Question

我一直在寻找128格式条形码的字体，以便使用PDFlib放置在PDF中。我到处寻找，似乎无法找到一个适用于我的扫描仪。尝试扫描时似乎没有识别条形码。

Iv使用了code128.tff，ADVC128C.TFF和ADVC128B.ttf字体，虽然它们似乎输出条形码，但扫描仪似乎都没有识别它。有没有人对此有任何好运，或者你知道我在哪里可以找到更多的字体来试用。

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;

这实际上输出条形码但扫描仪无法读取

您是否将Start（104），Checksum（75）和Stop（106）代码输出到该页面？如果您使用Code 128B，则条形码应与以下HTML生成的条形码类似。
