partition_dynamic — Partition a region horizontally at positions of small vertical extent.
partition_dynamic partitions the input Region horizontally into regions that have an approximate width of Distance. The input region is split at positions where it has a relativly small vertical extent.
The positions where the input region is split are determined by the following approach: First, initial split positions are determined such that they are equally distributed over the horizontal extent of the input region, i.e., such that all the resulting parts would have the same width. For this, the number n of resulting parts is determined by dividing the width of the input region by Distance and rounding the result to the closest integer value. The distance between the initial split positions is now calculated by dividing the width of the input region by n. Note that the distance between these initial split positions is typically not identical to Distance. Then, the final split positions are determined in the neighborhood of the initial split positions such that the input region is split at positions where it has the least vertical extent within this neighborhood. The maximum deviation of the final split position from the initial split position is Distance*Percent*0.01.
The resulting regions are returned in Partitioned. Note that the input region is only partitioned if its width is larger than 1.5 times Distance.

partition_dynamic 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>), the behavior in case of an empty input region via set_system('empty_region_result',<Result>), and the behavior in case of an empty result region via set_system('store_empty_region',<'true'/'false'>). If necessary, an exception is raised.
