The overall purpose
of tweaking

is to read the modified data
as great,

to look and read until the
overall purpose

is image and error correction
and great.

Great. It looks exactly like
the same before

just with the error correction
tweaked.

Change it through the
decoder again

and it works great –
tweaking

your settings in the decoder
to look and read and

test out until the overall purpose
is error.
