PDF_fit_textline — Platziert einzelne Textzeile
Platziert eine einzelne Textzeile unter Berücksichtigung verschiedener Optionen am Referenzpunkt (x, y). Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben.
One point about using the PDF_show_boxed function.
It does not support Unicode. So if you need that support you will need to use this function or the text flow functions.
For right now, if you are using PDFlib Lite, you can still use the legacy (depreciated) PDF_show_boxed or $p->show_boxed functions to create a text area. This seems to be a good (if not as full-featured) alternative to the textflow functions, and definitely a whole lot easier than trying to write your own text wrapping/hyphenation solution.
A patch to the code below to handle an array bounds error that arises:
<?php
$nextText = "";
if ( ( count( $tmpTxt ) - 1 ) >= ( $i + 1 ) )
{ $nextText = $tmpTxt[ $i+1 ]; }
if ( ( strlen( $str ) + strlen( $nextText ) ) > $cols )
?>
Here is a function I created in order to allow me to do textblocks on pdflib lite. Hope this helps someone else, cause all the stuff I've found on php.net has helped me.
$p is your pdf resource
$text is the string to put in the box
$cols is the number col characters before a carriage return
$xcrd,$ycrd is lower left of first line.
This will accept \n as a newline/carriage return and use it to skip to next line. It is not setup to hyphenate words, but someday I'll build one, or buy the full pdf package. ;)
function text_block($p,$text,$cols,$xcrd,$ycrd)
{
$font_size=12; //font size, used to space lines on y axis
$tmplines = explode("\n",$text);
for($j=0;$j<count($tmplines);$j++)
{
$tmptxt = explode(" ",$tmplines[$j]);
$str="";
for($i=0;$i<count($tmptxt);$i++)
{
if($str=="") $str=sprintf("%s",$tmptxt[$i]);
else $str=sprintf("%s %s",$str,$tmptxt[$i]);
if((strlen($str) + strlen($tmptxt[$i+1])) > $cols)
{
pdf_fit_textline($p,$str,$xcrd,$ycrd,"");
$str="";
$ycrd-=$font_size;
}
}
pdf_fit_textline($p,$str,$xcrd,$ycrd,"");
$ycrd-=$font_size;
}
return $ycrd;
}
