This is the error coming when i am running a script like


require_once 'Text/CAPTCHA.php';
require_once 'Image/Text.php';

// Set CAPTCHA options (font must exist!)
$imageOptions = array(
'font_size' => 24,
'font_path' => './',
'font_file' => 'arial.TTF',
'text_color' => '#DDFF99',
'lines_color' => '#CCEEDD',
'background_color' => '#555555'
);

// Set CAPTCHA options
$options = array(
'width' => 200,
'height' => 80,
'output' => 'png',
'imageOptions' => $imageOptions
);

// Generate a new Text_CAPTCHA object, Image driver
$c = Text_CAPTCHA::factory('Image');
$retval = $c->init($options);
if (PEAR::isError($retval)) {
printf('Error initializing CAPTCHA: %s!',
$retval->getMessage());
exit;
}

// Get CAPTCHA secret passphrase
$_SESSION['phrase'] = $c->getPhrase();

// Get CAPTCHA image (as PNG)
$png = $c->getCAPTCHAAsPNG();
if (PEAR::isError($png)) {
echo 'Error generating CAPTCHA!';
echo $png->getMessage();
exit;
}
