For fun -- making .gif barcode:
For my colleaugue Marguerite, I thought I'd make a barcode that said
"Marguerite". This is the one-liner:
barcode -b 'Marguerite' | gs -q -DNOPAUSE -sDEVICE=ppmraw -r200x200 -sOutputFile='|pnmcrop|ppmtogif -interlace >barcode.gif' -
I put it here:
http://epirh1.epi.umn.edu/~mbmiller/download/barcode.gif
barcode -b 'Marguerite' produces postscript output which is sent to
ghostscript. Ghostscript uses the netpbm library to translate the
postscript from stdin to .gif output. The "200x200" determines the size
of the output image and "barcode.gif" is the name of the output file.
I had everything I needed on Red Hat except for GNU barcode which I
downloaded and installed in about two minutes (it is tiny and fast). I
think I will enjoy working with barcodes. It is easy and kinda fun.
Mike
