I don't have a tutorial, but I can explain how you might do this. Assuming
your BLACK textures and WHITE textures are 64x64 pixels, and that you need
64 squares for the chessboard (8x8), you'd need to create a BufferedImage of
512x512. Or:
BufferedImage destImage = new BufferedImage(512, 512,
BufferedImage.TYPE_INT_RGB);
You then would need to then copy the data from your textures into the
BufferedImage. You can create a BufferedImage out of the TextureLoader with
this line:
BufferedImage srcImage = texureloader.getImage().getImage();
Actually copying the data from each srcImage can be done a variety of ways.
You might look into getting a WriteableRaster from destImage and using
setRect() to copy in each of your squares to the appropriate offset. If
that fails, you can always loop over one BufferedImage and use getRGB(x, y)
and setRGB(x, y) on the other image, setting each pixel. This will probably
be much slower than my first suggestion, but I haven't used setRect()
before.
Finally, you can construct the final texture from the new BufferedImage with
these two lines:
Texture texture = new Texture2D(Texture2D.BASE_LEVEL, Texture2D.RGB,
width, height);
texture.setImage(0, new ImageComponent2D(ImageComponent2D.FORMAT_RGB,
destImage));
