Barcodes in postscript

Could you point me a way in which I can render a barcode in PS without the help of any external plugin or class file ?

开发者_开发技巧Thanks

Try postscriptbarcode and barcodewriter.

You would draw rectangles spaced and sized accordingly for the barcode symbology you are going to use.

Here is a list of symbologies:

If you're implementing this from scratch, I would suggest 2 of 5 or Code 39, as they have the simplest structure.
