名称
move_regionmove_regionMoveRegionMoveRegionmove_region — 平移一个区域。
签名
描述
move_regionmove_regionMoveRegionMoveRegionMoveRegionmove_region translates the input regions by the vector given by
(RowRowRowRowrowrow, ColumnColumnColumnColumncolumncolumn). If necessary, the resulting
regions are clipped with the current image format.
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。
参数
RegionRegionRegionRegionregionregion (输入对象) region(-array) → objectHRegionHObjectHRegionHobject
Region(s) to be moved.

RowRowRowRowrowrow (输入控制) point.y → HTupleintHTupleHtuple (integer) (int / long) (Hlong) (Hlong)
Row coordinate of the vector by which the
region is to be moved.

复杂度
Let F be the area of the input region. Then the runtime
complexity is O(F).
结果
move_regionmove_regionMoveRegionMoveRegionMoveRegionmove_region 始终返回值 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>)，当输入区域为空时则设置行为通过 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>)，以及当结果区域为空时则设置行为通过 set_system('store_empty_region',<'true'/'false'>)set_system("store_empty_region",<"true"/"false">)SetSystem("store_empty_region",<"true"/"false">)SetSystem("store_empty_region",<"true"/"false">)SetSystem("store_empty_region",<"true"/"false">)set_system("store_empty_region",<"true"/"false">)。如有必要，则抛出异常。
