带有TCPDF库的Datamatrix 16x48用于PHP

Question

我需要在我的pdf上打印数据矩阵代码。

文档要求的格式是16x48 datamatrix ECC 200。

示例代码是：18800000571920119916120010109364801000000128003896

结果必须是这一个：

我正在使用PHP的TCPDF库，这是我的代码：

$code = '18800000571920119916120010109364801000000128003896';
$style = array(
    'border' => true,
    'vpadding' => 'auto',
    'hpadding' => 'auto',
    'fgcolor' => array(0,0,0),
    'bgcolor' => false, //array(255,255,255)
    'module_width' => 1, // width of a single module in points
    'module_height' => 1, // height of a single module in points
    'position' => 'S'
);
$pdf->write2DBarcode($code, 'DATAMATRIX', 150, 10, 80, 50, $style, 'N', true);

在include / barcodes / datamatrix.php文件中，我评论了所有大小的数据矩阵，只留下了16x48（因为如果我全部留下，我的标准尺寸为32x32）。

这就是我得到的：

左侧部分与正确的结果非常相似，但右侧部分完全是白色!!!

我做错了什么？

Answer 1

Datamatrix构造函数检查要使用的最合适的表单大小。表单定义（正方形和矩形）在Datamatrix类（l.147到l.177）中定义。出于测试目的，我在正方形之前放置了矩形形式定义。如果给定的数据不是太长，它会生成一个16x48的数据矩阵，但我没有测试数据的完整性。 include / barcodes / datamatrix.php：
