    $x = rand(0, $img_width/($length/2));
    $y = 0;
}

    $font_size = 20;
    $x = rand(0, $img_width/($length/1.5));
    $y = $font_size+2;
}

但没有任何反应，如何更改字体大小，请帮助。

推荐答案

您正在更改正确的参数，无论是核心文件还是应用程序/ helpers文件。

You are changing the correct parameter, whether in the core file or the application/helpers file.

仔细检查您使用的字体。一些字体有一个大小，就是它。默认字体文件（texb.ttf）只有一个大小（？我认为...）。

Double check the font that you are using. Some fonts have one size and that is it. The default font file (texb.ttf) has only one size (? I think...).

我使用以下配置：

//----- Captcha Implementation -----
$this->load->helper('captcha');

$captchaSetup = array(
    'img_path'   => './captcha/',
    'img_url'    => base_url()."captcha/",
    'font_path'  => './assets/fonts/E004007T.TTF',
    'img_width'  => 250,
    'img_height' => 50,
    'expiration' => 7200
);

$capData['cap'] = create_captcha($captchaSetup);

选择一个字体文件并将其放入fonts文件夹并尝试。

Pick a font file and place it in the fonts folder and try it out.
