imagettftext（）：找不到/打开字体错误消息 [英] imagettftext(): Could not find/open font error message

问题描述

我正在尝试读取表单中的验证码图片。

I'm trying to read a captcha image in a form.

以下是表单代码：

<form class="login" method="POST" action="">
    <p class="title">Are you human?</p>
    <div id="captchaimage">
        <img src="generate.php">
    </div>
    <input type="text" name="scr" size="6" placeholder="Write what you see here" autofocus/>
    <input class="submititon" type="submit" value="Submit" name="submit"></input>
</form>

这是 generate.php 文件：

<?php 
session_start();
//header('Content-type: image/jpeg');
$text = $_SESSION['scr'];
$font_size = 26;
$image_width = 100;
$image_height = 40;

$image = imagecreate($image_width, $image_height);
imagecolorallocate($image,255,255,255);
$text_color = imagecolorallocate($image,0,0,0);

for($x=1;$x<=30;$x++){
    $x1 = rand(1, 100);
    $y1 = rand(1, 100);
    $x2 = rand(1, 100);
    $y2 = rand(1, 100);

    imageline($image, $x1, $y1 ,$x2 ,$y2, $text_color);
}

imagettftext($image, $font_size, 0, 15, 30, $text_color, 'font.ttf', $text);
imagejpeg($image);
?>

如您所见，我已注释掉 header（）查看此页面返回什么错误。错误是这样的：

As you can see I have commented out the header() to see what error this page returns. And the error is this:

警告：imagettftext（）：无法在第25行找到/打开字体

第25行：

imagettftext($image, $font_size, 0, 15, 30, $text_color, 'font.ttf', $text);

我不知道为什么会发生此错误，因为 font.ttf 文件正确放置在同一目录中。

I don't know why this error happens because the font.ttf file is placed correctly in the same directory.

那么这里发生了什么事？！

So what is going on here guys ?!

推荐答案

基于

    $image = Image::canvas(750, 300, '#f3f3f3');
    $image->text($title, 375, 150, function($font) {
        $font->file(realpath('fonts/font-file.ttf'));
        $font->size(44);
        $font->color('#ffffff');
        $font->align('center');
        $font->valign('center');
    });

您只需要将字体文件添加到| public / fonts / font-file.ttf

You just need to add font file to | public/fonts/font-file.ttf
