Well i am using this php code to make a facebook application.I uploaded the font Arial.ttfto the root directory of my website. But still i am showing the error- Warning: imagettftext() [function.imagettftext]: Could not find/open font in /home/a2424901/public_html/index.php on line 35. I tried changing the case,but i did'nt worked for me. Where i went wrong in this code ?

回答1:

From the docs

Depending on which version of the GD library PHP is using, when fontfile does not begin with a leading / then .ttf will be appended to the filename and the library will attempt to search for that filename along a library-defined font path.

This seems to imply that the fontfile should be an absolute path, and if it isn't, the function will append another .ttf onto the end of it.

Specify the full path to the font file.

$font = "/home/a2424901/public_html/Arial.ttf";

Or omit the .ttf and use the GDFONTPATH. The documentation recommends the following:

In many cases where a font resides in the same directory as the script using it the following trick will alleviate any include problems.

putenv('GDFONTPATH=' . realpath('.'));
$font = "Arial";

回答2:

To add on to user2724960's answer; Changing the FontName to __DIR__ . '/graph/fonts/someFont.ttf' did it for me.

Full line:

$myPicture->setFontProperties(array("FontName"=>__DIR__ .  '/graph/fonts/someFont.ttf',"FontSize"=>14));

Don't forgot to replace "someFont" with the name of your font file (default: "Forgotte")

回答3:

if you are using pChart use this:

$myPicture->setFontProperties(array("FontName"=>"../fonts/Forgotte.ttf","FontSize"=>11));

回答4:

I had same problem. My font name was

Titr.TTF

and i changed it to

Titr.ttf

and its worked perfectly.

回答5:

My solve (works for me):

realpath('here/is/right/path/to/font.ttf');

回答6:

Please check for the font folder under Resources.
