How to output a barcode to the monitor.
 

Hello,
I need to create a barcode and show it in my monitor.
I'm able generate qrencode and show it in my monitor but how about barcode.
I used this command
barcode -o /tmp/scanString.png -i /tmp/scanString.txt
where -o is the output file and -i is the input file that I have the text that needs to be converted. Let say the string inside the file is "hello".
After this command, I tried to do this, but it's not showing up anything in the monitor
/usr/bin/qiv --fullscreen --no_statusbar -c 32 -o white /tmp/scanString.png &
Please help.

Did you read the manual?
http://linux.die.net/man/1/barcode
barcode [-b - | string] [-e encoding] [-o - | outfile] [ other-flags ]

Google turned up these.
