PolarSSL is a light-weight cryptographic and SSL/TLS library written in C. PolarSSL makes it easy for developers to include cryptographic and SSL/TLS capabilities in their (embedded) applications with as little hassle as possible. Loose coupling of the components inside the library means that it is easy to separate the parts that are needed, without needing to include the total library. PolarSSL is written with embedded systems in mind and has been ported on a number of architectures, including ARM, PowerPC, MIPS, and Motorola 68000. The source is written to have very loose coupling, enabling easy integration of parts in other software projects. Very loosely coupled cryptographic algorithms for MD2, MD4, MD5, SHA1, SHA-256, SHA-512, AES, Camellia, DES, Triple DES, ARC3, and RSA are included.
Papyrus is a 2D C++ scenegraph (canvas) library that utilizes the cairo library to perform drawing operations. Similar canvas libraries are the Gnome Canvas, Diacanvas, and the QT Canvas. Numerous canvas primitives are available, including arcs, rectangles, polylines, and line markers. An optional companion library, Papyrusmm, provides a set of Gtkmm widgets which includes viewports (a canvas display widget similar to Gtk::DrawingArea) and other UI widgets related to drawing interfaces.
LibU is a multiplatform C library that comes under a BSD-style license. It includes many interdependent modules for accomplishing several tasks: memory allocation, networking and URI parsing, string manipulation, debugging, and logging in a very compact way, plus many other miscellaneous tasks. It has a small footprint (about 70KB for the default configuration), it is modular, and it has a multiplatform nature, making it an ideal candidate for embedded systems. KLone is an example of such usage.
The STX ExecPipe library provides a convenient C++ interface to execute child programs connected via pipes. It is a front-end to the system calls fork(), pipe(), select(), and execv() and hides all the complexity of these low-level functions. It allows a program to build a sequence of connected children programs with the input and output of the pipe sequence redirected to a file, string, or file descriptor. The library also allows custom asynchronous data processing classes to be inserted into the pipe or placed at the source or sink of the sequence.
jPDFProcess is a Java library to work with PDF documents which can be used to deliver customized PDF content to your users or to process and manipulate incoming PDF content. The library has a simple interface to work with PDF documents and is designed to be integrated easily and seamlessly into your PDF document workflow. jPDFProcess provides the functionality found in many other Qoppa Software libraries, including printing, setting permissions and security, creating and assembling documents, digital signing, working with form fields, extracting text, and more. It can work with PDF documents from files, URLs, and input streams, and can save documents to files and output streams, so it can serve documents from a J2EE application directly to a client browser without any temporary files. jPDFProcess is platform-independent, and can be used in any environment which supports Java.
jPDFText is a Java library to extract text from PDF documents. PDF documents can be processed to extract the textual content for archiving, storage, searching, or indexing. jPDFText is built on top of Qoppa's proprietary PDF technology, so there is no need for any third party software or drivers. Main Features: loading PDF documents from files, network drives, URLs, or input streams; extracting text; and extracting words as a vector of Strings. It is written entirely in Java, which allows your application to remain platform independent. There is no need to install or configure additional drivers or software when deploying.
jPDFPrint is a Java library which can load and print Acrobat PDF documents directly from your Java programs or applets with or without user intervention. It is built on top of Qoppa Software's proprietary PDF technology, so there is no need for any third party software or drivers. Simply call the library from your Java programs, and documents can be sent to the printer.
jPDFWriter is a Java class library to create PDF documents directly from Java programs without having to install any third party drivers or software. It emulates the standard Java classes to print and draw graphics to reduce the learning curve when using the library and reuse existing code. It can create PDF files in two ways: PDF files can be created directly using jPDFWriter's very simple API (simply create a PDFDocument object, create as many PDFPage objects as necessary, draw strings, graphics, or any other elements supported by Graphics2D to the pages, and save the document), or jPDFWriter can extend the standard Java PrinterJob to create PDF files as though printing to a physical printer. This allows reuse of existing printing code and lets an application decide, at runtime, whether to send the output to a printer or to a PDF file. PDF files can be saved to files on a disk, written to a java.io.OutputStream, or written directly to a javax.servlet.ServletOutputStream to show in a browser when working within a J2EE application server. jPDFWriter is written entirely in Java, so application portability and operating system independence are not compromised.
