To draw something into a PDF document, you use the standard Android Canvas drawing calls (including drawing, transformations, clips, etc.) on an instance of PDFCanvas. The class PDFCanvas implements the graphics operations defined by the standard Android Canvas class. This library is derived from the GnuJPDF library, which provides similar functionality for the Java AWT graphics system, and as such is similarly released under the LGPL License. Note that Android version 5.0 has this functionality as part of the standard API however, earlier versions did not provide PDF generation, and the Android support library didn’t include this as of the time of this writing. A sequence of Android Canvas drawing method calls will thus create a structured PDF document that, when viewed with a standard PDF reader, will display the corresponding image. The library provides a special Canvas subclass, PDFCanvas, that is associated with a PDF document and that renders draw commands into PDF syntax. It also has a liberal open source license with no royalties.The GnuAPDF library provides support for generation of PDF files using standard Android “draw” commands. It has a very, simple, logical, clean and easy PDFjet source Code. The other advantage of PDF Jet is that it allows for writing PDF to a stream. It is much more intuitive than other products, and is dynamic and very flexible in handling everything from very simple reports to highly complex work like dynamic brochures containing many graphics. PDF JET is an extremely powerful tool that provides a complete PDF generation library and allows for the creation of very complex PDF documents using advanced features for drawing and text. The JPEG 2000 image decoder is not yet implemented.With the exception of Grayscale, RGB, CMYK, ICC color spaces are not yet implemented.Android PDF SDK does not render filing and gradient painting.Files with a password cannot be used on the Android PDF SDK.Not all shader types can be used at the moment.Highly optimized rendering and parsing performance.It supports all versions of Andorid 2.2 as well as higher versions like ginger bread and honeycomb.Īndroid PDF SDK has managed to implement the following features:.It complies fully to quality standards: It supports all versions of PDF formatting including ISO32000.The ability to highly customize Android widgets every user has a fine-grained control to each of their experiences as the Android PDF library includes widgets which have full-source codes for access.Easy-to-use tools for innovation and development: Android PDF library offers the support needed for advanced features like full text search, links, text selection, manipulation, bookmark navigation, interactive forms, annotations, and PDF markups like underline, strikethrough, rectangle, line, arrow, free-hand-tool, and sticky notes.Robust graphic support that is rich: It supports all forms of PDF files.Standout performance: The Android PDF library offers great zoom factors of up to 500x magnification, making for excellent viewing in continuous mode of complex PDF files and documents.This is as a result of the user-friendly JAVA interface and utility controls. JAVA binding: The complete JAVA bindings that come with Android PDF library allow for impeccable integration with Android Apps. ![]() These benefits are based on the advanced PDF engine, PDFNet PDF library. Plus, this can be done at a very high speed. Great PDF rendering on Android: Rendered PDFs are accurate, optimized, high quality and robust.They share the basic functionality of generating PDF documents, but PDF library goes on to offer editing, annotation, manipulation, viewing and rendering among other things. So what is the relationship between the two? Well, the Android PDF writer performs simple functions that can become more advanced in the Android PDF library. Relationship between Android PDF Library and Android PDF writer You can download it at your convenience for personal or organizational use. It is free, open-source software that will let you perform library tasks. While an Android PDF Library is a complex innovation from Android, An Android PDF writer (APW) is a simple Java library that enables users of Android devices that were released under the BSD license to generate simple PDF documents. An Android PDF Library is a high quality Android innovation with Java APIs that allows the developer and user to seamlessly integrate PDF generation or creation, annotation, searching, manipulation, viewing, rendering and printing of PDF files in Android.
