PFA....
please find the below code for the same.
----------------------------------------------------------------------------------------
$im = @imagecreate(150,20);
$back = imagecolorallocatealpha($im,255,255,255,127);
$text = imagecolorallocate($im,233,14,91);
imagestring($im,20,40,2,$rand,$text);

$bimg = base64_encode(ob_get_contents());
imagedestroy($im);
ob_end_clean();
$attr['src'] = 'data:image/gif;base64,'.$bimg;
$img_captcha = html::img($attr);
$input_captcha = new html_inputfield(array('name' => '_captcha', 'id' => 'rcmlogincaptcha'));
$table->add('title', html::label('captcha', html::quote($this->app->gettext('captcha'))));
$table->add('captcha',$img_captcha);

Thanks in Advance!
I have sorted out the issue at my level using imagettftext function.
as below,
$font = '/usr/share/fonts/dejavu/DejaVuSerif-BoldItalic.ttf';
imagettftext($im,20,0,100,20,$text,$font,$random_text);
$text==color
$random_text==random alphanumeric value
$font== local font type
