Klas,
You should be able to read the bytes and convert them.
Something like this should work (written on the fly, there might be
mistakes):
Image i = ...
byte[] b = i.getRawData();
byte[] grayscale = new byte[b.length%3];
int k = 0;
for (int j = 0; j < b.length; j+=3) {
//Y = 0.3*R + 0.59*G + 0.11*B
grayscale[k] = (byte)(.3*b[j]+.56*b[j+1]+.11*b[j+2]);
}
Image grayscaleImage = Image.getInstance(i.getWidth(), i.getHeight(), 1, 8,
grayscale);
....
-R
