Graphics / Re: sf::Texture load from memory

« on: May 21, 2019, 01:34:00 am »

static const unsigned char embeddedImageData[] =
{
    /* content generated by one of the hundreds
        of programs that do it, or by your own small utility
       (doesn't take more than 10 lines of C++ code) */
};

texture.loadFromMemory(embeddedImageData, sizeof(embeddedImageData));

Example of code that generate such an array:

#include <fstream>
#include <iomanip>

int main(int argc, char** argv)
{
    std::ifstream in("image.png", std::ios_base::binary);
    std::ofstream out("header.hpp");

    out << "static const unsigned char embeddedImageData[] =" << std::endl;
    out << "{" << std::endl;
    do
    {
        out << "    ";
        for (int i = 0; (i < 20) && in; ++i)
            out << "0x" << std::hex << std::setw(2) << std::setfill('0') << in.get() << std::dec << ", ";
        out << std::endl;
    }
    while (in);
    out << "};" << std::endl;

    return 0;
}
 

Note that it can be more concise if you don't care about the pretty formatting.
(delete last 0xffffffff)

Merci beaucoup Laurent pour ce bou de code,  ca marche a merveille.
