ico 生成
use Zodream\Image\Ico;
$image = new Ico('1.png');
$image->saveAsSize('1.ico', $image->getSizes());
, (*10)
验证码
use Zodream\Image\Captcha;
$captcha = new Captcha();
$captcha->setConfigs([
'width' => 200,
'fontSize' => 20,
'fontFamily' => 'Ubuntu_regular.ttf'
]);
$source = $captcha->generate();
$captcha->verify($_POST['captcha'], $source);
默认配置, (*11)
[
'characters' => 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789', //随机因子
'length' => 4, //验证码长度
'fontSize' => 0, //指定字体大小
'fontColor' => '', //指定字体颜色, 可以是数组
'fontFamily' => null, //指定的字体
'width' => 100, // 图片宽
'height' => 30, // 图片高
'angle' => 0, //角度
'sensitive' => true, // 大小写敏感
'mode' => 0 // 验证码模式： 0 文字 1 公式
]

二维码
use Zodream\Image\QrCode;
$qr = new QrCode();
$image = $qr->encode('123123');
$image->save();
, (*13)
水印
文字水印, (*14)
$image = new WaterMark();
$image->instance()->loadResource('1.jpg');
$image->addTextByDirection('water');
自定义水印, (*15)
$image = new WaterMark();
$image->instance()->loadResource($file);
$font = new Font((string)app_path(config('disk.font')), 12, '#fff');
$textBox = $image->instance()->fontSize($text, $font);
// 根据文字的尺寸获取水印的位置
list($x, $y) = $image->getPointByDirection(WaterMark::RightTop, $textBox->getWidth(), $textBox->getHeight(), 20);
// 给文字添加阴影
$image->addText($text, $x + 2, $y + 2, $font->getSize(), '#777', $font->getFile());
$image->addText($text, $x, $y, $font->getSize(), $font->getColor(), $font->getFile());
, (*16)
滑动验证码
use Zodream\Image\SlideCaptcha;
$captcha = new SlideCaptcha();
$captcha->setConfigs([
'width' => 300,
'height' => 130,
]);
$captcha->instance()->open('bg.jpg');
$captcha->setShape('shape.jpg'); // 根据图片抠图
$source = $captcha->generate();
$captcha->verify($_POST['captcha'], $source);
$imgData = $captcha->toArray();
$html = '';
foreach ($imgData['imageItems'] as $point) {
$html .= sprintf('
', $point['x'], $point['y']);
}
$html = <<<HTML
<style>
.slide-box {
width: {$imgData['width']}px;
height: {$imgData['height']}px;
position: relative;
}
.slide-box .slide-img {
float: left;
margin: 0;
padding: 0;
background-image: url({$imgData['image']});
background-repeat: no-repeat;
width: {$imgData['imageItems'][0]['width']}px;
height: {$imgData['imageItems'][0]['height']}px;
}
.slide-box .slide-cut {
position: absolute;
top: {$imgData['controlY']}px;
background-image: url({$imgData['control']});
background-repeat: no-repeat;
width: {$imgData['controlWidth']}px;
height: {$imgData['controlHeight']}px;
z-index: 9;
}
</style>
HTML;

点击验证码
依次点击图片上的文字, (*18)
$captcha = new HintCaptcha();
$items = ['我', '就', '你', '哈'];
$captcha->setConfigs([
'width' => 300,
'height' => 130,
'fontSize' => 20,
'fontFamily' => 'Yahei.ttf', // 暂不支持字体图标 iconfont
'words' => $items,
'count' => 3,
]);
$captcha->instance()->open('images/banner.jpg');
$source = $captcha->generate();
$captcha->verify($_POST['captcha'], $source);
$imgData = $captcha->toArray();
