- 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);
