//We can get this information natively from the raster with this:

byte[] pixels = ((DataBufferByte) img. getRaster() . getDataBuffer() ) . getData() ;
for (int i = 0; i < pixels. length / 3 ; i++) {
int blue = Byte. toUnsignedInt(pixels[3*i] ) ;
int green = Byte. toUnsignedInt(pixels[3*i+1] ) ;
int red = Byte. toUnsignedInt(pixels[3*i+2] ) ;
