public static LCMSImageLayout createImageLayout(Raster r) {
LCMSImageLayout l = new LCMSImageLayout();
if (r instanceof ByteComponentRaster &&
r.getSampleModel() instanceof ComponentSampleModel) {
ByteComponentRaster br = (ByteComponentRaster)r;
ComponentSampleModel csm = (ComponentSampleModel)r.getSampleModel();
l.pixelType = CHANNELS_SH(br.getNumBands()) | BYTES_SH(1);
int[] bandOffsets = csm.getBandOffsets();
BandOrder order = BandOrder.getBandOrder(bandOffsets);
int firstBand = 0;
switch (order) {
case INVERTED:
l.pixelType |= DOSWAP;

break;
case DIRECT:
