名称

partition_rectanglepartition_rectanglePartitionRectanglePartitionRectanglepartition_rectangle — Partition a region into rectangles of approximately equal size.

参数签名

描述

partition_rectanglepartition_rectanglePartitionRectanglePartitionRectanglePartitionRectanglepartition_rectangle partitions the input region into rectangles having an extent of WidthWidthWidthWidthwidthwidth times HeightHeightHeightHeightheightheight. The rectangles are returned in PartitionedPartitionedPartitionedPartitionedpartitionedpartitioned. The region is always split into rectangles of approximately equal size. If this is not possible with the requested rectangle size, then WidthWidthWidthWidthwidthwidth and HeightHeightHeightHeightheightheight are adapted so that the size of the resulting rectangles is approximately equal. If the region is smaller than the given size, its output remains unchanged. A partition is only done if the size of the region is at least 1.5 times the size of the rectangle given by the parameters.

运行信息

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Automatically parallelized on tuple level.

结果

partition_rectanglepartition_rectanglePartitionRectanglePartitionRectanglePartitionRectanglepartition_rectangle 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>)set_system("no_object_result",<Result>), 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>)set_system("empty_region_result",<Result>), and the behavior in case of an empty result region via 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">). If necessary, an exception is raised.
