/**
* 基本图片处理，用于完成图片缩入，水印添加
* 当水印图超过目标图片尺寸时，水印图能自动适应目标图片而缩小
* 水印图可以设置跟背景的合并度

使用方法:
自动裁切:
程序会按照图片的尺寸从中部裁切最大的正方形，并按目标尺寸进行缩略
$t->setSrcImg(“img/test.jpg”);
$t->setCutType(1);//这一句就OK了
$t->setDstImg(“tmp/new_test.jpg”);
$t->createImg(60,60);
手工裁切:
程序会按照指定的位置从源图上取图
$t->setSrcImg(“img/test.jpg”);
$t->setCutType(2);//指明为手工裁切
$t->setSrcCutPosition(100, 100);// 源图起点坐标
$t->setRectangleCut(300, 200);// 裁切尺寸
$t->setDstImg(“tmp/new_test.jpg”);
$t->createImg(300,200);
