- The ADG library (Automatic Drawing Generation) is a set of functions focused on automating the drawing of mechanical parts. It is not a CAD system but a library providing a non-interactive canvas where you can put common CAD entities such as paths, xatches and quotes, to create your technical drawings. The final result can be displayed inside a GTK+ widget or exported to any cairo available format, such as PostScript and PDF documents or PNG and SVG images.
- BRL-CAD includes an interactive geometry editor, parallel ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, image-processing and signal-processing tools.
- Chafa is a command-line utility that converts all kinds of images, including animated GIFs, into ANSI/Unicode character output that can be displayed in a terminal. It is highly configurable, with support for alpha transparency and multiple color modes and color spaces, combining selectable ranges of Unicode characters to produce the desired output. The core functionality is provided by a C library with a public, well-documented API.
- DataMelt (DMelt) is an environment for numeric computation, statistical analysis, data mining, and graphical data visualization on the Java platform. This Java multiplatform program is integrated with a number of scripting languages: Jython (Python), Groovy, JRuby, BeanShell. DMelt can be used to plot functions and data in 2D and 3D, perform statistical tests, data mining, numeric computations, function minimization, linear algebra, solving systems of linear and differential equations. Linear, non-linear and symbolic regression are also available. Neural networks and various data-manipulation methods are integrated using powerful Java API. Elements of symbolic computations using Octave/Matlab scripting are supported.
- G'MIC is a full-featured free software framework for image processing, distributed under the CeCILL license. It provides several different user interfaces to convert / manipulate / filter / visualize generic image datasets, ranging from 1d scalar signals to 3d+t sequences of multi-spectral volumetric images, thus including 2d color images.
- A command-line interface gmic, to use the G'MIC image processing features from a shell. In this setting, G'MIC may be seen as a friendly companion to the ImageMagick or GraphicsMagick software suites.
- A small, portable, thread-safe and multi-threaded, C++ image processing library libgmic, to be linked to third-party applications. Its simple API allows programmers to add all G'MIC features in their own software without much efforts (a C API is available as well).
- A plug-in gmic_gimp, to bring G'MIC capabilities to the image retouching software GIMP. More than 450 filters are already available, sorted by category (Artistic, Black & white, Colors, Contours, Deformations, Degradations, Details, Film emulation, Frames, Layers, Light & shadows, Patterns, Rendering, Repair, Sequences, etc.).
- A web service G'MIC Online, to allow users applying image processing algorithms on their images, directly from a web browser.
- A Qt-based interface ZArt, for real-time processing of video streaming coming from webcams or video files.
- A free Java chart library. JFreeChart supports pie charts (2D and 3D), bar charts (horizontal and vertical, regular and stacked), line charts, scatter plots, time series charts, high-low-open-close charts, candlestick plots, Gantt charts, combined plots, thermometers, dials and more. JFreeChart can be used in applications, applets, servlets and JSP. JFreeChart's extensive feature set includes: - a consistent and well-documented API, supporting a wide range of chart types; - a flexible design that is easy to extend, and targets both server-side and client-side applications; - support for many output types, including Swing components, image files (including PNG and JPEG), and vector graphics file formats (including PDF, EPS and SVG); - JFreeChart is free software. It is distributed under the terms of the GNU Lesser General Public Licence (LGPL), which permits use in proprietary applications.
- KiCad is electronic design automation (EDA) software made for designing schematics of electronic circuits and printed circuit boards (PCB). KiCad is developed by the KiCad Developers Team, and features an integrated environment with schematic capture, bill of materials list, PCB layout and much more. KiCad is cross-platform, written with WxWidgets and runs on FreeBSD, Linux, Microsoft Windows and Mac OS X. A lot of component libraries are available. Also migrating tools for components are available (from other EDA software tools). File formats are plain text and well documented, which is good for CVS or Subversion and to make automated component generation scripts. Multiple languages are supported, such as English, Portuguese, Spanish, Czech, Polish, French, German, and Russian. The 3D PCB viewer use 3D model from Wings3D CAD.
- A collection of routines to create and manipulate PNG format graphic images. Designed as a replacement for GIF (and to a lesser extent TIFF) due to functional and patent problems, with more efficient compression (using Gzip-like DEFLATE), support for 24-bit color and alpha transparency.
- 'libtiff' provides support for the Tag Image File Format (TIFF), a widely used format for storing image data. This package includes a library (libtiff) for reading and writing TIFF, a small collection of tools for doing simple manipulations of TIFF images and documentation on the library and tools. A small assortment of TIFF-related software that has been contributed by others is also included. The library, along with associated tool programs, should handle most of your needs for reading and writing TIFF images on 32- and 64-bit machines.
