Hey everybody,
First sorry for my bad English, but I try to give my best .
So.... I have a problem with drawing 2D images on my screen.
Here is a screenshot, in order that you can understand me better:
https://www2.pic-upload.de/img/33853706/problem.png

As you can see, my program draws the image on the screen, but it also
draws 2 white lines with an invisible space between the lines and the picture.
Can you please explain me, where do these lines and the space come from?
How can I fix this problem?
My Main class:
package Launcher;

import org.lwjgl.opengl.*;

import static Renderer.Renderer.*;

public class Main{

public Main(){
BeginSession();

while(!Display.isCloseRequested()){

DrawTexture(QuickLoad("1"), 25, 25, 500, 500);

Display.update();
Display.sync(60);
}

Display.destroy();
}

public static void main(String[] args){
new Main();
}

}

And renderer class:
package Renderer;

import static org.lwjgl.opengl.GL11.*;

import java.io.IOException;
import java.io.InputStream;

import org.lwjgl.LWJGLException;
import org.lwjgl.opengl.*;
import org.newdawn.slick.opengl.*;
import org.newdawn.slick.util.ResourceLoader;
public class Renderer{

public static final int WIDTH = 2048, HEIGHT = 1400;

public static void BeginSession(){
Display.setTitle("Test");
try{
Display.setDisplayMode(new DisplayMode(WIDTH, HEIGHT));
Display.create();
}catch(LWJGLException e){
e.printStackTrace();
}

        glMatrixMode(GL_PROJECTION);
        glLoadIdentity();
        glOrtho(0, WIDTH , HEIGHT, 0, 1, -1);
        glMatrixMode(GL_MODELVIEW);
        glEnable(GL_TEXTURE_2D);
        glEnable(GL_BLEND);
        glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
}

    public static void DrawTexture(Texture tex, float x, float y, float width, float height){
        tex.bind();
        glTranslatef(x, y, 0);
        glBegin(GL_QUADS);
        glTexCoord2f(0, 0);
        glVertex2f(0, 0);
        glTexCoord2f(1, 0);
        glVertex2f(width, 0);
        glTexCoord2f(1, 1);
        glVertex2f(width, height);
        glTexCoord2f(0, 1);
        glVertex2f(0, height);
        glEnd();
        glLoadIdentity();
    }
   
    public static Texture LoadTexture(String path, String fileType){
    Texture texture = null;
    InputStream in = ResourceLoader.getResourceAsStream(path);
    try {
texture = TextureLoader.getTexture(fileType, in);
} catch (IOException e) {
e.printStackTrace();
}
   
    return texture;
    }
   
    public static Texture QuickLoad(String name){
        Texture tex = null;
        tex = LoadTexture("res/" + name + ".jpg", "JPG");
        return tex;
    }

}
