php - 用于 PDFlib 的 php 128 条码字体

Question

我一直在寻找 128 格式条形码的字体，以使用 PDFlib 放置在 PDF 中。Iv 到处找，似乎找不到适合我的扫描仪的。尝试扫描时似乎无法识别条形码。

Iv 使用了 code128.tff、ADVC128C.TFF 和 ADVC128B.ttf 字体，虽然它们似乎在输出条形码，但似乎没有扫描仪识别它。有没有人对此有任何运气，或者你知道我在哪里可以找到更多字体来试用。

以下是我的代码。

$p = new PDFlib();

$p->set_option("errorpolicy=return");
$p->set_option("stringformat=utf8");

if ($p->begin_document($outfile, "") == 0)
throw new Exception("Error: " . $p->get_errmsg());

/* Start page */
$p->begin_page_ext(0, 0, "width=300 height=300");

$p->set_option("FontOutline={Code128bWin=/data/Code128bWin.ttf}");

$font = $p->load_font("Code128bWin", "unicode", "");
if ($font == 0)
throw new Exception("Error: " . $p->get_errmsg());

$p->setfont($font, 20);
$p->fit_textline("B546546546546", $x, $y-=20, "");


$p->set_option("FontOutline={Code128bWinLarge=/data/Code128bWinLarge.ttf}");
$font = $p->load_font("Code128bWinLarge", "unicode", "");
if ($font == 0)
throw new Exception("Error: " . $p->get_errmsg());

$p->setfont($font, 20);
$p->fit_textline("B546546546546", $x, $y-=60, "");

/* Finish page */
$p->end_page_ext("");

$p->end_document("");

$buf = $p->get_buffer();
$len = strlen($buf);

header("Content-type: application/pdf");
header("Content-Length: $len");
header("Content-Disposition: inline; filename=font_resource.pdf");
print $buf;

这实际上输出了条形码，但扫描仪无法读取

您是否将开始 (104)、校验和 (75) 和停止 (106) 代码输出到页面？如果您使用 Code 128B，您的条码应该看起来像由以下 HTML 生成的条码。
