【原创】yii2官方imagine图片处理扩展支持水印、尺寸，略图，裁剪，旋转

最近写个yii2编辑器扩展用到了官方图片处理扩展，这里顺便说下。 首先安装：composer require --prefer-dist yiisoft/yii2-imagine prefer-dist参数本地保存缓存，重新添加缓存读取。 扩展目录添加2个新目录 vendor/imagine vendor/yiisoft/yii2-imagine 使用先引入： use yii\imagine\Image; $image='@webroot/test-image.jpg'; $quality=75; //图片水印 Image::watermark($image, '@webroot/watermark.png', [0, 0])->save($image, ['quality' => $quality]); //文字水印 Image::text($image, 'netpc.com.cn测试', '@vendor/netpc/yii2-ueditor/assets/fonts/Alibaba-PuHuiTi-Heavy.otf', [0,0], ['color' => '#000000', 'size' =>16])->save($image, ['quality' => $quality]); //修改尺寸 $image = Image::resize($image, 600, 0)->save($image, ['quality' => $quality]); //裁剪 Image::crop($image, 120 , 120, [0, 0])->save($image, ['quality' => $quality]); //略图 Image::thumbnail($image, 120, 120 ,\Imagine\Image\ManipulatorInterface::THUMBNAIL_INSET)->save($image, ['quality' => $quality]); //旋转 Image::frame($image, 5, '666', 0)->rotate(-8)->save($image, ['quality' => $quality]); 其它可以参考我的写的composer require netpc/yii2-ueditor扩展或查看官方源码 @see https://github.com/yiisoft/yii2-imagine
