名称

get_region_indexget_region_indexGetRegionIndexGetRegionIndexget_region_index — Index of all regions containing a given pixel.

参数签名

get_region_index(区域 : : Row, Column : Index)

描述

该算子 get_region_indexget_region_indexGetRegionIndexGetRegionIndexGetRegionIndexget_region_index returns the index of all regions in 区域区域区域区域区域区域 (range of values: 1 to n) containing the test pixel (RowRowRowRowrowrow,ColumnColumnColumnColumncolumncolumn), i.e.: The returned indices can be used, e.g., in select_objselect_objSelectObjSelectObjSelectObjselect_obj to select the regions containing the test pixel.

注意

If the regions overlap more than one region might contain the pixel. In this case all these regions are returned. If no region contains the indicated pixel the empty tuple (= no region) is returned.

运行信息

多线程类型:可重入(与非独占操作符并行运行)。
多线程作用域:全局(可以从任何线程调用)。
未经并行化处理。

参数表

区域区域区域区域区域区域 (input_object) region-array → object

Regions to be examined.

RowRowRowRowrowrow (input_control) point.y → (integer)

Line index of the test pixel.

Default: 100

Value range: Row Row Row Row row row (lin)

ColumnColumnColumnColumncolumncolumn (input_control) point.x → (integer)

Column index of the test pixel.

Default: 100

Value range: Column Column Column Column column column (lin)

IndexIndexIndexIndexindexindex (output_control) integer(-array) → (integer)

Index of the regions containing the test pixel.

Complexity

If F is the area of the region and N is the number of regions the mean runtime complexity is O(ln(sqrt(F)) * N).

结果

该算子 get_region_indexget_region_indexGetRegionIndexGetRegionIndexGetRegionIndexget_region_index 返回值 2 ( H_MSG_TRUE) 如果参数都是正确的。 The behavior in case of empty input (no input regions available) is set via 该算子 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>). If necessary an exception is raised.
