What are the key parameters to consider when using imagettftext() in PHP, such as size, angle, and font file?

When using the imagettftext() function in PHP, it is important to consider key parameters such as size, angle, and font file. The size parameter determines the font size in points, the angle parameter specifies the angle in degrees in which the text is to be rendered, and the font file parameter should point to a TrueType font file on the server. By setting these parameters correctly, you can customize the appearance of text in images generated using PHP. 

<?php
// Set the parameters for imagettftext function
$font_size = 20;
$angle = 0;
$font_file = 'arial.ttf';

// Create a new image
$image = imagecreate(200, 100);

// Set the text color
$text_color = imagecolorallocate($image, 255, 255, 255);

// Add text to the image using imagettftext function
imagettftext($image, $font_size, $angle, 50, 50, $text_color, $font_file, 'Hello World');

// Output the image
header('Content-type: image/png');
imagepng($image);

// Free up memory
imagedestroy($image);
?>
