Save image from Sigma0_HH_db band with snappy

I need to save image from Sigma0_HH_db band.
When I work with a calibrated Sentinel-1 image I can use the readPixels() function to the Sigma0_HH_db band. Then I’m trying to save the values to a numpy array, but then it need to be normalized somehow so that the image remains correct.
I think there should be a snappy function to save the image as it is displayed with SNAP, but I can’t find it…
Please help me solve this problem!

Yes you can save images with snappy. There are already some threads in this forum available regarding image export. They are probably helpful for you.
