I implemented CImg hello world that loads an image, display on a CImg window, and save it. The complete code is available on my github.
[code lang="cpp"]
include <iostream>
include <string>
include <CImg.h>
int main() { std::cout << "run CImg hello world..." << std::endl; cimg_library::CImg<unsigned char> img; std::string strFileInput = "lena.pgm"; std::string strFileOutput = "lena.bmp"; img = cimg_library::CImg<unsigned char>(strFileInput.c_str()); std::cout << "load " << strFileInput << "..." << std::endl; std::cout << "width = " << img.width() << std::endl; std::cout << "height = " << img.height() << std::endl; std::cout << "color = " << img.spectrum() << std::endl; img.display("Input image"); img.save_bmp(strFileOutput.c_str()); return 0; } [/code]
