Samples
The Samples use preset parameters and documentation to call the API of ComPDFKit PDF SDK for each function without UI interaction or parameter settings. This is achieved through modular code examples. The functions include creating, getting, and deleting various types of annotations and forms, extracting text and images, encrypting and decrypting documents, adding watermarks and bates numbers, and more.
These projects not only demonstrate the best practices for each function but also provide detailed introductions. The impact of each function on PDF documents can be observed in the output directory. With the help of the Samples, you can quickly learn how to use the functions you need and apply them to your projects.
