SFML updateTexture error

[MenosGrandes]

Im on Windows 8.1 with MinGw32 4.8.1-4 using SFML 2.1. Because all precompiled versions don't work, but it's not the point.

I have

    m_pixels = new Colour[width*height];
 

where Colour have     

 unsigned char r,g,b,a;

Now I'm trying to rewrite all pixels from m_pixels to   

 sf::Uint8 * pixels = new sf::Uint8[img_size.x*img_size.y*4];
 

using

void RenderTarget::rewritePixelForTexture(d_type::Bubyte* pixels)
{
    for (d_type::Bint i=0; i<m_size.x*m_size.y ; i++)
    {
        d_type::Bint k=i*4;
        pixels[k+3]=m_pixels[i].a;
        pixels[k+2]=m_pixels[i].r;
        pixels[k+1]=m_pixels[i].g;
        pixels[k]  =m_pixels[i].b;

    }

}

Whole main.cpp :

sf::RenderWindow window(sf::VideoMode(img_size.x, img_size.y), "RENDERER!");

    sf::Texture texture;
    if (!texture.create(img_size.x, img_size.y))
    {
        std::cout<<"ERROR WITH TEXTURE\n";
    }

    sf::Sprite sprite(texture);

    sf::Uint8 * pixels = new sf::Uint8[img_size.x*img_size.y*4];
    sf::Clock FPSClock;
    std::stringstream ss;
    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }


        file->rewritePixelForTexture(pixels);
        texture.update(pixels);

        window.clear();
        window.draw(sprite);

        window.display();

        ss<<getFPS(FPSClock.restart());

       window.setTitle(ss.str());
       ss.str("");


    }

And now to the core. This program supose to be softwere renderer, so NOT USING OPENGL\DIRECTX to render objects. I'm using the SFML only for window. And I have class to draw to file, simple TGA

void RenderTarget::drawToFile(std::string m_filename)
{
    //Error checking
    if (m_size.x <= 0 || m_size.y <= 0)
    {
        std::cout << "Image size is not set properly\n";
        return;
    }

    std::ofstream o(m_filename.c_str(), std::ios::out | std::ios::binary);

    //Write the header
    o.put(0);
    o.put(0);
    o.put(2);                         /* uncompressed RGB */
    o.put(0);
    o.put(0);
    o.put(0);
    o.put(0);
    o.put(0);
    o.put(0);
    o.put(0);           /* X origin */
    o.put(0);
    o.put(0);           /* y origin */
    o.put((m_size.x  & 0x00FF));
    o.put((m_size.x & 0xFF00) / 256);
    o.put((m_size.y  & 0x00FF));
    o.put((m_size.y  & 0xFF00) / 256);
    o.put(32);                        /* 24 bit bitmap */
    o.put(0);

    //Write the pixel data
    for (d_type::Bint i=0; i<getSizePixels() ; i++)
    {
        o.put(m_pixels[i].b);
        o.put(m_pixels[i].g);
        o.put(m_pixels[i].r);
        o.put(m_pixels[i].a);
    }

    //close the file
    o.close();
}

And this is the resault. The triangle is in position:

Vector3Bf(0,0,0),Vector3Bf(0.5f,0.5f,0),Vector3Bf(0.5f,0,0)

But the file and the Texture/Sprite are different.

And my question is simple.. WHY?....

Obviously, the triangle is upside-down and R/B color channels are swapped. So either change something in the file header, or swap pixels lines and R/B components when you write them.

[MenosGrandes]

Dispise the colors, why the triangle is upside down?

I don't know, it's your job to find out this kind of stuff It's either your own code that inverts rows, or the TGA format that doesn't use the same convention than SFML. Check by yourself.

Point (0,0,0) is in the center of the view space. The Triangle in TGA is correctly drawn, but when I'm rewriting the data to the SFML the texture flip out..
