/*
 * created on 2010-6-21

 * the class for control image
 *
 * made by s71ence
 *
 * @$img_path 图片路径
 * @$is_auto_reduce 图片是否自动按照大小等级压缩 1是
 * @$is_appoint 是否手动进行压缩或放大 1是
 * @$multiple 手动指定压缩/放大比例
 * @$is_water_str 是否加水印文字 1是
 * @$water_str 水印文字
 * @$is_watermark 是否加水印图片 1是
 * @$logo_path 水印图片路径
 * @$is_display 是否显示图片 1是
 * @$is_create 是否生成压缩后的图片 1是
 *
 * 注:
 * 1.生成新图时不可显示图片，即$isdisplay和$iscreate不可同时置为1
 * 2.当图片宽或高小于1000时，需手动设置压缩比例进行压缩
 * 3.不建议启用水印,若要启用，建议原图片大小最好在1000以内
 * 4.水印文字中不可含有中文
 * 5.新生成的图片在原目录文件中，支持n个层级
