Halcon算子翻译——break

名称

break - 结束循环执行或离开一个switch段。

用法

break( : : : )

描述

　　break结束最近的for，while，或repeat..until循环。 另外，break语句用于离开switch段，特别是在一个case分支的结尾处。 程序跳出，继续在随后的程序行中执行（The program execution is continued at the program line following the corresponding block.）。

　　不在循环或switch段的break语句无效。

案例(HDevelop)

read_image (Image, 'monkey')
threshold (Image, Region, 160, 180)
connection (Region, Regions)
Number := |Regions|
AllRegionsValid := 1
* check if for all regions area <=30
for i := 1 to Number by 1
  ObjectSelected := Regions[i]
  area_center (ObjectSelected, Area, Row, Column)
  if (Area > 30)
    AllRegionsValid := 0
    break
  endif
endfor

结果

break（作为算子）总是返回2（H_MSG_TRUE）。

备选

continue
