Function Documentation

barcode_encode()

barcode_encode	(		$code,
			$encoding
	)

Encodes $code with $encoding using genbarcode OR built-in encoder if you don't have genbarcode only EAN-13/ISBN or UPC is possible.

You can use the following encodings (when you have genbarcode): ANY choose best-fit (default) EAN 8 or 13 EAN-Code UPC 12-digit EAN ISBN isbn numbers (still EAN-13) 39 code 39 128 code 128 (a,b,c: autoselection) 128C code 128 (compact form for digits) 128B code 128, full printable ascii I25 interleaved 2 of 5 (only digits) 128RAW Raw code 128 (by Leonid A. Broukhis) CBR Codabar (by Leonid A. Broukhis) MSI MSI (by Leonid A. Broukhis) PLS Plessey (by Leonid A. Broukhis)

Parameters

string	$code	Code

barcode_encode_genbarcode()

barcode_encode_genbarcode	(		$code,
			$encoding
	)

Encode result of genbarcode command.

Parameters

barcode_gen_ean_bars()

barcode_gen_ean_bars

(

$ean

)

Generate EAN bars.

Parameters

string

$ean

EAN to encode

Returns

string Encoded EAN

Definition at line 199 of file barcode.lib.php.

barcode_gen_ean_sum()

barcode_gen_ean_sum

(

$ean

)

Calculate EAN sum.

Parameters

string

$ean

EAN to encode

barcode_outimage()

barcode_outimage	(		$text,
			$bars,
			$scale = 1,
			$mode = "png",
			$total_y = 0,
			$space = ''
	)

Output image onto standard output, or onto disk if global filebarcode is defined.

Parameters

string	$text	the text-line (<position>:<font-size>:<character> ...)
string	$bars	where to place the bars (<space-width><bar-width><space-width><bar-width>...)
int	$scale	scale factor ( 1 < scale < unlimited (scale 50 will produce 5400x300 pixels when using EAN-13!!!))
string	$mode	png,gif,jpg (default='png')
int	$total_y	the total height of the image ( default: scale * 60 )
array	$space	default: $space[top] = 2 * $scale; $space[bottom]= 2 * $scale; $space[left] = 2 * $scale; $space[right] = 2 * $scale;

Returns

string|null
