[解决办法]
不是说了非常清楚了,resizeimage("图片地址", "处理后的宽度", "处理后的高度", "是否裁剪", "圆角度数", "倾斜度"); 

$resizeimage = new resizeimage(“你上传图片的地址”,"处理后的宽度", "处理后的高度", "是否裁剪", "圆角度数", "倾斜度"); 

把具体参数赋进去就可以了


[解决办法]
关键看构造函数,直接给制定参数即可。
function resizeimage($img, $corner, $wid, $hei,$c, $corner_radius, $angle){}
[解决办法]
错误一大堆,没有调试的意义
