简单使用教程

ico 生成

use Zodream\Image\Ico;

$image = new Ico('1.png');
$image->saveAsSize('1.ico', $image->getSizes());

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

[
    '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();

水印

文字水印

$image = new WaterMark();
$image->instance()->loadResource('1.jpg');
$image->addTextByDirection('water');

自定义水印

$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());

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('<div class="slide-img" style="background-position: %spx %spx"></div>', $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>
<div class="slide-box">
    <div class="slide-cut"></div>
    <div class="slide-list">
        {$html}
    </div>
    
</div>
HTML;

点击验证码

依次点击图片上的文字

$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();
