Lib_freetype

Usage of lib_freetype

Lib_freetype is used by ezrenderer/lib_gd.php to create a titling image for the videos. More specifically, it is the function imagettfbbox(...) that uses lib_freetype to prepare a well sized box for title. You have to enable lib_freetype for the GD module of php.

Verification for lib_freetype

You can verify that your PHP is ready for titling image creation by using the following command in a shell (on the server that runs EZrenderer):

php -r "print_r(gd_info());"

You should receive such output:

Array
(
    [GD Version] => 2.0
    [FreeType Support] => 1
    [FreeType Linkage] => with freetype
    [T1Lib Support] => 1
    [GIF Read Support] => 1
    [GIF Create Support] => 1
    [JPEG Support] => 1
    [PNG Support] => 1
    [WBMP Support] => 1
    [XPM Support] => 
    [XBM Support] => 
    [JIS-mapped Japanese Font Support] => 
)

'FreeType Support' set to 1 means that your server is ready for creating titling image. If FreeType Support is set to 0, you have to install lib_freetype and enable it for PHP.

If you receive the following output, you have to enable GD module for PHP

PHP Fatal error: Call to undefined function gd_info() in Command line code on line 1
