[JAVA3D] BufferedImage, again...

[Corysia Taware]

  Well, I'm not any closer.  This is what I have now:

 

 

      TextureLoader textureLoader = new TextureLoader(filename, this);
      BufferedImage texBuff = textureLoader.getImage().getImage();

      Texture texture = textureLoader.getTexture();
      int width = texture.getWidth();
      int height = texture.getHeight();

 

      // this is the new image we're going to make
      BufferedImage buffer = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);

 

      for (int x = 0; x < width; x++)
        for (int y = 0; y < height; y++) {
          int rgb = texBuff.getRGB(x, y);
          int a = 128;                    // 50% alpha

          byte bytes[] = Convert.intToBytes(rgb);
          System.out.print("[" + bytes[0] + "," + bytes[1] + "," + bytes[2] + "," + bytes[3] + "] becomes ");

          int rgba = rgb + (a << 24);
          buffer.setRGB(x, y, rgba);

          bytes = Convert.intToBytes(buffer.getRGB(x, y));
          System.out.println("[" + bytes[0] + "," + bytes[1] + "," + bytes[2] + "," + bytes[3] + "].");
        }
      texture = new Texture2D(Texture2D.BASE_LEVEL, Texture2D.RGBA, width, height);
      texture.setImage(0, new ImageComponent2D(ImageComponent2D.FORMAT_RGBA, buffer));

 

My output looks like this:

 

[-1,0,0,0] becomes [127,0,0,0].
[-1,0,0,0] becomes [127,0,0,0].
[-1,0,0,0] becomes [127,0,0,0].

...etc...

 

  It sure looks to me like the alpha value is set, but my texture remains opaque.  I've verified that I am using this generated texture by changing 'rgba' to '0' and 'Integer.MAX_VALUE - 1' and got the results I expected (opaque black and white textures, respectively).
