I found the problem... One of my co-workers, to read the original TIFF
file, used the same read method you used, but after that here used the
GridCoverageFactory to generate a copy in the first read, im not sure why.
This worked on all TIFF without the Alpha band but with Alpha it generates
the err
Hi Lorenzo,
how do you get that grid object at the top of your code?
This is the full example I'm using and it didn't raise any issue.
It's basically your code plus a reading part at the beginning and a writing
part at the end to check the result.
public static void main(String[] args) throws IOE
Hi Daniele, im currently using 23.1 but i also tried with 23.4 and i get
the same result, seems like the alpha band can't be handled because i tried
to remove it with GDAL and everything works fine.

Hi Lorenzo,
which GeoTools version are you using?
I have just quickly tried with GeoTools master your very same code also
adding a final piece of code doing a rewrite on disk:
writer = new GeoTiffWriter(new File("d:/download/writeback.tif"), null);
writer.write(grid, null);
writer.dispose();
and
Hi, i have a problem that i dont understand if GEOTOOLS handles (maybe with
some HINTS), basically i read a TIFF image then i serialized it :
*public static byte[] gridToBytes(GridCoverage2D grid) throws IOException
{ ByteArrayOutputStream baos = new ByteArrayOutputStream(); GeoTiffWriter
