描述

算子 set_spyset_spySetSpySetSpySetSpyset_spy is the HALCON debugging tool. This tool allows the flexible control of the input and output data of HALCON-operators - in graphical as well as in textual form. The data control is activated by using

set_spy(::'mode','on':)set_spy("mode","on")SetSpy("mode","on")SetSpy("mode","on")SetSpy("mode","on")set_spy("mode","on"),

and deactivated by using

set_spy(::'mode','off':)set_spy("mode","off")SetSpy("mode","off")SetSpy("mode","off")SetSpy("mode","off")set_spy("mode","off").

The debugging tool can further be activated with the help of the environment variable HALCONSPY. The definition of this variable corresponds to calling up 'mode'"mode""mode""mode""mode""mode" and 'on'"on""on""on""on""on".

The following control modes (ClassClassClassClassclassValclass) can be tuned using ValueValueValueValuevaluevalue:

ClassClassClassClassclassValclass = 'operator'"operator""operator""operator""operator""operator"

When a routine is called, its name and the names of its parameters will be given (in TRIAS notation).

ValueValueValueValuevaluevalue: 'on'"on""on""on""on""on" or 'off'"off""off""off""off""off".

Default: 'off'"off""off""off""off""off".

ClassClassClassClassclassValclass = 'input_control'"input_control""input_control""input_control""input_control""input_control"

When a routine is called, the names and values of the input control parameters will be given.

ValueValueValueValuevaluevalue: 'on'"on""on""on""on""on" or 'off'"off""off""off""off""off".

Default: 'off'"off""off""off""off""off".

ClassClassClassClassclassValclass = 'output_control'"output_control""output_control""output_control""output_control""output_control"

When a routine is called, the names and values of the output control parameters are given.

ValueValueValueValuevaluevalue: 'on'"on""on""on""on""on" or 'off'"off""off""off""off""off".

Default: 'off'"off""off""off""off""off".

ClassClassClassClassclassValclass = 'parameter_values'"parameter_values""parameter_values""parameter_values""parameter_values""parameter_values"

Additional information on 'input_control'"input_control""input_control""input_control""input_control""input_control" and 'output_control'"output_control""output_control""output_control""output_control""output_control"：indicates how many values per parameter shall be displayed at most (maximum tuple length of the output).

ValueValueValueValuevaluevalue: tuple length (integer)

Default: 4

ClassClassClassClassclassValclass = 'db'"db""db""db""db""db"

Information concerning the 4 relations in the HALCON-database. This is especially valuable in looking for forgotten clear_objclear_objClearObjClearObjClearObjclear_obj。

ValueValueValueValuevaluevalue: 'on'"on""on""on""on""on" or 'off'"off""off""off""off""off".

Default: 'off'"off""off""off""off""off".

ClassClassClassClassclassValclass = 'time'"time""time""time""time""time"

Processing time of the operator

ValueValueValueValuevaluevalue: 'on'"on""on""on""on""on" or 'off'"off""off""off""off""off".

Default: 'off'"off""off""off""off""off".

ClassClassClassClassclassValclass = 'log_file'"log_file""log_file""log_file""log_file""log_file"

Spy can hereby divert the text output into a file having been opened with open_file.

ValueValueValueValuevaluevalue: a file handle (see open_fileopen_fileOpenFileOpenFileOpenFileopen_file)

ClassClassClassClassclassValclass = 'error'"error""error""error""error""error"

If 'error'"error""error""error""error""error" is activated and an internal error occurs, spy will show the internal procedures (file/line) concerned.

ValueValueValueValuevaluevalue: 'on'"on""on""on""on""on" or 'off'"off""off""off""off""off".

Default: 'off'"off""off""off""off""off".

ClassClassClassClassclassValclass = 'internal'"internal""internal""internal""internal""internal"

If 'internal'"internal""internal""internal""internal""internal" is activated, spy will display the internal procedures and their parameters (file/line) while an HALCON-operator is processed.

ValueValueValueValuevaluevalue: 'on'"on""on""on""on""on" or 'off'"off""off""off""off""off".

Default: 'off'"off""off""off""off""off".

Each output starts with the thread handle, followed by a global counter that marks the order of the outputs. In multi-threaded applications, this information can be used to assign the output to individual user threads and to reconstruct the chronological sequence.

注意

Note that under Windows the output on stdout works only in combination with a console application.

执行信息

• 多线程类型：独占（仅与独立算子并行运行）。
• 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

示例（C）

/* init spy: Setting of the wished control modi */
set_spy("mode","on");
set_spy("operator","on");

/* calling of program section, that will be examined */
set_spy("mode","off");  

结果

算子 set_spyset_spySetSpySetSpySetSpyset_spy 在参数正确时返回值 2 ( H_MSG_TRUE )。否则将抛出异常。
