Graphics / Converting Image to GLuint (a texture)

« on: August 31, 2009, 04:10:38 am »

Code: [Select]


GLuint ScreenImage()
    {
    sf::Image img;
    img.CopyScreen(App,sf::IntRect(0,0,512,256));
    const sf::Uint8* ptr = img.GetPixelsPtr();
    GLuint tex;
    glGenTextures(1, &tex);
    glBindTexture(GL_TEXTURE_2D, tex);
    glTexImage2D(GL_TEXTURE_2D,0,GL_RGBA,512,256,0,GL_RGBA,GL_UNSIGNED_INT,ptr);
    glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR);
    glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR);
    glBindTexture(GL_TEXTURE_2D, 0);
    return tex;
    }

what am I doing wrong?

General / Static Linking

« on: August 30, 2009, 07:06:13 pm »

yes but dynamic linking "boost" performance with Linux ( at least it doesn't decrease performances ) .

How would I do this, since there are no static libraries for linux. Would I just include the SFML source?

Is it possible to static link in Ubuntu 8.10?

Graphics / Can't load sf::Sprite from a function

« on: August 01, 2009, 05:30:13 pm »

Code: [Select]

#include <SFML/Graphics.hpp>
#include <string>
using namespace std;
sf::RenderWindow App;

sf::Sprite load_sprite(string path)
    {
    sf::Sprite test_sprite;
    sf::Image img;
    img.LoadFromFile(path);
    test_sprite.SetImage(img);
    return test_sprite;
    }

//#define fromFunction // Un-comment the #define to make the image load incorrectly.

#ifdef _WIN32
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
#else
int main()
#endif
    {
    App.Create(sf::VideoMode(640, 480, 32), "SFML Window");
    sf::Sprite spr;
    #ifdef fromFunction
        spr = load_sprite("image.bmp");
    #else
        sf::Image bobf;
        bobf.LoadFromFile("image.bmp");
        spr.SetImage(bobf);
    #endif
    spr.SetCenter(120,80);
    spr.SetScale(1,1);
    spr.SetColor(sf::Color(255,255,255));
    spr.SetX(320);
    spr.SetY(240);
    bool loopin = true;
    while(loopin)
        {
        sf::Event Event;
        while (App.GetEvent(Event))
            {
            if ((Event.Type == sf::Event::Closed) || ((Event.Type == sf::Event::KeyPressed) && (Event.Key.Code == sf::Key::Escape)))
                {
                App.Close();
                loopin = false;
                break;
                }
            }
        App.Draw(spr);
        App.Display();
        sf::Clock clock;
        clock.Reset();
        while(clock.GetElapsedTime() < 1/60)
            {}
        }
return EXIT_SUCCESS;
    }
Output when fromFunction is defined

Output when fromFunction is NOT defined


edit:
fixed something. but the problem still occurs
