/**
* 在保持图像长宽比的情况下将图像裁减到指定大小
*
* crop() 在缩放图像时，可以保持图像的长宽比，从而保证图像不会拉高或压扁。
*
* crop() 默认情况下会按照 $width 和 $height 参数计算出最大缩放比例，
* 保持裁减后的图像能够最大程度的充满图片。
*
* 例如源图的大小是 800 x 600，而指定的 $width 和 $height 是 200 和 100。
* 那么源图会被首先缩小为 200 x 150 尺寸，然后裁减掉多余的 50 像素高度。
*
* 用法：
* @code php
* $image->crop($width, $height);
* @endcode
*
* 如果希望最终生成图片始终包含完整图像内容，那么应该指定 $options 参数。
* 该参数可用值有：
*
* - fullimage: 是否保持完整图像
* - pos: 缩放时的对齐方式
* - bgcolor: 缩放时多余部分的背景色
* - enlarge: 是否允许放大
* - reduce: 是否允许缩小
*
* 其中 $options['pos'] 参数的可用值有：
*
* - left: 左对齐
* - right: 右对齐
* - center: 中心对齐
* - top: 顶部对齐
* - bottom: 底部对齐
* - top-left, left-top: 左上角对齐
* - top-right, right-top: 右上角对齐
* - bottom-left, left-bottom: 左下角对齐
* - bottom-right, right-bottom: 右下角对齐
*
* 如果指定了无效的 $pos 参数，则等同于指定 center。
*
* $options 中的每一个选项都可以单独指定，例如在允许裁减的情况下将图像放到新图片的右下角。
*
* @code php
* $image->crop($width, $height, array('pos' => 'right-bottom'));
* @endcode
*
* @param int $width 新的宽度
* @param int $height 新的高度
* @param array $options 裁减选项
*
* @return Helper_ImageGD 返回 Helper_ImageGD 对象本身，实现连贯接口
