Texture not filling entire quad

Question

I have configured most of it to the letter of the slick tutorials but what I get is the png in the lower left corner filling only 3/4 of the quad the dimensions are 100x100 for the quad and the texture is to fill it entirely but for some reason I cant get wrapping to work(HELP!! if that is my mistake)

Code for registry:

public Form(String fileName, Frame frame) {
    try {
        texture = TextureLoader.getTexture(
                "PNG",
                ResourceLoader.getResourceAsStream("img/" + fileName
                        + ".png"));
    } catch (IOException e) {
        e.printStackTrace();
    }
    this.frame = frame;
    VectorFrame = a.constructVectorFrame(frame);
}

And the code for the rendering:

    GL11.glEnable(GL11.GL_TEXTURE_2D);
    Color.white.bind();
    texture.bind();
    GL11.glBegin(GL11.GL_QUADS);
    GL11.glTexCoord2f(0, 0);
    GL11.glVertex2d(point.x, point.y);
    GL11.glTexCoord2f(0, 1);
    GL11.glVertex2d(point.x, point.y + frame.maxY);
    GL11.glTexCoord2f(1, 1);
    GL11.glVertex2d(point.x + frame.maxX, point.y + frame.maxY);
    GL11.glTexCoord2f(1, 0);
    GL11.glVertex2d(point.x + frame.maxX, point.y);
    GL11.glEnd();
    GL11.glDisable(GL11.GL_TEXTURE_2D);

    a.renderVectorFrame(point, VectorFrame);

Answer 1

Slick forces you to use power-of-two textures. You have two ways to deal with this:

• use power-of-two textures (for example, 128x128)
• change the 1.0fs inside your glTexCoord2f() to width/(nearest power of 2) and height/(nearest power of 2)

Also, look at this SO question: Texture doesn't stretch properly. Why is this happening?

Here is a easy way to do it. Use texture.getWidth()/getHeight() when setting the TextureCoordinates. Works perfectly for me

GL11.glEnable(GL11.GL_TEXTURE_2D);
Color.white.bind();
texture.bind();
GL11.glBegin(GL11.GL_QUADS);
GL11.glTexCoord2f(0, 0);
GL11.glVertex2d(point.x, point.y);

GL11.glTexCoord2f(0, texture.getHeight()); // <---

GL11.glVertex2d(point.x, point.y + frame.maxY);

GL11.glTexCoord2f(texture.getWidth(), texture.getHeight()); // <---

GL11.glVertex2d(point.x + frame.maxX, point.y + frame.maxY);

GL11.glTexCoord2f(texture.getWidth(), 0); // <---

GL11.glVertex2d(point.x + frame.maxX, point.y);
GL11.glEnd();
GL11.glDisable(GL11.GL_TEXTURE_2D);

a.renderVectorFrame(point, VectorFrame);
