Description

crop_domain_relcrop_domain_relCropDomainRelCropDomainRelCropDomainRel 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 (TopTopTopToptop), at the left (LeftLeftLeftLeftleft), at the bottom (BottomBottomBottomBottombottom), and at the right (RightRightRightRightright). Positive values results in a smaller, negative values in a larger size. If all parameters are set to zero, the region remains unchanged.

Result

crop_domain_relcrop_domain_relCropDomainRelCropDomainRelCropDomainRel returns 2 (H_MSG_TRUE) if all parameters are correct. The behavior in case of empty input (no regions given) can be set via 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>) and the behavior in case of an empty input region via 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>). If necessary, an exception is raised.
