JHeatChart is a one class Java API for generating heat map charts that was created because very few charting APIs seem to contain the facility to create heat maps. It is not a full featured charting API and cannot be used to other charts. The generated charts are created as Java Image objects, which can be incorporated into a GUI or saved to a file.
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.
The Mirror C++ reflection library provides both compile-time and run-time meta-data describing common C++ program constructs like namespaces, types, enumerations, classes, their base classes and member variables, constructors, etc. and provides generic interfaces for their introspection. It also provides several high-level utilities based on the reflected meta-data like a factory generator, which generates, at compile-time, implementations of object factories which can create instances of arbitrary 'reflectable' type.
ntdisp, short for NtD In System Programming, is a system for programming LPC and STM32 (and possibly other) embedded devices. It provides three different frontends, a GObject-based library (for developers), a commandline utility (for computer geeks), and a GTK+3 frontend (for less geeky users).
