[JAVA2D] ColorModel#getComponents( Object, int[], int )

[Andrew M. Sheridan]

To all,

For an arbitrary image in any color space of type ColorSpace.TYPE_RGB (actually, any arbitrary RGB image decoded by JAI's com.sun.codec decoders... if that matters), will ColorModel's getComponents( Object, int[], int ) method always return the alpha (if present) as the last component?  If not, how does one determine which color/alpha component is alpha?

Some background: I am performing a linear color conversion ( ( red + green + blue ) / 3 ) and cannot use ColorModel's getRed, getGreen, and getBlue methods b/c they scale to 8bit.

Thanks in advance.
