描述
dilation_rectangle1 dilation_rectangle1 DilationRectangle1 DilationRectangle1 DilationRectangle1 dilation_rectangle1 applies a dilation with a rectangular
structuring element to the input regions Region Region Region Region region region . The size
of the structuring rectangle is Width Width Width Width width width x
Height Height Height Height height height . The operator results in enlarged regions, and the
holes smaller than the rectangular mask in the interior of the
regions are closed.
dilation_rectangle1 dilation_rectangle1 DilationRectangle1 DilationRectangle1 DilationRectangle1 dilation_rectangle1 is a very fast operation because the
height of the rectangle enters only logarithmically into the runtime
complexity, while the width does not enter at all. This leads to
excellent runtime efficiency, even in the case of very large
rectangles (edge length > 100).
注意
dilation_rectangle1 dilation_rectangle1 DilationRectangle1 DilationRectangle1 DilationRectangle1 dilation_rectangle1 is applied to each input region
separately. If gaps between different regions are to be closed,
union1 union1 Union1 Union1 Union1 union1 or union2 union2 Union2 Union2 Union2 union2 has to be called first.
To enlarge a region by the same amount in all directions,
Width Width Width Width width width and Height Height Height Height height height must be odd. If this is not the
case, the region is dilated by a larger amount at the right or at
the bottom, respectively, than at the left or at the top.

复杂度
Let F1 be the area of an input region and H be the height of the
rectangle. Then the runtime complexity for one region is:
结果
dilation_rectangle1 dilation_rectangle1 DilationRectangle1 DilationRectangle1 DilationRectangle1 dilation_rectangle1 在所有参数正确时返回 2 ( H_MSG_TRUE )。当输入区域为空或不存在时,其行为可通过以下方式设置:
无区域:
set_system('no_object_result',<RegionResult>) set_system("no_object_result",<RegionResult>) SetSystem("no_object_result",<RegionResult>) SetSystem("no_object_result",<RegionResult>) SetSystem("no_object_result",<RegionResult>) set_system("no_object_result",<RegionResult>)
空区域:
set_system('empty_region_result',<RegionResult>) set_system("empty_region_result",<RegionResult>) SetSystem("empty_region_result",<RegionResult>) SetSystem("empty_region_result",<RegionResult>) SetSystem("empty_region_result",<RegionResult>) set_system("empty_region_result",<RegionResult>)
否则,将抛出异常。
