[fw-general] Zend_PDF right align text?

[ArticSun]

Hi all!

   At the moment I need to align text to the right (prices of an invoice all
need to align at the right). But how do I do this? I found the following
code:

function get_text_width($text_line,$current_font, $font_size)
{  
    $glyph_array = array();
    $total_item_width = 0;
    $text_array = str_split($text_line,1);
    foreach($text_array as $character)
    {
        $glyph_array[] = ord($character);
    }
    
   $oPage->drawText($oFont->getUnitsPerEm(), 10, 10);

    $text_width = $current_font->widthsForGlyphs($glyph_array);
    foreach($text_width as $char_width)
    {
        $total_item_width = $total_item_width + $char_width;
    }
    return ($total_item_width/1000)*$font_size;
} 

This seems to do SOMEthing, but if I take the right border at 1000 and I
take the result of the function of this, it still isn't aligned at the
right. It seems like the returned value isn't right.

Does anyone have a suggestion on how to correctly align text items to the
right?

Thanks!
