 # CppBMPLoader
-An exhaustive BMP Loader, MIT-licensed, implemented for c11 and c20

+## Genesis of this project
+The genesis of this project is the initial creation of the **OGLFW** library, 
+an object overlay of the **GLFW** library, and the need to associate it with 
+a library for loading images under the **MIT license** or from the public 
+domain, free of rights, to associate them with icons provided in OGLFW. 
+
+Being unable to find such a library under this type of license, a solution 
+was to let users of the original **OGLFW** library load the images themselves 
+using the external library of their choice, even if not under the MIT license.
+
+Another solution was to propose an `Icon` class with a virtual image loading 
+method not implemented in this base class. This second solution allowed users 
+to derive their own classes from this Icon base class and to implement the 
+image loading method corresponding to the format of the images to be loaded 
+(possibly using already existing but less permissively licensed libraries). 
+To this end, and as an example of implementation, a `BMPIcon` derived class 
+has been provided in the **OGLFW** library. Its implementation had to rely on 
+an external library which allows the loading of **BMP** images. Unfortunately, 
+no library met the required licensing criteria or, when unlicensed or under 
+**MIT** license, did not allow decoding of all cases of BMP image encoding.
+
+The **CppBMPLoader** library therefore fills this gap by offering the only 
+loading of **BMP** images in all the forms that this image format allows and 
+under the permissive MIT license. It will also meet many other needs when we 
+see the quantity of questions asked on this subject on the Internet and the 
+number of BMPLoader libraries already existing but apparently incomplete that 
+we can find on *GitHub*, programmed in c++ or in other programming languages.
+
+Initially, two versions of the library are offered, one responding to standard 
+c++11 of the programming language and the other responding to standard c++20 
+and offering more advanced programming concepts (e.g. programmed in the form 
+of c++ modules ).
+
+Notice: by April and May 2024, this original library **OGLFW** is still under 
+development.
