Binary Data Signing by GPG

I am trying to write a Java program that verifies the signature
generated using "gpg" for binary data. The same program for signed text
data works fine. For binary data I always get the error "invalid
signature", though the data and signature, keys seems to be correct.
Looks like some manipulations [like dash-escaping] were done to the
binary data by "gpg" before signing. 
Any information on what all exact manupulations that "gpg" does before
signing the binary data would be helpful.
