Hello everyone,
First of all please forgive my English as it is not my mother tongue
I'm trying to conceive a very simple code to begin with SFML : displaying an image, then, after a click on it, setting the pixel clicked color in blue.
Unfortunately, when I click, nothing happens and I have no idea why. I've displayed the pixels values (RGB) in the CLI before and after the click, I see that the values are different (so the color has been modified) but the picture isn't modified. So I think that the problem comes from my use of the update fonction. I have read the documentation several times and I still don't know what I am doing wrong.
Thanks in advance for any help !
You can find my code below :
sf::Image fill_shape(int x, int y, sf::Image img){
sf::Image new_image = img;
new_image.setPixel(x, y, BLUE);
return new_image;
}
int main()
{
// Load an image file from a file
sf::Texture texture;
if (!texture.loadFromFile("image.jpg")){
return EXIT_FAILURE;
}
sf::Sprite sprite(texture);
int x = sprite.getTexture()->getSize().x * sprite.getScale().x;
int y = sprite.getTexture()->getSize().y * sprite.getScale().y;
sf::RenderWindow window(sf::VideoMode(x, y), "Image Filler");
while (window.isOpen())
{
sf::Event event;
while (window.pollEvent(event))
{
if (event.type == sf::Event::Closed){
window.close();
}
else if (sf::Mouse::isButtonPressed(sf::Mouse::Left))
{
sf::Vector2i position = sf::Mouse::getPosition();
int x = position.x;
int y = position.y;
sf::Image image = sprite.getTexture()->copyToImage();
sf::Image new_image = fill_shape(x, y, image);
texture.update(new_image);
sprite.setTexture(texture);
}
}
window.clear();
window.draw(sprite);
window.display();
}
return 0;
}
