帝国CMS缩略图函数改进（GD库改进）

帝国CMS(EmpireCMS)缩略图函数改进（GD库改进）
本文关键字词：缩略图，缩略图函数，帝国CMS(EmpireCMS)，帝国CMS(EmpireCMS)，帝国CMS(EmpireCMS)缩略图去黑边框
第一种方式 帝国默认：
sys_ResizeImg($r[titlepic],宽,高,0);//帝国默认的不裁剪缩放生成缩略图的方式
第二种方式 帝国默认：
sys_ResizeImg($r[titlepic],宽,高,1);//帝国默认的裁剪缩放生成缩略图的方式
第三种方式 去掉裁剪不够时的黑边并且从图片缩放后中间裁剪：
sys_ResizeImg($r[titlepic],宽,高,2);//新加去黑边裁剪生成缩略图的方式
第四种方式 只固定图片的宽，高度不限制（类似不规则瀑布流的图片形式），高填写为大于0的任意整数数字：
sys_ResizeImg($r[titlepic],宽,高,3);//新加去黑边生成类似瀑布流格式的方式
前台调用方式如下<?=sys_ResizeImg($r[titlepic],宽,高,3) ?>
