Yii 使用intervention/image拓展实现图像处理功能

InterventionImageImageManagerStatic::make($_FILES['file']['tmp_name'])- save('upload.jpg');//file为上传表单的name名
InterventionImageImageManagerStatic::make($_FILES['file']['tmp_name'])- resize(300, 200)- save('upload.jpg');//file为上传表单的name名,并将上传的图片压缩成300,200

if ($_FILES['file']) {
  $image = $_FILES['file']['tmp_name'];
  if (is_array($image)) {
    //多图上传
    foreach ($image as $key =  $item) {
      InterventionImageImageManagerStatic::make($item)- save($key.'upload.jpg');
    }
  } else {
    //单图上传
    InterventionImageImageManagerStatic::make($image)- save('upload.jpg');
  }
}

//水印
ImageManagerStatic::make('upload.jpg')- text('水印文字',20,30,function($font){
  //配置水印字体
  $font- file(Yii::getAlias('@webroot') . '/simsun.ttc');
  //配置水印大小
  $font- size(30);
  //配置水印颜色
  $font- color('#fff');
  //配置水印水平居左( left, right and center)
  $font- align('left');
  //配置水印垂直居下(top, bottom and middle)
  $font- valign('bottom');
  //配置水印旋转角度
  $font- angle(45);
})- save('uploadWater.jpg');

ImageManagerStatic::make('upload.jpg')- insert('water.jpg','bottom-left',10,10)- save('uploadWater.jpg');
