Creating barcodes with PHP

I recently had a project where I had to create Code 128 barcodes. I found that the PHP freefont support did not attempt to use high ascii character values. I had to create my own routines and even my own Truetype font for code 128b.

This is my test page. I kept on going and now I have simple code 3 of 9 (Numbers and Capital letters, no special chracters).

Since any barcode system of any value has a charge, I am not giving this away. You can buy the font and the PHP code that produces the checksums for $10.

Simple Code 3 of 9 (no checksum)

Working on EAN-13 for ISBN Numbers - ISBN numbers start with 978 and the price info usually has a leading 5

The ISBN (12 digits) Price (five digits)

UPC is next.
