the file.

1@echo off
2setlocal
3REM Replace X with the name of the Test folder, Ex. FDFTest
4set TEST_NAME=X
5if not exist PDFNetC.dll copy "%cd%\..\..\..\Lib\PDFNetC.dll" PDFNetC.dll
6cl /EHsc /I"../../../Headers" ../../../Lib/PDFNetC.lib %TEST_NAME%.cpp
7%TEST_NAME%.exe
8endlocal
9PAUSE

3. Open the Windows Start Menu and in Apps, scroll down and find the Visual Studio 2019 folder (not application). Expand it and click on Developer Command Prompt for Visual Studio 2017. Navigate to the test folder on your system.

4. Use the following to compile, build and run the test:RunTest.bat
