Hi,

I need to be able to create textures from BufferedImages but I'm running into this problem where the RGB components are premultiplied by the alpha component. This is not the behaviour I desire. This is the code I'm using:


                TextureData td = AWTTextureIO.newTextureData(gl.getGLProfile(),bi, config.useMipMaps);

after this call when I check the byte array in the TextureData object, the RGB values have all been premultiplied.
