pdflib 9 PDF_add_textflow 不分隔前两行
pdflib 9 PDF_add_textflow doesn't separate first 2 lines
关于 PDFLib 的另一个问题。
当我尝试从以下 class 调用 setupMultilineTextflow() 函数时，前两行文本没有分开
// Abstract PDF class, holding generalised functions and
// intialising a new PDF file

函数调用发生在以下 class 中，其中值作为值数组提供：
"Datum:",
"Auftrags-NR:",
"Auftragsname:",
"Kunden-Nr:"
require 'AbstractPDF.php';
class Lieferschein extends AbstractPDF{
public function __construct(){
parent::__construct();
}
public function generateContent(){
//set up general order set fields
$orderDetailNames = array("Datum:", "Auftrags-NR:", "Auftragsname:", "Kunden-Nr:");
$fontName = "ZEISSFrutigerNextW1G-Light";
parent::setupMultilineTextflow(111, 350, 191, 520,
$fontName, "unicode", 9, $orderDetailNames);
parent:: endDocument();
return "";
}
}
调用结果在pdf中如下所示

我已经为此苦苦挣扎了一段时间，但无论我如何更改代码，它仍然以两个顶行结尾:-(
再次感谢。
I've been struggling with this for a while now, but no matter how I
change the code it still ends up with two top line together :-(
我从你的代码中看不出你在文本段之间添加了某种换行符。因此，当一行中的 space 足以容纳多个块时，您将在一行中获得文本。
如果你想有一个换行符，那么添加一个换行符（例如通过在 $line 添加 \n）。
请注意：不必以 create_textflow() 开头。当您应用为文本流句柄“0”（PHP，否则为 -1）时，您还可以使用 add_textflow() 创建新的文本流句柄。
