Creating image with Boost.GIL

Question

I\'ve been trying to read the boost::gil documentation, but it\'s somewhere between lacking, and convoluted.

Ranting aside, I need an example on how to do the follow

Answer 1

I haven't used GIL yet, but I want to learn it as well. Having looked at the design guide and having googled up the error related to libpng, looks like the simplest example is

#define png_infopp_NULL (png_infopp)NULL
#define int_p_NULL (int*)NULL
#include <boost/gil/gil_all.hpp>
#include <boost/gil/extension/io/png_dynamic_io.hpp>
using namespace boost::gil;
int main()
{
    rgb8_image_t img(512, 512);
    rgb8_pixel_t red(255, 0, 0);
    fill_pixels(view(img), red);
    png_write_view("redsquare.png", const_view(img));
}

works for me, with -lpng on command line, producing this image
