在多行中使用imagettftext函数?有人做过吗? [英] Using the imagettftext function with multiple lines? Anyone done this before?

问题描述

我正在用php创建透明文本-> png图像，到目前为止效果很好.唯一的问题是，由于宽度固定，我希望具有文字自动换行功能.或者可以在文本中插入换行符.有人有做这个的exp吗?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

尝试一下

$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帮助，因为我认为它太晚了……

I hope it helps to others as i think its toooooo late for you...
