To rotate a barcode add appropriate PostScript commands to its ps-file.
Take a look at the following example.  It's the beginning of a barcode
that I generated with the following command and I added one line:

barcode -b 12345 -o barcode.ps




%!PS-Adobe-2.0
%%Creator: "barcode", libbarcode sample frontend
%%DocumentPaperSizes: A4
%%EndComments
%%EndProlog

%%Page: 1 1

100 0 translate 90 rotate                       % <=== add this line here
% Printing barcode for "12345", scaled  1.00, encoded using "code 128-B"
% The space/bar succession is represented by the following widths (space first):
% 02112141232212232112211322212312132122141212331112
...



Now the barcode shows 90 degree rotated counter clockwise.
Hope this helps.
