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 […]
