What's wrong here?:
public int load(String imagepath) {
BufferedImage bi;
try {
bi = ImageIO.read(new File(imagepath));
width = bi.getWidth();
height = bi.getHeight();
int[] pixels_raw = new int[width * height * 4];
pixels_raw = bi.getRGB(0, 0, width, height, null, 0, width);
ByteBuffer pixels = BufferUtils.createByteBuffer(width * height * 4);
for(int i = 0; i < width;i++) {
for(int j = 0;j<height;j++) {
int pixel = pixels_raw[i*width + j];
pixels.put((byte)((pixel >> 16) & 0xFF));
pixels.put((byte)((pixel >> 8) & 0xFF));
pixels.put((byte)(pixel & 0xFF));
pixels.put((byte)((pixel >> 24) & 0xFF));
}
}
pixels.flip();
id = glGenTextures();
glBindTexture(GL_TEXTURE_2D, id);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_RGBA, GL_BYTE, pixels);
}
catch(IOException e) {
e.printStackTrace();
}
return id;
}
With this code I get this weird texture:

The original png doesn't have any blue pixels... The wood texture is recognizable.
Never Mind. At this row glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_RGBA, GL_BYTE, pixels); It should be GL_UNSIGNED_BYTE. I also changed from java buffered image reader to stb image loading...
