The Big Faceless Java PDF Viewer is a Swing component that can display PDF documents. It is intended for developers who don't require the full API. The PDF Viewer can be installed as an applet, an application, via Java Web Start, or embedded in a Swing application. Printing, saving, text search, forms, digital signatures, and annotations are some of the many features available. The viewer can be tailored to include just the features you need, and is a cost-effective solution for those needing the features of Adobe Acrobat on a Java platform.
jPDFSecure is a Java library which can digitally sign PDF documents and change security settings on PDF Documents. With jPDFSecure, your application or Java applet can encrypt PDF documents, set permissions and passwords, and create and apply digital signatures. jPDFSecure is optimized for performance and is built on top of Qoppa's proprietary PDF technology, so there is no need for any third party software or drivers. jPDFSecure has a simple interface to load PDF documents from files, network drives, URLs, and even input streams, which can be generated at runtime or come directly from a database. After changing security settings, jPDFSecure can save the document to a file, a java.io.OutputStream, or a javax.servlet.ServletOutputStream when running in a J2EE application server to output the file directly to a browser. jPDFSecure is platform-independent and can be used in any environment which supports Java.
jPDFFields is a Java library for working with interactive PDF forms in both AcroForm and XFA formats. It allows your application to get and set field values, and can import and export to the FDF, XFDF, and XDP formats. It can also "flatten" fields in a document. (Flattening is the process of merging the fields into the PDF content layer so the information is retained, but as static PDF content.) jPDFFields is built on top of Qoppa's proprietary PDF technology, so it is 100% Java and does not require any third party software or drivers.
PDF Studio is an easy to use yet powerful PDF editor. It maintains full compatibility with the PDF format and supports most PDF functions. It allows you to view, print, and search PDF files, review and annotate documents with text, graphics, and sound, scan to PDF, fill in and save forms, secure documents with passwords and permissions, merge, split, and assemble documents, convert Word, image, and text files to PDF, and add bookmarks, watermarks, headers, and footers. It is integrated with Google Apps and Sharepoint. The Pro version allows content editing, permanent manual redaction, batch processing, precision measuring tools, digital signatures, and preflight PDFs with PDF/X profiles.
Whyteboard allows you to annotate PDF and PostScript documents and various image formats. You can draw with common tools such as a pen, rectangle, ellipse, text tool, etc. You can draw shapes, which can be moved, resized, recoloured, etc. Your drawing history is stored, allowing you to replay it. Tabbed painting is supported, with each sheet having its own unlimited undo and redo operations. There are live-updating thumbnails for each sheet. Sheets that are closed can also be undone, restoring their data. Note controls, similar to virtual, editable Post-It Notes. A draggable, live-updating resizable canvas that stretches to whatever size you want.
