GsOneDataBarExpandedStacked Barcode type class GS1 DataBar Expanded Stacked (ISO/IEC 24724)

Multi-row variation of GS1 DataBar Expanded of 2 to 11 rows, each 2 to 20 segments wide and 34 modules high, divided by separator patterns of three module rows. The encoding is identical to GS1 DataBar Expanded; the symbol characters are laid out over the rows in order, every row but the last one carrying the same even number of them.

The second row and the following even rows are mirrored when they hold a number of segments that is a multiple of four, so that they start with a bar. An incomplete last row with an odd number of finder patterns is moved one module to the right, because its guard patterns would otherwise be symmetric.

Methods

__construct()

File: Type.php line 66

public __construct(string $code[, int $width = -1 ][, int $height = -1 ][, string $color = 'black' ][, array<string|int, int|float|string> $params = [] ][, array{int, int, int, int} $padding = [0, 0, 0, 0] ]) : mixed

Parameters

• $code : string: Barcode content
• $width : int = -1: Barcode width in user units (excluding padding). A negative value indicates the multiplication factor for each column.
• $height : int = -1: Barcode height in user units (excluding padding). A negative value indicates the multiplication factor for each row.
• $color : string = ‘black’: Foreground color in Web notation (color name, or hexadecimal code, or CSS syntax) or PDF spot color name
• $params : array<string|int, int|float|string> = []: Array containing extra parameters for the specified barcode type
• $padding : array{int, int, int, int} = [0, 0, 0, 0]: Additional padding to add around the barcode (top, right, bottom, left) in user units. A negative value indicates the number of rows or columns.
