签名
Herror crop_domain_rel(const Hobject Image, Hobject* ImagePart, const Hlong Top, const Hlong Left, const Hlong Bottom, const Hlong Right)
Herror T_crop_domain_rel(const Hobject Image, Hobject* ImagePart, const Htuple Top, const Htuple Left, const Htuple Bottom, const Htuple Right)
描述
crop_domain_relcrop_domain_relCropDomainRelCropDomainRelCropDomainRelcrop_domain_rel cuts a rectangular area from the input
images. The area is determined by the surrounding rectangle of the
domain of the input image. The rectangle can be influenced by the
control parameters to modify at the top (TopTopTopToptoptop), at the left
(LeftLeftLeftLeftleftleft), at the bottom (BottomBottomBottomBottombottombottom), and at the right
(RightRightRightRightrightright). Positive values results in a smaller, negative
values in a larger size. If all parameters are set to zero, the
region remains unchanged.
执行信息
- 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。
- 在通道级别上自动并行化。

结果
crop_domain_relcrop_domain_relCropDomainRelCropDomainRelCropDomainRelcrop_domain_rel 在所有参数正确时返回 2 ( H_MSG_TRUE )。当输入为空（未指定区域）时则可设置行为通过 set_system('no_object_result',<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>) 以及输入区域为空时可设置行为通过 set_system('empty_region_result',<Result>)set_system("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)SetSystem("empty_region_result",<Result>)set_system("empty_region_result",<Result>)。如有必要，则抛出异常。
