Larger Font size for Captcha

<< < (2/2)

shwekhaw:
Strangely there is nothing in error log. I run test script mentioned in php.net and browser said the image cannot be displayed because it contains  error. All ttf files are in same folder as captcha.php (libs folder). I got them from under Win 7 as well my raspberry pi running wheezy.

Then your server settings probably prevents PHP warnings from appearing in error logs.

And what makes you think that the script from root directory will find the font file without full path?  ::)

Try this:


--- Code: ---$font = dirname(__FILE__) . '/arial.ttf';
--- End code ---

Sever is reporting other php errors in log file so I am assuming error is not with php. I am using example 1 at http://php.net/manual/en/function.imagettftext.php. Full path does not work either. I think the problem is with font file. I am not familiar with installing font in linux system. Do I need to install font to the system like in Windows or just copying should work?

A TTF font is just a file. So copying should be enough.

At the same time, I don't think that this problem is somehow related to Mibew Messenger. It looks more like a problem with PHP and/or some of its libraries. Or a problem with the font. Or with the environment (for example, with some system limits and/or insufficient system resources). As a matter of fact, I can only stare into a crystal ball and make abstract guesses.

Thanks. For now imagecopyresampled does the job.
