第一步在配置文件中设置图片的大小和路径
return array(
//'配置项'=>'配置值'
'img_save'=>[
'size' =>[
'app_gszc_Card'=>[
'compress'=>array(
'w'=> 720,
'h'=> 520
),
'page_size'=>array(
'w'=> 720,
'h'=> 520
),
], ],
'save_path'=>[
'app_gszc_Card' => array(
'origin' => './Uploads/gszc_card/origin/',
'page_size' => './Uploads/gszc_card/page_size/',
)
]
]
);
