    Here's a little function that creates a pdf_show_xy_right() function with exactly the same parameters as pdf_show_xy(), except that the third parameter now specifies the right-aligned edge position.

    function pdf_show_xy_right(&$pdf, $text, $right, $bottom) {
        $fontname = pdf_get_parameter($pdf, "fontname", 0);
        $font = pdf_findfont($pdf, $fontname, "host", 0);
        $size = pdf_get_value($pdf, "fontsize", 0);
        $width = pdf_stringwidth($pdf, $text, $font, $size);
        pdf_show_xy($pdf, $text, $right-$width, $bottom);
    }

    Set your font name and size separately, just as you would with pdf_show_xy(), and then call this function like so:

    pdf_show_xy_right($pdf, "Hello World", 50, 200);

    The third parameter is the right edge, fourth parameter is the baseline.  You do NOT have to pass in the font and size!

    No, that's just because in PDF the origin is at the lower left corner

    When using PDFLib version 4.0.3 under PHP 4.2.1 on Windows the Y-position is reversed, which means, the Y is the number of pixels that should be visible BELOW the texts baseline.

    Want to do right-to-left text with pdflib? Just pick the right margin, and send it as $x to this function.

    <?php
    function pdf_show_xy_backwards ($pdf, $text, $font, $size, $x, $y) {
            $currx = $x;
        for (    $i = strlen($text); $i > 0; $i--) {
                $char = substr((string)$text, $i-1, 1);
                $width = pdf_stringwidth($pdf, (string)$char, $font, $size);
                $currx = $currx - $width;
                pdf_show_xy($pdf, (string)$char, $currx, $y);
        }
    }
    ?>
