#查看是否加载成功
php -i | grep tclip
tclip
tclip support => enabled
tclip.face_config_path => no value => no value
Copy after login

安装命令行

#cd 进入源码中的soft文件夹内
chmod +x ./tclip.sh
./tclip.sh
Copy after login

使用方法说明

第一种:在php中使用格式:

tclip(文件原路径,裁剪后的图片保存路径,裁剪后的图片宽度,裁剪后的图片高度)

示例:

$source_file = "/tmp/a.jpg";
$dest_file = "/www/a_dest.jpg";
$width = 400;
$height = 200;
tclip($source_file, $dest_file, $width, $height);
Copy after login

第二种:命令行

参数说明:
-s 原图路径
-d 裁剪后的图片保存路径
-w 裁剪后的图片宽度
-h 裁剪后的图片高度
./tclip -s a.jpg -d a_dest.jpg -w 400 -h 200
Copy after login
