Thanks! This fixed the problem perfectly.

Bilinear filter. Good to know. I will try to get my graphics terms right. ^_^

Graphics / Image Feathering

« on: October 30, 2011, 12:03:01 am »

So I was just writing a simple program to display an image. My image is a pixel tile. I noticed when I run the program it looked a little fuzzy. I took a screenshot and took a closer look..

Original Image (Transparent Background):



Original Image Closeup (on white background so you can see the pixelness):



"Fuzzy" Image Closeup:



As you can see, the program apparently "feathered" my image, even though I just told it to directly display it. Below is my code:

Code: [Select]

#include <SFML/Graphics.hpp>

int main() {

    // Create the main window
    sf::RenderWindow App(sf::VideoMode(800, 600), "SFML Image Feathering");

    // Load a sprite to display
    sf::Image Img;
    if(!Img.LoadFromFile("image.png"))
        return EXIT_FAILURE;
    sf::Sprite Tile(Img);

    // Start the game loop
    while(App.IsOpened()) {
        // Process events
        sf::Event Event;
        while(App.GetEvent(Event)) {

            // Close window : exit
            if(Event.Type == sf::Event::Closed) {

                App.Close();

            }

        }

        // Clear screen
        App.Clear();

        // Draw the sprite
        App.Draw(Tile);

        // Update the window
        App.Display();

    }

    return EXIT_SUCCESS;
}


Is there a way to directly display the image? Thanks.
