What are common issues when using the GD library in PHP for image generation, especially when dealing with text and fonts?

Issue: One common issue when using the GD library in PHP for image generation, especially when dealing with text and fonts, is the text appearing blurry or distorted due to improper font settings. Solution: To ensure that the text appears crisp and clear, it is important to set the correct font path and size when using the GD library in PHP. 

// Set the font path and size
$font = 'path/to/font.ttf';
$fontSize = 12;

// Create a new image
$image = imagecreate(200, 50);

// Set the font color and background color
$fontColor = imagecolorallocate($image, 255, 255, 255);
$bgColor = imagecolorallocate($image, 0, 0, 0);

// Set the font settings
imagettftext($image, $fontSize, 0, 10, 30, $fontColor, $font, 'Hello World');

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

// Free up memory
imagedestroy($image);
