When adding a view and adding a pdf display the following error is displayed.

Making Progress:
In tcpdf.php Made the following changes.
require_once(__DIR__.'/tcpdf_autoconfig.php');
// TCPDF static font methods and data
require_once(__DIR__.'/include/tcpdf_font_data.php');
// TCPDF static font methods and data
require_once(__DIR__.'/include/tcpdf_fonts.php');
// TCPDF static color methods and data
require_once(__DIR__.'/include/tcpdf_colors.php');
// TCPDF static image methods and data
require_once(__DIR__.'/include/tcpdf_images.php');
// TCPDF static methods and data
require_once(__DIR__.'/include/tcpdf_static.php');

TO

require_once('tcpdf_autoconfig.php');
// TCPDF static font methods and data
require_once('include/tcpdf_font_data.php');
// TCPDF static font methods and data

More notes to follow: Still getting errors on the page but it loads.

Got rid of the remaining errors by making the following changes to the tcpdf_autoconfig.php file:
if (!defined('K_TCPDF_EXTERNAL_CONFIG') OR !K_TCPDF_EXTERNAL_CONFIG) {
// define a list of default config files in order of priority
$tcpdf_config_files = array(__DIR__.'/config/tcpdf_config.php', '/etc/php-tcpdf/tcpdf_config.php', '/etc/tcpdf/tcpdf_config.php', '/etc/tcpdf_config.php');
foreach ($tcpdf_config_files as $tcpdf_config) {
if (file_exists($tcpdf_config) AND is_readable($tcpdf_config)) {
require_once($tcpdf_config);
break;
}
}
}

if (!defined('K_PATH_MAIN')) {
define ('K_PATH_MAIN', __DIR__.'/');
}

TO

if (!defined('K_TCPDF_EXTERNAL_CONFIG') OR !K_TCPDF_EXTERNAL_CONFIG) {
// define a list of default config files in order of priority
$tcpdf_config_files = array('config/tcpdf_config.php', 'etc/php-tcpdf/tcpdf_config.php', 'etc/tcpdf/tcpdf_config.php', 'etc/tcpdf_config.php');
foreach ($tcpdf_config_files as $tcpdf_config) {
if (file_exists($tcpdf_config) AND is_readable($tcpdf_config)) {
require_once($tcpdf_config);
break;
}
}
}

if (!defined('K_PATH_MAIN')) {
define ('K_PATH_MAIN', '');
}

Since this is a third party library I'm not entirely sure what the protocol is for patching this and fixing it.
