Question

我正在使用imagejpg（）在浏览器上显示图像并将文本放在图像上。

之前我已经使用过这个功能了。现在我切换了域名主机，也许PHP版本不同，因为图像现在没有显示。

它在屏幕中间显示一个小方块，就像一个断开的链接，但图像肯定在那里。

有人可以帮忙吗？

header('Content-type: image/jpeg');

// Create Image From Existing File
$jpg_image = imagecreatefromjpeg('images1/new_image.jpg');

// Allocate A Color For The Text
$red = imagecolorallocate($jpg_image, 255, 0, 0);
$green = imagecolorallocate($jpg_image, 0, 255, 0);

// Set Path to Font File
$font_path = 'canadian.ttf';

$text1 = "hello";
$text2 = "there";
$text3 = "world";

//Floor 17
  imagettftext($jpg_image, 12, 0, 272, 17, $green, $font_path, $text1);
  imagettftext($jpg_image, 12, 0, 200, 38, $green, $font_path, $text2);
  imagettftext($jpg_image, 12, 0, 480, 17, $green, $font_path, $text3);

  // Send Image to Browser
  imagejpeg($jpg_image);

  // Clear Memory
  imagedestroy($jpg_image);

提前谢谢。

我只是想通了。答案如下

我向下移动了标题，它解决了问题。

// Create Image From Existing File
$jpg_image = imagecreatefromjpeg('images1/new_image.jpg');

// Allocate A Color For The Text
$red = imagecolorallocate($jpg_image, 255, 0, 0);
$green = imagecolorallocate($jpg_image, 0, 255, 0);

// Set Path to Font File
$font_path = 'canadian.ttf';

$text1 = "hello";
$text2 = "there";
$text3 = "world";

//Floor 17
  imagettftext($jpg_image, 12, 0, 272, 17, $green, $font_path, $text1);
  imagettftext($jpg_image, 12, 0, 200, 38, $green, $font_path, $text2);
  imagettftext($jpg_image, 12, 0, 480, 17, $green, $font_path, $text3);

  header('Content-type: image/jpeg');

  // Send Image to Browser
  imagejpeg($jpg_image);

  // Clear Memory
  imagedestroy($jpg_image);

我遇到了同样的问题，发现如果标题前有一个空格，则该图像将不起作用。我能够将图像保存在服务器上，但无法让浏览器显示它。删除每个空白对我来说都是成功的窍门。我认为这是您的脚本在开始时无法与标头一起使用的原因。

PHP imagejpeg不在浏览器上显示图像
