[SOLVED] How to configure GD

[ryy705]

Hello,

I call the imagettfbbox function like so: imagettfbbox($font_size, 0, 'monofont.ttf', $code) but its generating the following error: 'imagettfbbox() [function.imagettfbbox]: Could not find/open font'

 

monofont.ttf is in the same folder. And the code executes fine on the server. It just won't work on my computer. This leads me to believe that GD is not installed correctly on my computer.

I get the following info about GD by running phpinfo():

GD Support 	enabled
GD Version 	2.0 or higher
FreeType Support 	enabled
FreeType Linkage 	with freetype
FreeType Version 	2.3.5
T1Lib Support 	enabled
GIF Read Support 	enabled
GIF Create Support 	enabled
JPG Support 	enabled
PNG Support 	enabled
WBMP Support 	enabled

 

My php.ini file is too large to post here. But if someone tells me what part to post I will gladly do so.  Thanks in advance.

GD is enabled so it should work. Is the font name all lowercase or should it have a capital letter? Posting your code would also help.

Thanks for your reply.  Yes I verified the name and spelling.  Even tried it's absolute path.  As I mentioned in my previous post, the code works fine when uploaded to a server.  It just doesn't work on my computer.  I got the code from http://www.white-hat-web-design.co.uk/articles/php-captcha.php.

 

I will go ahead and post the portion of the code that generates the error:

	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, 'monofont.ttf', $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->font, $code) or die('Error in imagettftext function');
	/* output captcha image to browser */
	header('Content-Type: image/jpeg');
	imagejpeg($image);
	imagedestroy($image);
	$_SESSION['security_code'] = $code;
}

I also used file_get_contents() to sure that monofont.ttf is readable.

Anymore advice? Please.

Try './monofont.tff' instead.  I think it worked for me like that.

Of all the stupid .......... It worked.

[DarkWater]

Yeah, don't know why it does that. =/
