Strings edit is a library that provides I/O facilities for integers, floating-point numbers, Roman numerals, and strings. Both input and output subroutines support string pointers for consequent stream processing. The output can be aligned in a fixed size field with padding. Numeric input can be checked against expected values range to be either saturated or to raise an exception. For floating-point output either relative or absolute output precision can be specified. UTF-8 encoded strings are supported, including wildcard pattern matching, sets and maps of code points, upper/lowercase, and other Unicode categorizations.
JGraph is a free, mature, and robust Java diagramming library. It contains all the graph visualization, layout, and interaction functionality you might expect in a graph library, including multiple views, layering, zoom, drag and drop, undo, automatic expanding and collapsing, routing, and layouts. You can create workflow editors, BPMN, CAD tools, network diagrams, database visualization tools, and more. It is fully documented, including examples, and has an active support community.
Qanava is a C++ library designed to display graphs on a Qt canvas. Qanava provide classes to generate various layouts of directed graphs and visualize their nodes with custom styles on a graphic canvas. Qanava is designed for applications with basic graph visualization needs such as Gantt charts, social networks, and document or network modelling applications. It is not meant for a complex interactive visualization of very large data sets.
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.
JGraph Layout Pro is a high performance graph layout library for JGraph that automatically positions your graph, diagram, or network in a visually pleasing manner. Layout Pro provides flexibility and a simple design, enabling you to use circular, tree, force-directed, and hierarchical layouts with ease. Example uses are organisational charts, workflow and process diagrams, call charts, network diagrams, UML tools, and more. It comes with its own documentation and an example applet.
bit is a library that makes it easier to dynamically manipulate data buffers containing fields that do not have octet (byte) boundaries. An example is the IP header, which is generally dealt with at compile time via bit fields in a structure. A key feature of the bit library is support for loading data formats described in XML files and dynamically parsing those fields at run time. This library was initially created to support reading various kinds of robotic device I/O (IR sensors, motors), but it has also been used for run time parsing of IP, TCP, UDP, and RTP headers.
reacTIVision is a computer vision framework for the fast and robust tracking of fiducial markers attached to physical objects, as well as for multi-touch finger tracking. It was mainly designed as a toolkit for the rapid development of table-based tangible user interfaces and interactive multi-touch surfaces such as the reacTable. Client application examples are available for various programming environments such as C++, Java, C#, Processing, PureData, Max/MSP, and Quartz Composer.
JGraphpad Pro is a complete application framework for rapid development of JGraph tools. It is meant for developers who wish to provide a stand-alone, rich-client graph application. The user interface is configurable with XML, and it uses a plugin architecture for extra functionality. It features a wide range of application components like palette, overview, the ability to export to many image and XML formats, copy and paste, drag and drop, rich text labels, database or backend connectivity, and visual complexity management. You can use it to create workflow editors, call graphs, CAD tools, network diagrams, database visualization tools, and more.
