/* PHP Barcode Image Generator v1.0 [9/28/2000]
|
||||
Copyright (C)2000 by Charles J. Scheffold - cs@sid6581.net
|
||||
|
||||
UPDATE 15/11/2014 by J.Peelaerts
|
||||
Show text only if content is not empty
|
||||
---
|
||||
UPDATE 2/9/2013 by C.Scheffold
|
||||
Now compatible with POST requests when register_globals is off
|
||||
---
|
||||
UPDATE 5/10/2005 by C.Scheffold
|
||||
Changed FontHeight to -2 if no text is to be displayed (this eliminates
|
||||
the whitespace at the bottom of the image)
|
||||
---
|
||||
UPDATE 03/12/2005 by C.Scheffold
|
||||
Added '-' character to translation table
|
||||
---
|
||||
UPDATE 09/21/2002 by Laurent NAVARRO - ln@altidev.com - http://www.altidev.com
|
||||
Updated to be compatible with register_globals = off and on
|
||||
---
|
||||
UPDATE 4/6/2001 - Important Note! This script was written with the assumption
|
||||
that "register_globals = On" is defined in your PHP.INI file! It will not
|
||||
work as-is and as described unless this is set. My PHP came with this
|
||||
enabled by default, but apparently many people have turned it off. Either
|
||||
turn it on or modify the startup code to pull the CGI variables in the old
|
||||
fashioned way (from the HTTP* arrays). If you just want to use the functions
|
||||
and pass the variables yourself, well then go on with your bad self.
|
||||
---
|
||||
|
||||
This code is hereby released into the public domain.
|
||||
Use it, abuse it, just don't get caught using it for something stupid.
|
||||
|
||||
|
||||
The only barcode type currently supported is Code 3 of 9. Don't ask about
|
||||
adding support for others! This is a script I wrote for my own use. I do
|
||||
plan to add more types as time permits but currently I only require
|
||||
Code 3 of 9 for my purposes. Just about every scanner on the market today
|
||||
can read it.
|
||||
|
||||
|
||||
PARAMETERS:
|
||||
-----------
|
||||
$barcode = [required] The barcode you want to generate
|
||||
|
||||
|
||||
$type = (default=0) It's 0 for Code 3 of 9 (the only one supported)
|
||||
|
||||
$width = (default=160) Width of image in pixels. The image MUST be wide
|
||||
enough to handle the length of the given value. The default
|
||||
value will probably be able to display about 6 digits. If you
|
||||
get an error message, make it wider!
|
||||
|
||||
|
||||
$height = (default=80) Height of image in pixels
|
||||
|
||||
$format = (default=jpeg) Can be "jpeg", "png", or "gif"
|
||||
|
||||
$quality = (default=100) For JPEG only: ranges from 0-100
|
||||
|
||||
|
||||
$text = (default=1) 0 to disable text below barcode, >=1 to enable
|
||||
|
||||
|
||||
NOTE: You must have GD-1.8 or higher compiled into PHP
|
||||
in order to use PNG and JPEG. GIF images only work with
|
||||
GD-1.5 and lower. (http://www.boutell.com)
|
||||
|
||||
|
||||
ANOTHER NOTE: If you actually intend to print the barcodes
|
||||
and scan them with a scanner, I highly recommend choosing
|
||||
JPEG with a quality of 100. Most browsers can't seem to print
|
||||
a PNG without mangling it beyond recognition.
