Title: Best way to save a screenshot
Post by: Haze on March 31, 2019, 07:12:59 pm

Hi,

I'm trying to catch up with last SFML releases, and noticed that RenderWindow::capture is now deprecated:

Quote

Use a sf::Texture and its sf::Texture::update(const Window&) function and copy its contents into an sf::Image instead.

My use case is saving to a image file what is currently rendered on a render window.

Is the following code the best approach for SFML >= 2.4?

sf::Texture texture;
texture.create(render_window.getSize().x, render_window.getSize().y);
texture.update(render_window);
if (texture.copyToImage().saveToFile(filename))
{
    std::cout << "screenshot saved to " << filename << std::endl;
}
 

Also, this seems like quite a common task. Maybe it should be added in the wiki?

Looks correct to me.

The Wiki is a community driven Wiki, would be great if you could add it! :)

Thanks for the confirmation.

I've added an entry to the Github wiki, under "Tutorials" section.

Nice to see all the core team is still active btw (I haven't used SFML since 2.1 release I think).
