Are there any specific considerations to keep in mind when using imagettf function in PHP for text rendering?

When using the imagettf function in PHP for text rendering, it is important to ensure that the TrueType font file (.ttf) is accessible and correctly specified in the function call. Additionally, make sure to set the font size, color, and position parameters appropriately for the desired text output. Finally, remember to handle any potential errors that may arise during the text rendering process to ensure smooth execution. 

<?php
// Specify the TrueType font file
$fontFile = 'arial.ttf';

// Set the font size, color, and position
$fontSize = 20;
$fontColor = imagecolorallocate($image, 255, 255, 255); // white color
$textX = 100;
$textY = 100;

// Check if the font file exists
if (file_exists($fontFile)) {
    // Create the image and render the text
    $image = imagecreate(200, 200);
    imagestring($image, $fontSize, $textX, $textY, "Hello World", $fontColor);
    
    // Output the image
    header('Content-type: image/png');
    imagepng($image);
    
    // Free up memory
    imagedestroy($image);
} else {
    echo "Font file not found.";
}
?>
