描述
算子 inner_rectangle1inner_rectangle1InnerRectangle1InnerRectangle1InnerRectangle1inner_rectangle1 determines the largest
axis-parallel rectangle that fits into a region. The rectangle is
described by the coordinates of the corner pixels (Row1Row1Row1Row1row1row_1,
Column1Column1Column1Column1column1column_1, Row2Row2Row2Row2row2row_2, Column2Column2Column2Column2column2column_2).
In the documentation of this chapter (Regions / Features), you can
find an image illustrating regions which vary in the width and height
of their inner rectangle.
If more than one region is passed in RegionsRegionsRegionsRegionsregionsregions the results
are stored in tuples, the index of a value in the tuple
corresponding to the index of the input region. For empty regions
all parameters have the value 0 if no other behavior was set (see
set_systemset_systemSetSystemSetSystemSetSystemset_system).
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。
- 在内部数据级别上自动并行化。

结果
算子 inner_rectangle1inner_rectangle1InnerRectangle1InnerRectangle1InnerRectangle1inner_rectangle1 在输入不为空时返回值 2 ( H_MSG_TRUE )。当输入为空（无可用输入区域）时，可设置行为通过算子 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>)。空区域（区域是空集）的情况下的可设置行为通过
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>)。如有必要，则抛出异常。
