$ this-> image_lib-> resize（）;返回false

Question

[如果文件大小大于1MB，我正在使用代码调整图像的大小，我在模型函数中使用了此功能，但是它返回false。这里有什么问题。

if($_FILES[$name]['size']/(1024)>1024){

    $upload_data = $this->upload->data();

    $config2['image_library'] = 'ImageMagick';  
    $config2['source_image'] = $upload_data["file_path"];  
    $config2['create_thumb'] = TRUE;  
    $config2['maintain_ratio'] = TRUE;  
    $config2['quality'] = '60%';  
    $config2['width'] = 200;  
    $config2['height'] = 200;  
    //$config2['new_image'] = $upload_data["file_name"];  

    $this->load->library('image_lib', $config2); 
    $this->image_lib->clear();
    $this->image_lib->initialize($config2);

    var_dump($this->image_lib->resize());

}

您不应在if中加载image_lib。尝试使用下面的代码

$this->load->library('image_lib');

if($_FILES[$name]['size']/(1024)>1024){

    $upload_data = $this->upload->data();

    $config2['image_library'] = 'ImageMagick';  
    $config2['source_image'] = $upload_data["file_path"];  
    $config2['create_thumb'] = TRUE;  
    $config2['maintain_ratio'] = TRUE;  
    $config2['quality'] = '60%';  
    $config2['width'] = 200;  
    $config2['height'] = 200;  
    //$config2['new_image'] = $upload_data["file_name"];  

    $this->image_lib->clear();
    $this->image_lib->initialize($config2);

    var_dump($this->image_lib->resize());

}
