Laravel Intervention/image图片处理扩展包的安装、使用与可能遇到的坑详解

composer require intervention/image

// 将下面代码添加到 providers 数组中
'providers' => [
 // ...
 Intervention\Image\ImageServiceProvider::class,
 // ...
 ],


// 将下面代码添加到 aliases 数组中
'aliases' => [
 // ...
 'Image' => Intervention\Image\Facades\Image::class,
 // ...
 ],

// 引入 composer autoload
require 'vendor/autoload.php';

// 导入 Intervention Image Manager Class
use Intervention\Image\ImageManager;

// 通过指定 driver 来创建一个 image manager 实例
$manager = new ImageManager(array('driver' => 'imagick'));

// 最后创建 image 实例
$image = $manager->make('public/foo.jpg')->resize(300, 200);

// 引入 composer autoload
require 'vendor/autoload.php';

// 导入 Intervention Image Manager Class
use Intervention\Image\ImageManagerStatic as Image;

// 通过指定 driver 来创建一个 image manager 实例 (默认使用 gd)
Image::configure(array('driver' => 'imagick'));

// 最后创建 image 实例
$image = Image::make('public/foo.jpg')->resize(300, 200);

php artisan vendor:publish --provider="Intervention\Image\ImageServiceProviderLaravel5"

return array(
 'driver' => 'imagick'
);

// 修改指定图片的大小
$img = Image::make('images/avatar.jpg')->resize(200, 200);

// 插入水印, 水印位置在原图片的右下角, 距离下边距 10 像素, 距离右边距 15 像素
$img->insert('images/watermark.png', 'bottom-right', 15, 10);

// 将处理后的图片重新保存到其他路径
$img->save('images/new_avatar.jpg');

/* 上面的逻辑可以通过链式表达式搞定 */
$img = Image::make('images/avatar.jpg')->resize(200, 200)->insert('images/new_avatar.jpg', 'bottom-right', 15, 10);
