A PDF Signature can be used to create and sign digital signatures on PDF documents, which protects the security of documents’ contents and avoids it from being tampered with maliciously. It can let the receiver ensure that the document is released by the signer and the contents of the document are complete and unchanged. Foxit […]

Foxit PDF SDK provides a range of encryption and decryption functions to meet different levels of document security protection. Users can use regular password encryption and certificate-driven encryption, or use their own security handler for custom security implementation. Example: How to encrypt a PDF file with password #import "ViewController.h" #import ... // Encrypt the source […]

PDF rendering is done with the Foxit renderer, a graphic engine that is used to render pages to a bitmap or a platform device. Foxit PDF SDK provides APIs to set rendering options/flags. For example, to set a flag to decide whether to render form fields and a signature, whether to draw anti-aliasing images and […]
