Graphics / How to convert my PixelArray ?

« on: October 03, 2014, 06:40:26 pm »

Hello everyone, I've a project where I have to compress an image. Everything is ok except the displaying of the image (after decompression).
To have my pixelArray, I made:

struct Pixel
{
        uint8_t B, G, R;
};

Pixel** pixelArray = new Pixel*[bmpHeader.ImageWidth];
        for (int i = 0; i < bmpHeader.ImageWidth; ++i)
                pixelArray[i] = new Pixel[bmpHeader.ImageHeight];
 

Do not care about what is bmpHeader, that just give the size of the image.

Now I would like to display it with SFML, I think texture.update() would work fine but I don't know how to convert Pixel** to sf::Uint8*, and are we oblige to use rbga ? (because I don't use transparency)

Can you please tell me how  sf::Uint8* works ? Or even better, can you guide me to convert Pixel** to  sf::Uint8* ?

Thanks a lot !
