'imagettftext() function not working?

I input this code to show text convert into image.

<?php
// Set the content-type
header('Content-Type:image/png');

// Create the image
$im = imagecreatetruecolor(400, 30);

// Create some colors
$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);
 imagefilledrectangle($im, 0, 0, 399, 29, $white);

// The text to draw
$text = 'Testing...';
// Replace path by your own font path
$font="arial.ttf";

// Add some shadow to the text
imagettftext($im, 20, 0, 11, 21, $grey, $font, $text);

// Add the text
imagettftext($im, 20, 0, 10, 20, $black, $font, $text);

// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);
?>

And after this the OUTPUT is::

Output in mozilla

I'm using WAMP in windows and also GD installed... My gd_info() :

array (size=12)
'GD Version' => string 'bundled (2.1.0 compatible)' (length=26)
'FreeType Support' => boolean true
'FreeType Linkage' => string 'with freetype' (length=13)
'T1Lib Support' => boolean false
'GIF Read Support' => boolean true
'GIF Create Support' => boolean true
'JPEG Support' => boolean true
'PNG Support' => boolean true
'WBMP Support' => boolean true
'XPM Support' => boolean true
'XBM Support' => boolean true
'JIS-mapped Japanese Font Support' => boolean false

So finally what I have to do... Please help me......

Solution 1:[1]

you need to specify the full path to the font file.

and give 755 permission to the font file

class CaptchaSecurityImages {

    var $font = 'monofont.ttf';

    function getFontPath(){
        return $_SERVER['DOCUMENT_ROOT'].'/captcha/monofont.ttf';
    }

    function generateCode($characters) {
        /* list all possible characters, similar looking characters and vowels have been removed */
        $possible = '012345678';
        $code = '';
        $i = 0;
        while ($i < $characters) { 
            $code .= substr($possible, mt_rand(0, strlen($possible)-1), 1);
            $i++;
        }
        return $code;
    }

    function CaptchaSecurityImages($width='120',$height='40',$characters='6') {
        $code = $this->generateCode($characters);
        /* font size will be 75% of the image height */
        $font_size = $height * 0.75;
        $image = @imagecreate($width, $height) or die('Cannot initialize new GD image stream');
        /* set the colours */
        $background_color = imagecolorallocate($image, 255, 255, 255);
        $text_color = imagecolorallocate($image, 20, 40, 100);
        $noise_color = imagecolorallocate($image, 100, 120, 180);
        /* generate random dots in background */
        for( $i=0; $i<($width*$height)/3; $i++ ) {
            imagefilledellipse($image, mt_rand(0,$width), mt_rand(0,$height), 1, 1, $noise_color);
        }
        /* generate random lines in background */
        for( $i=0; $i<($width*$height)/150; $i++ ) {
            imageline($image, mt_rand(0,$width), mt_rand(0,$height), mt_rand(0,$width), mt_rand(0,$height), $noise_color);
        }
        /* create textbox and add text */
        $textbox = imagettfbbox($font_size, 0, $this->getFontPath(), $code) or die('Error in imagettfbbox function');
        $x = ($width - $textbox[4])/2;
        $y = ($height - $textbox[5])/2;
        imagettftext($image, $font_size, 0, $x, $y, $text_color, $this->getFontPath() , $code) or die('Error in imagettftext function');
        /* output captcha image to browser */
        header('Content-Type: image/jpeg');
        imagejpeg($image);
        imagedestroy($image);
        $_SESSION['security_code'] = $code;
    }

}

$width = isset($_GET['width']) ? $_GET['width'] : '120';
$height = isset($_GET['height']) ? $_GET['height'] : '40';
$characters = isset($_GET['characters']) && $_GET['characters'] > 1 ? $_GET['characters'] : '6';

$captcha = new CaptchaSecurityImages($width,$height,$characters);

Solution 2:[2]

If it worked after you comment to both call to imagettftext(), make sure file arial.ttf exists in same directory of script. Also comment out call to header() to be able to view any error message returned.
