You should read the comments in that issue.
Basically it explains, that making it Portrait is non-trivial.
Some of the comments *MAY* help you in a particular case.
The comments did not help me though.
There is an enhanced version in the Google Play Market:

It is not free, but should support scanning in Portrait mode.
