|
|
- Barcode-Images using libgd (png, jpg,gif), |
| 5 |
|

| 6 |
|
|

|
|
|

|
|
PHP-Barcode encodes using |
| 9 |
|
|
- a built-in EAN-13/ISBN Encoder |
| 10 |
|
|
- genbarcode (by Folke Ashberg), a command line |
| 11 |
|
|
barcode-encoder which uses GNU-Barcode |
| 12 |
|
|
genbarcode can encode EAN-13, EAN-8, UPC, ISBN, 39, 128(a,b,c), |
| 13 |
|
|
I25, 128RAW, CBR, MSI, PLS |

INSTALLATION: |
| 22 |
|
|
|
| 23 |
|
|
WHAT YOU NEED TO BE ABLE TO USE PHP-BARCODE |
| 24 |
|
|
You need php>4 on your system. |
| 25 |
|
|
You need the gd2-extension to be able to render images. |
| 26 |
|
|
You need a TrueTypeFont if you want to see the CODE below the bars. |
| 27 |
|
|
You need genbarcode (from www.ashberg.de/bar) in you want to use |
| 28 |
|
|
another encoding than EAN-12/EAN-12/ISBN |
| 29 |
|
|
|
| 30 |
|
|
Copy the following files into your html/php-directory |
| 31 |
|
|
- php-barcode.php - main library |
| 32 |
|
|
- encode_bars.php - built-in encoders |
| 33 |
|
|
optional: |
| 34 |
|
|
- barcode.php - Sample-File |
| 35 |
|
|
- white.png - for HTML-Images |
| 36 |
|
|
- black.png - for HTML-Images |
| 37 |
|
|
|
| 38 |
|
|
FONT-Installation |
| 39 |
|
|
UNIX: |
| 40 |
|
|
A TrueTypeFont isn't included in this distribution! |
| 41 |
|
|
Copy one into the html/php-directory and change in php-barcode.php |
| 42 |
|
|
$font_loc (change the arialbd.tff to your font name). |
| 43 |
|
|
arialbd.ttf from Windows looks great. |
| 44 |
|
|
|
| 45 |
|
|
WINDOWS: |
| 46 |
|
|
If you use Windows the font should be located automatically. |
| 47 |
|
|
|
| 48 |
|
|
OPTIONAL - genbarcode: |
| 49 |
|
|
If you want to generate not only EAN-12/EAN-13/ISBN-Codes you have to install |
| 50 |
|
|
genbarcode, a small unix-commandline tool which uses GNU-Barcode. |
| 51 |
|
|
genbarcode is available http://www.ashberg.de/bar , read genbarcodes |
| 52 |
|
|
README for installation. |
| 53 |
|
|
If you have installed genbarcode not to /usr/bin set the $genbarcode_loc |
| 54 |
|
|
in php-barcode.php . |
| 55 |
|
|
|
| 56 |
|
|
TESTING |
| 57 |
|
|
If everything works fine you should see an image if you call |
| 58 |
|
|
http://localhost/path/barcode.php |
| 59 |
|
|
|
| 60 |
|
|
Or call http://localhost/path/barcode.php?code=<CODE>&encoding=<ENCODING>&mode=<png|jpg|gif|html|text>&size=<1,2,3,...> |
| 61 |
|
|
|
| 62 |
|
|
|
| 63 |
|
|
|
| 64 |
|
|
If you need more then the sample barcode.php can do, you need to build your own. |
