使用多行的 imagettftext 函数? [英] Using the imagettftext function with multiple lines?

问题描述

我正在使用 php 创建透明文本 -> png 图像，到目前为止还不错.唯一的问题是我希望能够由于固定的宽度而使文本自动换行.或者能够在文本中插入断线.有没有人做过这个?这是我的代码...

I'm creating transparent text -> png images with php and so far so good. The only problem is that I want the ability to have the text word wrap due to a fixed width.. Or alternatively be able to insert breaklines into the text. Has anyone had any exp doing this? here is my code...

<?php

$font = 'arial.ttf';
$text = 'Cool Stuff! this is nice LALALALALA LALA HEEH EHEHE';
$fontSize = 20;

$bounds = imagettfbbox($fontSize, 0, $font, $text); 

$width = abs($bounds[4]-$bounds[6]); 
$height = abs($bounds[7]-$bounds[1]); 



$im = imagecreatetruecolor($width, $height);
imagealphablending($im, false);
imagesavealpha($im, true);


$trans = imagecolorallocatealpha($im, 255, 255, 255, 127);

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


imagecolortransparent($im, $black);
imagefilledrectangle($im, 0, 0, $width, $height, $trans);


// Add the text
imagettftext($im, $fontSize, 0, 0, $fontSize-1, $grey, $font, $text);


imagepng($im, "image.png");
imagedestroy($im);


?>

推荐答案

试试这个

$text = 'Cool Stuff! this is nice LALALALALA LALA HEEH EHEHE';
$text = wordwrap($_POST['title'], 15, "\n");

我希望它对其他人有所帮助，因为我认为对您来说太晚了...
