使用imagettftext（）

Question

是否可以在一个font-size内的图片上设置不同的imagettftext()？

我已设法在图像上输出所需的文字。现在，我想在较大的$subheadliner_thu_1中显示font-size。我不想把它放在一个新的imagettftext()中，因为文本的长度将来可能会改变。因此，设置坐标不应用于$undercard_thu_4。

这是我的代码：

<?php
  header('Content-type: image/jpeg');
  $jpg_image = imagecreatefromjpeg('img/pkp-empty.jpg');
  $white = imagecolorallocate($jpg_image, 255, 255, 255);
  $font_path = 'fonts/calibri.ttf';

  $undercard_thu_1 = "amelie lens";
  $undercard_thu_1 = strtoupper($undercard_thu_1);
  $undercard_thu_2 = "beautifull swimmers";
  $undercard_thu_2 = strtoupper($undercard_thu_2);
  $undercard_thu_4 = "cypress hill";
  $undercard_thu_4 = strtoupper($undercard_thu_4);
  $subheadliner_thu_1 = "chance the rapper";
  $subheadliner_thu_1 = strtoupper($subheadliner_thu_1);

  $lineup_upper1 = $undercard_thu_1 . ' • ' . $undercard_thu_2;
  $lineup1 = wordwrap($lineup_upper1, 60, "\n", false);

  $lineup_upper2 = $subheadliner_thu_1 . ' • ' . $undercard_thu_4;
  $lineup2 = wordwrap($lineup_upper2, 60, "\n", false);

  imagettftext($jpg_image, 25, 0, 295, 532, $white, $font_path, $lineup1);
  imagettftext($jpg_image, 25, 0, 72, 579, $white, $font_path, $lineup2);

  imagejpeg($jpg_image);
  imagedestroy($jpg_image);
?>
