・Added two-up mode (displaying two pages side-by-side) and it can be displayed in PDFView.
・Added cover mode (only available in two-up mode) and it can be displayed in PDFView.
・Added API for annotation permissions (accessing and setting all annotation permissions such as Hidden, ReadOnly, Locked, etc).
・Added API for editing document permissions (setting related operations shall be permitted when the document is opened with user access, used with encryption).
This is the first release of ComPDFKit PDF SDK, it is a new Rapid Development Kit for iOS/Android/Windows platforms which focuses on helping developers rapidly integrate powerful ComPDFKit PDF technology into their own apps. With ComPDFKit, even developers with limited knowledge of PDF can quickly realize a PDF Viewer with just a few lines of code. Now, it is available on iOS, Android, and Windows platforms.
ComPDFKit provides an Objective-C API for iOS and consists of two feature elements:
PDF Core API
The Core API can be used independently for document rendering, analysis, text extraction, text search, form filling, password security, annotation creation and manipulation and much more.
The PDF View is a utility class that provides the functionality for developers to interact with rendering PDF documents per their requirements. The View Control provides fast and high quality rendering, zooming, scrolling, and page navigation features.
This version release highlights include:
・High performance PDF libraries to render PDF pages, page objects, annotations, and forms the way they were intended to be viewed: sharp, clear, accurate, and easy to read.
・APIs for annotation creation, properties access, and modification (appearance setting and drawing). It also provides APIs to export and import all annotations from and to XFDF documents. The APIs support the following annotation types: note (text), free text (text box), line, square, circle, highlight, underline, squiggly, strikeout, stamp, ink (freehand), popup, and sound.
・A powerful method to view existing forms, modify form fields, add and remove form fields, create new forms, allow users to fill in forms, export and import form data by XFDF file, access form data, and set or read form field values and properties.
・Merge and combine specified page ranges from different PDF files into a single PDF. Split one PDF into separate PDFs based on page ranges. Developers can merge PDF files (partial or whole), extract any pages from a PDF to save as a new PDF, and delete specific pages from a PDF file.
・A range of encryption and decryption functions to meet different levels of document security protection. It allows users to implement password encryption, set or modify security permissions associated with a document, and allows developers to remove encryption from existing PDF documents.
