https://raw.githubusercontent.com/GreycLab/CImg/add2c47fb53ebed2ceaea628cc996c4f474cc282/Licence_CeCILL_V2-en.txt -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | ![Logo](http://cimg.eu/img/logo_header.jpg) 2 | ##### http://cimg.eu 3 | 4 | ------------------ 5 | ![Build](https://github.com/GreycLab/CImg/workflows/Build%20then%20test/badge.svg) 6 | ------------------ 7 | The **CImg Library** is a **small** and **open-source** **C++ library** for **image processing**, designed with these properties in mind: 8 | 9 | ![Usefulness](http://cimg.eu/img/item_usefulness.jpg) **CImg** defines *classes* and *methods* to manage images in your own C++ code. You can use **CImg** to load/save various file formats, access pixel values, display/transform/filter images, draw primitives (text, faces, curves, 3d objects, ...), compute statistics, manage user interactions on images, and so on... 10 | 11 | ![Genericity](http://cimg.eu/img/item_genericity.jpg) **CImg** defines a single image class able to represent datasets having up to *4-dimensions* (from 1d scalar signals to 3d hyperspectral volumetric images), with *template pixel types* (`bool,char,int,float,...`). It also handles image *collections* and *sequences*. 12 | 13 | ![Portability](http://cimg.eu/img/item_portability.jpg) **CImg** is *self-contained*, *thread-safe* and *highly portable*. It fully works on *different operating systems* (`Unix,Windows,MacOS X,*BSD,...`) and is compatible with *various C++ compilers* (`Visual C++,g++,clang++,icc,...`). 14 | 15 | ![Simplicity](http://cimg.eu/img/item_simplicity.jpg) **CImg** is *lightweight*. It is made of a single header file [`CImg.h`](https://github.com/GreycLab/CImg/raw/master/CImg.h) that must be included in your C++ source. It defines only *four* different classes, encapsulated in the namespace `cimg_library`. It can be compiled using a minimal set of standard C++ and system libraries only. *No need for exotic or complex dependencies*. 16 | 17 | ![Extensibility](http://cimg.eu/img/item_extensibility.jpg) Although not mandatory, **CImg** can use functionalities of external tools/libraries such as [Board](http://libboard.sourceforge.net/), [FFMPEG](http://ffmpeg.mplayerhq.hu/), [FFTW3](http://www.fftw.org/), [GraphicsMagick](http://www.graphicsmagick.org/), [ImageMagick](http://www.imagemagick.org/), [Lapack](http://www.netlib.org/lapack/), [libcurl](http://curl.haxx.se/libcurl/), [libjpeg](http://www.ijg.org/), [libpng](http://www.libpng.org/pub/png/libpng.html), [libtiff](http://www.libtiff.org/), [Magick++](http://www.imagemagick.org/Magick++/), [OpenEXR](http://www.openexr.com/), [OpenCV](http://http://opencv.willowgarage.com/wiki/), [OpenMP](http://www.openmp.org/) or [XMedCon](http://xmedcon.sourceforge.net/). Moreover, a simple *plug-in* mechanism allows any user to directly enhance the library capabilities according to their needs. 18 | 19 | ![Freedom](http://cimg.eu/img/item_freedom.jpg) **CImg** is a *free, open-source library* distributed under the [*CeCILL-C*](http://www.cecill.info/licences/Licence_CeCILL-C_V1-en.txt) (close to the GNU LGPL) or [CeCILL](http://www.cecill.info/licences/Licence_CeCILL_V2-en.txt) (compatible with the GNU GPL) licenses. It can be used in commercial applications. 20 | 21 | ------------------ 22 | 23 | > **CImg** stands for **Cool Image** : It is _easy to use_, _efficient_ and is intended to be a very pleasant toolbox to design image processing algorithms in C++. Due to its generic conception, it can cover a wide range of image processing applications. 24 | 25 | ------------------ 26 | -------------------------------------------------------------------------------- /examples/fade_images.cpp: -------------------------------------------------------------------------------- 1 | /* 2 | # 3 | # File : fade_images.cpp 4 | # ( C++ source file ) 5 | # 6 | # Description : Compute a linear fading between two images. 7 | # This file is a part of the CImg Library project. 8 | # ( http://cimg.eu ) 9 | # 10 | # Copyright : David Tschumperlé 11 | # ( http://tschumperle.users.greyc.fr/ ) 12 | # 13 | # License : CeCILL v2.0 14 | # ( http://www.cecill.info/licences/Licence_CeCILL_V2-en.html ) 15 | # 16 | # This software is governed by the CeCILL license under French law and 17 | # abiding by the rules of distribution of free software.

27 | You have different ways to get the Library: 28 |

29 | 30 | 31 | 35 | 43 | 47 | 58 |
32 | Standard Package
36 | The Library is mainly provided as 37 | 38 | .zip package 39 | which is platform-independent. 40 | It contains all the required files, as well as various examples (which must be compiled), 41 | illustrating the use of the library functions and classes.
42 |
44 | Sources Repository
48 | You may be also more adventurous and try the current development version with git. 49 | This ensures you will get the latest code available, and will ease the 50 | updates as well. To do this, just 51 | type the command : 52 |
53 | git clone --depth=1 https://github.com/GreycLab/CImg.git 54 |
55 | in your favorite console. Nevertheless, you have to know that some code in the source repository 56 | is under development and may be experimental, so always test the latest stable archive before complaining ! 57 |
