GraphicsMagick is a robust collection of tools and libraries which support reading, writing, and manipulating an image in over 90 major formats including popular formats like DPX, DICOM, BMP, GIF, JPEG, JPEG-2000, PDF, PNG, PNM, SVG, and TIFF. A high-quality 2D renderer is included, which provides a subset of SVG capabilities. C, C++, Perl, Tcl, and Ruby are supported. Originally based on ImageMagick, GraphicsMagick focuses on performance, minimizing bugs, and providing stable APIs and ABIs. It runs on all modern variants of Unix, Windows, and Mac OS X.
The Geospatial Data Abstraction Library (GDAL) is a unifying C/C++ API for accessing raster geospatial data, and currently includes formats like GeoTIFF, Erdas Imagine, Arc/Info Binary, CEOS, DTED, GXF, and SDTS. It is intended to provide efficient access, suitable for use in viewer applications, and also attempts to preserve coordinate systems and metadata. Python, C, and C++ interfaces are available.
Metakit is a small, portable database library using a hybrid relational / hierarchical data model with a column-wise internal storage format. For C++, include a single header file and 125 kb DLL or statically link directly. Ideal for desktops, embedded systems, smartphones, and PDAs. Bindings for Python and Tcl. A very mature, stable code base.
ImageVis3D is a volume rendering application specifically designed to render large data sets. This is achieved by splitting the data set into multiple levels of detail (LoD), with each level itself decomposed into multiple bricks (atomic rendering primitives). Interaction occurs at the coarsest LoD, which can be rendered instantaneously on almost all modern systems. After a configurable delay, ImageVis3D will successively render finer levels of detail, until the data are visible at their native resolution. Volume rendering, as the name implies, is a technique for rendering scalar volumes of data. The rendering method allows one to see "inside" a data set, allowing the user to understand the inner three-dimensional structure of the data.
C++ Resources Compiler is a tool that will generate a C++ source file (along with the corresponding header file) that embeds any given data file and provides a Resource class which gives access to this data. The Resource class can be created in two flavors: one using STL streams, the other using WxWidgets streams. Its function is similar to that of the "qtrc" tool from the Qt toolkit.
stdnoj is a cross-platform C++ class library that includes classes for using portable strings, databases, SMTP, POP, NNTP, arrays, files, directories, logging, email, and sockets. While templates are used, no reliance upon STL or other (traditionally error-prone) technologies has been used, which increases portability between compilers.
Gecode is a portable, accessible, and efficient environment for developing constraint-based systems and applications. Gecode is radically open for programming, meaning that it can be easily interfaced to other systems. It supports the programming of new propagators (as implementation of constraints), branching strategies, and search engines. New variable domains can be programmed at the same level of efficiency as finite domain and integer set variables that come predefined with Gecode.
The JThread package contains classes that represent a thread and a mutex. On a Unix-like platform, the pthread library is used as the underlying thread mechanism. On an MS Windows platform, Win32 threads are used. By using these wrapper classes, you can easily create applications that use threads without having to worry about which platform the program will be running on.
