* mode 1 : 强制裁剪，生成图片严格按照需要，不足放大，超过裁剪，图片始终铺满
* mode 2 : 和1类似，但不足的时候 不放大 会产生补白，可以用png消除。
* mode 3 : 只缩放，不裁剪，保留全部图片信息，会产生补白，
* mode 4 : 只缩放，不裁剪，保留全部图片信息，此时的参数只是限制了生成的图片的最大宽高，不产生补白
* mode 5 : 生成的图比例严格按照需要的比例，宽和高不超过给定的参数。
* 默认补白为白色，如果要使补白成透明像素，请使用SaveAlpha()方法代替SaveImage()方法
*
* 调用方法：
*
* $ic=new ImageCrop('old.jpg','afterCrop.jpg');
* $ic->Crop(120,80,2);
* $ic->SaveImage();
* //$ic->SaveAlpha();将补白变成透明像素保存
* $ic->destory();
*
