I'm looking for comand to take a screenshot with SFML 2.0
The App.Capture of 1.6 doesn't work in 2.0 and i didn't find the good comand to do it.
I need to make a menù with last frame of the game under it.
So i want to do this
Take screen-> take it in memory -> use the comande Image.LoadFromMemory -> show it under menu interface.
Can i do it?

A question... i want to save my screenshot by numbers
Ex: screen001,screen002 etc.
I made this code but i don't know how to put into SaveToFile()_

Code: [Select]


char screen[50];
int numScreen=4;
sprintf (screen, "%03d", numScreen);

So if i do cout << screen; i get 004 etc.
Can you help me?

If you're programming c++, you should use c++

.

I recommend std::stringstream to you. It should look like this:

Code: [Select]


std::stringstream filename;
filename << "screenshots/screenshot_" << screenshot_num_ << ".png";
Image.SaveToFile( filename.str() );

There's probably a better way to do it, but the first thing that comes to mind is ...

Code: [Select]

If screenshot button pressed
    takeScreenshot = true

//Drawing stuff
if !takeScreenshot
    draw FPS

blah blah

if takeScreenshot
    take screenshot

I am rather tired so sorry if this is impossible/stupid/doesn't work

The problem is that FPS shown on screen is not from game... is from a third-party program (Fraps/Play Claw etc). I don't know why it capture this overlay too, but i can't find a solution to isolate it

It is called "screenshot". Hence it captures what's on the screen. And the overly is on the screen, hence it is captured

.
The easiest way would probably be not to use these FPS-applications, if you want to create a screenshot.

Uhm but there are some games that doesn't capture FPS

(I've just take some screenshots in Portal 2)

They probably write some windows specific code to omit that. Not something you can do purely trough SFML. I recommend instead that you have your own FPS overlay built into the application. And any other debug information you might need.
