Merge PDF Files
It is a Windows library that merges standard PDFs into a final PDF
... or asynchronous.
We want to give you a benchmark, the library was used to create a PDF from single page(scanned) image by an OCR SDK (it is not included in our library, you can use any on the market):
20,000 Images (the OCR SDK creates single page PDF text searchable, running 50 threads) in 80 minutes. The size of the final PDF searchable was 800Mb.
If you download the library, we provide a sample which cover all the scenarios possible (synchronous and asynchronous).
