Read, merge, split PDF in Python
GemBox.Pdf is a .NET library that enables you to process PDF files from any .NET application. But it's also a COM-accessible library that you can use in Python as well. To use GemBox.Pdf in Python, you'll need to: When working with PDF, we usually need to perform some actions, such as merging documents with familiar topics or splitting a file to extract a particular page from it. See the following example to learn how to read a PDF file, split it into multiple files, and merge PDF files using Python. Not all members of GemBox.Pdf are COM-accessible because of limitations like unsupported static and overload methods. That is why you can use the However, if you need to use many GemBox.Pdf members from Python, we recommend creating a .NET wrapper library. Your wrapper library should do all the work and expose a minimal set of classes and methods to the unmanaged code. It will enable you to take advantage of GemBox.Pdf's full capabilities, avoiding any COM limitations, and improving performnace by reducing the number of COM Callable Wrappers created at runtime.System Requirements
