DIPlib 3

Build Status Language grade: C/C++

The DIPlib project contains:

  • DIPlib, a C++ library for quantitative image analysis. It has been in development at Delft University of Technology in The Netherlands since 1995. The 3.0 release of DIPlib represents a complete rewrite in modern C++ of the library infrastructure, with most of the image processing and analysis algorithms ported from the previous version, and some of them improved significantly. Many of the improvements to DIPlib are a result of porting over concepts and ideas first implemented in DIPimage. Read the DIPlib documentation.

  • DIPimage, a MATLAB toolbox for quantitative image analysis. It has been in development at Delft University of Technology in The Netherlands since 1999. Read the DIPimage User Manual.

  • PyDIP, Python bindings to DIPlib. This is currently a thin wrapper that exposes the C++ functionality with little change. the PyDIP User Manual

  • DIPviewer, an interactive image display utility. It is usable from C++, Python and MATLAB programs. Within DIPimage this is an optional alternative to the default MATLAB-native interactive display utility. Read the DIPviewer documentation.

  • DIPjavaio, an interface to OME Bio-Formats, a Java-based library that reads hundreds of image file formats. This module is usable from C++ and Python. DIPimage has a different way of interfacing with Bio-Formats. Read the DIPjavaio documentation

See the DIPlib website for more information.

Building the library

Linux, MacOS, Cygwin and other Unix-like systems

To build the library you will need a C++14 compliant compiler and CMake. Use the following commands to build:

mkdir target
cd target
cmake /path/to/dip/root/directory
make -j install

For detailed instructions, see INSTALL.md.

Windows

Unless you want to use Cygwin or MinGW (see above), we recommend Microsoft Visual Studio 2019. You'll also need CMake.

Using CMake-gui, choose where the source directory is and where to build the binaries. Then press "Configure" and select Visual Studio. Finally, press "Generate". You should now have a Visual Studio solution file that you can open in Visual Studio and build as usual.

For step-by-step instructions, see INSTALL_Windows.md. See also INSTALL.md for additional information and optional dependencies you might want to install.

Linking against the library

When using CMake, and importing the DIP target into your project in the right way, you will just need to link against the DIP target and everything will be configured correctly. Otherwise, there are several macros that you should define when building any program that links against DIPlib:

If DIPlib was build with the DIP_SHARED_LIBRARY flag not set, then you need to define the DIP_CONFIG_DIP_IS_STATIC macro when compiling the code that links against it. Likewise, if the DIP_ALWAYS_128_PRNG flag was set, then you must define a DIP_CONFIG_ALWAYS_128_PRNG macro when compiling your program. Mismatching this flag could cause your program to not link, or worse, crash at runtime.

The following flags do not need to be matched, but they should be if you want the inline functions to behave the same as the pre-compiled ones:

  • flag: DIP_ENABLE_STACK_TRACE -- macro: DIP_CONFIG_ENABLE_STACK_TRACE
  • flag: DIP_ENABLE_ASSERT -- macro: DIP_CONFIG_ENABLE_ASSERT

Also, if your compiler supports __PRETTY_FUNCTION__, set the macro DIP_CONFIG_HAS_PRETTY_FUNCTION to get better stack traces.

For DIPviewer, if DIP_SHARED_LIBRARY was not set, define the DIP_CONFIG_DIPVIEWER_IS_STATIC macro. Also define DIP_CONFIG_HAS_FREEGLUT or DIP_CONFIG_HAS_GLFW depending on which back-end is used.

For DIPjavaio, if DIP_SHARED_LIBRARY was not set, define the DIP_CONFIG_DIPJAVAIO_IS_STATIC macro. Also define DIP_CONFIG_HAS_DIPJAVAIO.

Contributing

Reporting a bug

We use the issue tracker on GitHub to manage bug reports. See CONTRIBUTING.md for instructions on how to report a bug.

Bug fixes, algorithm improvements, new algorithms

Feel free to submit a pull request on GitHub. Please follow our style guide and make sure to read CONTRIBUTING.md first.

Documentation, tutorials

Documentation can always be improved (also, PyDIP has hardy any at all!). If you want to help write documentation, or create tutorials for how to use the library, read CONTRIBUTING.md, then submit a pull request on GitHub.

If you found an error in the documentation, we consider this a bug. See above how to report it.
