Title: blurry png and bmp sprite
Post by: kaikimi on September 21, 2010, 05:41:26 pm

I'm trying to learn SFML and I've made a small program that just displays a sprite. It seems the sprite is rather blurry though. The result is the same if i use a bmp or png.

here's a screenshot

here's my source
Program.cs

Code: [Select]

using System;
using SFML;
using SFML.Window;
using SFML.Graphics;

namespace SFMLTest
{
    class Program
    {
        public Player MyPlayer;

        static void OnClose(object Sender, EventArgs e)
        {
            RenderWindow Window = (RenderWindow)Sender;
            Window.Close();
        }

        static void Main(string[] args)
        {
            RenderWindow Window = new RenderWindow(new VideoMode(384,256),"Hello world!");
           
            Window.Closed += new EventHandler(OnClose);
            Window.KeyPressed += new EventHandler<KeyEventArgs>(OnKeyPressed);

            while(Window.IsOpened())
            {
                Window.DispatchEvents();
                Window.Clear();
               
                Player MyPlayer = new Player();
                Player.Initialize(MyPlayer);

                Sprite ImageToDraw = MyPlayer.Draw(MyPlayer);

                Window.Draw(ImageToDraw);

                Window.Display();
            }
        }

        static void OnKeyPressed(object Sender, KeyEventArgs e)
        {
            RenderWindow Window = (RenderWindow)Sender;
            if (e.Code == KeyCode.Escape)
                Window.Close();
        }
    }
}


Player.cs

Code: [Select]

using System;
using SFML;
using SFML.Window;
using SFML.Graphics;

namespace SFMLTest
{
    class Player
    {
        public int X,Y;
        public string ImagePath;

        public Player()
        {
        }

        public static void Initialize(Player Player)
        {
            Player.X = 100;
            Player.Y = 100;
            Player.ImagePath = "Images/TestImage.png";
        }

        public Sprite Draw(Player Player)
        {
            Sprite PlayerImage = new Sprite(new Image(Player.ImagePath));
            PlayerImage.Position = new Vector2(Player.X,Player.Y);
            return PlayerImage;
        }
    }
}

Call SetSmooth(false) on your image to disable linear filtering.

Thanks, I didn't realize there was a property for that.

I am having a similar problem, but with fonts.  What do I do?

It's not a problem, fonts look very bad when smoothing is turned off so it's always on.

maybe with the bigger fonts, but this one is very small and it looks funny when some of the pixels are grey.

Dunno whether something has been done to prevent this on SFML's side now but... some time ago I remember that text looked blurred because I wasn't drawing it on integer coordinates. Make sure you're not asking SFML to draw your text on half pixels.
