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);
