Are there any potential pitfalls to be aware of when using ImageTTFText() to include custom TTF fonts in GDlib?

When using ImageTTFText() to include custom TTF fonts in GDlib, one potential pitfall to be aware of is ensuring that the font file path is correct and accessible by the script. If the font file path is incorrect or the font file is not readable, GDlib will not be able to render the text using the custom font. To solve this issue, make sure to provide the correct path to the TTF font file and ensure that the file has the necessary read permissions. Additionally, it is recommended to use absolute file paths to avoid any path resolution issues. 

$fontFile = '/path/to/custom/font.ttf';

// Check if the font file is readable
if (!is_readable($fontFile)) {
    die('Error: Font file is not readable.');
}

// Use absolute file path for the font file
imagettftext($image, $size, $angle, $x, $y, $color, $fontFile, $text);
