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);
