write_contour_xld_arc_infowrite_contour_xld_arc_infoWriteContourXldArcInfoWriteContourXldArcInfowrite_contour_xld_arc_info (Operator)
Name
write_contour_xld_arc_infowrite_contour_xld_arc_infoWriteContourXldArcInfoWriteContourXldArcInfowrite_contour_xld_arc_info — Write XLD contours to a file in ARC/INFO generate format.
Signature
Herror write_contour_xld_arc_info(const Hobject Contours, const char* FileName)
Herror T_write_contour_xld_arc_info(const Hobject Contours, const Htuple FileName)
Description
write_contour_xld_arc_infowrite_contour_xld_arc_infoWriteContourXldArcInfoWriteContourXldArcInfowrite_contour_xld_arc_info writes the XLD contours
ContoursContoursContourscontourscontours to an ARC/INFO generate format file with name
FileNameFileNameFileNamefileNamefile_name. If no absolute path is given in
FileNameFileNameFileNamefileNamefile_name, the output file is created in the current
directory of the HALCON process. The contours must have been
transformed to the world coordinate system with
affine_trans_contour_xldaffine_trans_contour_xldAffineTransContourXldAffineTransContourXldaffine_trans_contour_xld beforehand. The necessary
transformation can be read from an ARC/INFO world file with
read_world_fileread_world_fileReadWorldFileReadWorldFileread_world_file.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Parameters
ContoursContoursContourscontourscontours (input_object) xld_cont(-array) → objectHXLDContHObjectHObjectHobject
XLD contours to be written.
FileNameFileNameFileNamefileNamefile_name (input_control) filename.write → HTuplestrHTupleHtuple (string) (string) (HString) (char*)
Name of the ARC/INFO file.
Example (HDevelop)
* Read transformation and image
read_world_file ('image.tfw', WorldTransformation)
read_image (Image, 'image.tif')
* Segment image
* ...
* Write result
affine_trans_contour_xld (Contours, ContoursWorld, WorldTransformation)
write_contour_xld_arc_info (ContoursWorld, 'result.gen')
Result
If the parameters are correct and the file could be written, the
operator write_contour_xld_arc_infowrite_contour_xld_arc_infoWriteContourXldArcInfoWriteContourXldArcInfowrite_contour_xld_arc_info returns the value 2 (
H_MSG_TRUE)
.
Otherwise an exception is raised.
