sfml resize image code example

Example: sfml resize image

/*
sf::Image newImage = sf::Image();
newImage.create(50, 50); // set size
resizeImage(OldImage, newImage);

*/

void resizeImage(const sf::Image& originalImage, sf::Image& resizedImage)
{
    const sf::Vector2u originalImageSize{ originalImage.getSize() };
    const sf::Vector2u resizedImageSize{ resizedImage.getSize() };
    for (unsigned int y{ 0u }; y < resizedImageSize.y; ++y)
    {
        for (unsigned int x{ 0u }; x < resizedImageSize.x; ++x)
        {
            unsigned int origX{ static_cast<unsigned int>(static_cast<double>(x) / resizedImageSize.x * originalImageSize.x) };
            unsigned int origY{ static_cast<unsigned int>(static_cast<double>(y) / resizedImageSize.y * originalImageSize.y) };
            resizedImage.setPixel(x, y, originalImage.getPixel(origX, origY));
        }
    }
