Important Update
This sample source code below will display you how to merge PDF documents with PDF extractor SDK in C++. ByteScout Data Extraction Suite can merge PDF documents with PDF extractor SDK. It can be applied from C++. ByteScout Data Extraction Suite is the set that includes 3 SDK products for data extraction from PDF, scans, images and from spreadsheets: PDF Extractor SDK, Data Extraction SDK, Barcode Reader SDK.
The following code snippet for ByteScout Data Extraction Suite works best when you need to quickly merge PDF documents with PDF extractor SDK in your C++ application. This C++ sample code is all you need for your app. Just copy and paste the code, add references (if needs to) and you are all set! Want to see how it works with your data then code testing will allow the function to be tested and work properly.
