名称

write_polygon_xld_arc_infowrite_polygon_xld_arc_infoWritePolygonXldArcInfoWritePolygonXldArcInfowrite_polygon_xld_arc_info — 将 XLD 多边形以 ARC/INFO 生成格式写入文件。

write_polygon_xld_arc_info(Polygons : : FileName : )

描述

write_polygon_xld_arc_infowrite_polygon_xld_arc_infoWritePolygonXldArcInfoWritePolygonXldArcInfoWritePolygonXldArcInfowrite_polygon_xld_arc_info writes the XLD polygons PolygonsPolygonsPolygonsPolygonspolygonspolygons to an ARC/INFO generate format file with name FileNameFileNameFileNameFileNamefileNamefile_name. If no absolute path is given in FileNameFileNameFileNameFileNamefileNamefile_name, the output file is created in the current directory of the HALCON process. The polygons must have been transformed to the world coordinate system with affine_trans_polygon_xldaffine_trans_polygon_xldAffineTransPolygonXldAffineTransPolygonXldAffineTransPolygonXldaffine_trans_polygon_xld beforehand. The necessary transformation can be read from an ARC/INFO world file with read_world_fileread_world_fileReadWorldFileReadWorldFileReadWorldFileread_world_file。

注意

The XLD contours that are possibly referenced by PolygonsPolygonsPolygonsPolygonspolygonspolygons are not stored in the ARC/INFO file, since this is not possible with the ARC/INFO generate file format. Therefore, when the polygons are read again using read_polygon_xld_arc_inforead_polygon_xld_arc_infoReadPolygonXldArcInfoReadPolygonXldArcInfoReadPolygonXldArcInforead_polygon_xld_arc_info, this information is lost, and no references to contours are generated for the polygons. Hence, operators that access the contours associated with a polygon, e.g., split_contours_xldsplit_contours_xldSplitContoursXldSplitContoursXldSplitContoursXldsplit_contours_xld will not work correctly.

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）。
未采用并行化处理。

参数

PolygonsPolygonsPolygonsPolygonspolygonspolygons (输入对象) xld_poly(-array) → object

XLD polygons to be written.

FileNameFileNameFileNameFileNamefileNamefile_name (输入控制) filename.write → (string)

Name of the ARC/INFO file.

示例（HDevelop）

* Read transformation and image
read_world_file ('image.tfw', WorldTransformation)
read_image (Image, 'image.tif')
* Segment image
* ...
* Write result
affine_trans_polygon_xld (Polygons, PolygonsWorld, WorldTransformation)
write_polygon_xld_arc_info (PolygonsWorld, 'result.gen')

结果

If the parameters are correct and the file could be written, the operator write_polygon_xld_arc_infowrite_polygon_xld_arc_infoWritePolygonXldArcInfoWritePolygonXldArcInfoWritePolygonXldArcInfowrite_polygon_xld_arc_info 返回值 2 ( H_MSG_TRUE )。否则将抛出异常。
