Open Source C++ Library for Image Processing

Apply Image Filters, Create, Manipulate & Render Popular Images file formats using Free C++ API.

 

CImg Library is an open source library that provides useful features for loading, saving, displaying and processing various types of images inside C++ applications. The CImg is a very lightweight and user-friendly library. The good thing is that it avoids handling complex dependencies and library compatibility issues. It is made of a single header file CImg.h that must be included in your C++ source. It helps developers by performing complex image processing activities in just a few lines of code.

The API supports advanced features like handling 3D images, Transform images, image filtering, image animation, Image Binarization and more. CImg library is very portable & self-contained. It is can be easily used on different operating systems with ease. Moreover, it’s also very compatible with numerous C++ compilers such as Visual C++, ICC, G++, etc.

Getting Started with CImg

The CImg Library is available as .zip package which is platform-independent. It contains all the required files, along with various examples, which shows how to use the library functions and classes.

You need to add these two lines in your C++ source code, in order to be able to work with CImg.

Add these lines for CImg working

 #include "CImg.h" 
using namespace cimg_library 

Install CImg via git command

 git clone https://framagit.org/dtschump/CImg.git  
You can also install it manually; download the latest release files directly from the  GitHub repository.

C++ API to Create & Modify Images

CImg open-source library allows C++ developers to create and manipulate different types of images inside their own applications. It also supports how to handle image display and mouse events. First of all, you need to include the main and only header files of the CImg library. The good thing is the library reduces the developer's load by allowing them to write a very small amount of code. Please also note that the source will perfectly work on UNIX and Windows systems.

Image Filtering Support

CImg library provides support for the image filtering process. Sometimes we need to retrieve information about images and that’s where Image filtering is commonly used. The image filtering process is one of the most common methods to apply to images to retrieving information. Mostly, filters are used in image noise removal, computer image derivatives, image edge enhancement, Shape analysis and more.
