        return false;

    // Check transfer type
    if (sm.getDataType() != DataBuffer.TYPE_INT)
        return false;

    SinglePixelPackedSampleModel sppsm;
    sppsm = (SinglePixelPackedSampleModel) sm;

    int[] masks = sppsm.getBitMasks();
    if (masks.length == 3) {
        if (requireAlpha)
            return false;
