如何更改Php Gd中的字體和字體大小？

Question

我將更改5到50 100保存但結果不會更改任何內容每次只顯示小文本以及如何更改字體也$string = $user['name'];這行打印全名我們只需要fb圖形api的名字幫忙。

我的如下代碼：

$barcode1 = imagecreatefrompng($image_bg); 
      imagecopy($fullimage, $im1, 35, 74, 0, 0, 365, 317); 
      imagecopyresampled($fullimage, $barcode1, 0, 0, 0, 0, imagesx($fullimage), imagesy($fullimage), imagesx($barcode1), imagesy($barcode1)); 

$color = imagecolorallocate($fullimage, 0, 0, 0); 
$string = $user['name']; 
$fontSize = 5; 
$x = 95; 
$y = 344; 
$font = 'arial.ttf'; 

imagestring($fullimage, $fontSize, $x, $y, $string, $color); 

$imagename = date("Ymd") . uniqid() . uniqid() . uniqid() . '.jpg'; 
imagejpeg($fullimage, 'Apps/If_You_Produce/123321/' . $imagename, 100); 

$values['user_id'] = $userid; 
$values['image_name'] = $imagename; 
$db->insert($db_table_name, $values); 

Answer 1

不能使用10,50,100 - http://php.net/manual/en/function.imagestring.php

只有1-5（默認）

UPDATE

爲了能夠充分控制您可能想要使用的字體大小http://php.net/manual/en/function.imagettftext.php

例（從同一網站）：

<?php 
// Set the content-type 
header('Content-Type: image/png'); 

// Create the image 
$im = imagecreatetruecolor(400, 30); 

// Create some colors 
$white = imagecolorallocate($im, 255, 255, 255); 
$grey = imagecolorallocate($im, 128, 128, 128); 
$black = imagecolorallocate($im, 0, 0, 0); 
imagefilledrectangle($im, 0, 0, 399, 29, $white); 

// The text to draw 
$text = 'Testing...'; 
// Replace path by your own font path 
$font = 'arial.ttf'; 

// Add some shadow to the text 
imagettftext($im, 20, 0, 11, 21, $grey, $font, $text); 

// Add the text 
imagettftext($im, 20, 0, 10, 20, $black, $font, $text); 

// Using imagepng() results in clearer text compared with imagejpeg() 
imagepng($im); 
imagedestroy($im); 
?>
