Ch 7 imagettftext function failing to find fonts

sgtwwilson · April 15th, 2009, 09:01 PM

I am new to all of this and I have been struggling to get the imagettftext() function to work as it is written in the chapter 7 code.

The putenv('GDFONTPATH=' . 'C:/Windows/Fonts') does not seem to facilitate the use of fonts in the Windows font folder...

This bit of code below is taken from the book:

PHP Code:


			
//change this path to match your fonts directory and the desired font
putenv('GDFONTPATH=' . 'C:/Windows/Fonts');
$font = 'arial';

(SNIP)

// add the caption if requested
if (isset($_GET['capt'])) {
    imagettftext($image, 12, 0, 20, 20, 0, $font, $_GET['capt']);
}

The only way I have gotten it to work is to set $font = 'arial.ttf' and place the arial.ttf file into my ...apache2.2/htdoc folder.

I would love to know why the putenv call is not working; any help would be appreciated.

Thanks

Yeah, I'm getting the same error.

Tried copying the font into my htdocs folder, but that didn't work either.

Anyone knows why this is? Tried switching the /'s with \'s, but didn't help.

Me too i cant even get the above workaround to work...

I can't get the Caption & Watermark to work on page 202 onwards?!

I have downloaded the original code...changed the paths to my htdocs. But this still doesn't work....everything else but this.

Help.

I replaced the two relevant lines of codes at the top of both check_image.php and image_effect.php with the following:

Code:

putenv("GDFONTPATH=" . "C:/Windows/Fonts/");
$font = getenv('GDFONTPATH') . 'arial.ttf';

This solved the problem, at least on Windows Vista.

HTH,

And BTW, don't put any debugging statements in the image_effect.php file, like echo $font, or anything else that causes output. Because this file is called as the src attribute of an image element, it can only generate an image, not text output. When I tried to use echo to see what my variables and arrays were holding, the check_image program tried to put that where it expected an image. The result was no image, and annoyingly, no output or even an error message in the php-error log.

I think using an image generating program as the src attribute is pretty cool. But if anyone knows a way to get error and debugging info out of it, I'd love to here it. There must be a way to use stderr or stdout to do this on Linux, but on Windows? Any ideas?

Regards,
Boz
