How can the font size or style be adjusted when using the ImageString function in PHP?

When using the ImageString function in PHP to write text on an image, the font size and style cannot be directly adjusted within the function itself. Instead, you can use the ImageTTFText function which allows you to specify the font size, style, and other parameters. This function requires a TrueType font file to be loaded and used for rendering text on the image. 

// Create a new image with specified width and height
$image = imagecreate(200, 100);

// Set the background color
$bg_color = imagecolorallocate($image, 255, 255, 255);

// Set the text color
$text_color = imagecolorallocate($image, 0, 0, 0);

// Load a TrueType font file
$font = 'arial.ttf';

// Write text on the image with specified font size, style, and other parameters
imagettftext($image, 20, 0, 10, 50, $text_color, $font, 'Hello World');

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

// Free up memory
imagedestroy($image);
