Usage

This sample shows the simplest usage of add_pdf_font():

/* This should be used in a one-time filter or action */
$font_data =  [
    'font_name'   => 'Brandon Grotesque',
    'regular'     => '/path/to/ttf/font/file/BrandonGrotesqueLight.ttf',
];

$results = GPDFAPI::add_pdf_font( $font_data );

if ( ! is_wp_error( $results ) ) {
   /* Successfully installed */
}

If you want to install the italic, bold and bold italic variants pass all the associative key options:

/* This should be used in a one-time filter or action */
$font_data =  [
    'font_name'   => 'Brandon Grotesque',
    'regular'     => '/path/to/ttf/font/file/BrandonGrotesqueLight.ttf',
    'italics'     => '/path/to/ttf/font/file/BrandonGrotesqueLight-i.ttf',
    'bold'        => '/path/to/ttf/font/file/BrandonGrotesque-b.ttf',
    'bolditalics' => '/path/to/ttf/font/file/BrandonGrotesqueLight-bi.ttf',
];

$results = GPDFAPI::add_pdf_font( $font_data );

if ( ! is_wp_error( $results ) ) {
   /* Successfully installed */
}
