first
black=none = 297KB
Transparent = 330KB(Transparent is supported in sfml window)
second
i try with bmp
original 24 88KB(painted in paint)

2 - not supported
16 original 15KB screenshot 88KB
24 original 88KB screenshot 88KB
256 original 31KB screenshot 88KB

so sfml suport only 24 bmp
what compression used in sfml?

image weight

(click to show/hide)

//this program open "image.png" and save screenshot "screenshot.png"
//to make screenshot press left arrow
#include <SFML/Graphics.hpp>

int main()
{
sf::Texture texture;
if (!texture.loadFromFile("image.png")){return 0;}

//windows size = texture size because i want to copy whole image

sf::Vector2u WindowSize = texture.getSize();
sf::RenderWindow window(sf::VideoMode(WindowSize.x,WindowSize.y), "SFML works!",sf::Style::Close);

sf::Image screenshot;

sf::Sprite sprite;
sprite.setTexture(texture);




    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();

            if (sf::Mouse::isButtonPressed(sf::Mouse::Left))
                {
                screenshot = window.capture();
                screenshot.saveToFile("Screenshot.png");
                }
        }



 window.clear(sf::Color::Transparent);
 window.draw(sprite);
 window.display();
    }
    return 0;
}

black image + if you minimize a window it turns black or white

(click to show/hide)

int main()
{
sf::Texture texture;
if (!texture.loadFromFile("image.png")){return 0;}

//windows size = texture size because i want to copy whole image

sf::Vector2u WindowSize = texture.getSize();
sf::RenderWindow window(sf::VideoMode(WindowSize.x,WindowSize.y), "SFML works!",sf::Style::Close);

sf::Image screenshot;

sf::Sprite sprite;
sprite.setTexture(texture);


 window.clear(sf::Color::Transparent);
 window.draw(sprite);
 window.display();

screenshot = window.capture();                  //<<<<<<<<<<
screenshot.saveToFile("Screenshot.png");        //<<<<<<<<<<

    return 0;
}

i tested it on this image https://en.wikipedia.org/wiki/Portable_Network_Graphics#/media/File:PNG_transparency_demonstration_1.png
original: 214 KB
screenshot: 330KB

Network / Re: Can sfml open Port (computer networking) in firewall?

What are you trying to achieve anyways?

1. i want to create client which could share game files like maps and models with another client.
2. for easy server setup

No and Steam.doesn't do anything. Usually if you try to open a port the Windowa firwall will complain on its own and you can accept or deny.

What about uTorrent?

I'm familiar with the term "open a port" in connection with firewall configuration. But this has nothing to do with SFML, so I assume you mean what Jesper mentioned, namely "open a socket and connect it to a port".

As you see by our guesses, repeating only the thread title in the post is not the best way of explaining the problem.

Can sfml open Port (computer networking) in firewall(like Windows Firewall), NOT SOCKET. And how progams like steam do it?

it would be useful to manage files. I think it will make game more portable(find save files and etc).
