描述
crop_rectangle2crop_rectangle2CropRectangle2CropRectangle2CropRectangle2crop_rectangle2 从每张输入图像中裁剪一个或多个矩形区域。这些区域由矩形表示，矩形通过中心点（RowRowRowRowrowrow, ColumnColumnColumnColumncolumncolumn）、方向角 PhiPhiPhiPhiphiphi 以及半边长 Length1Length1Length1Length1length1length_1 和 Length2Length2Length2Length2length2length_2 来定义。PhiPhiPhiPhiphiphi 以弧度为单位，沿数学正方向给出，表示水平轴与第一条边（长度为 Length1Length1Length1Length1length1length_1）之间的夹角。矩形参数使用以像素为中心的、亚像素精度的坐标，详见 变换 / 二维变换。
参数 AlignToAxisAlignToAxisAlignToAxisAlignToAxisalignToAxisalign_to_axis 决定输出图像的对齐方式。可能的取值：
执行信息
- 支持 OpenCL 计算设备。
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 在元组级别上自动并行化。
