Short description🔗

read_measureReadMeasureReadMeasureread_measureT_read_measure — Read a measure object from a file.

Signature🔗

Herror T_read_measure( const Htuple FileName, Htuple* MeasureHandle )

void HMeasure::ReadMeasure( const HString& FileName )

void HMeasure::ReadMeasure( const char* FileName )

void HMeasure::ReadMeasure( const wchar_t* FileName ) (Windows only)

void HMeasure.ReadMeasure( string fileName )

Description🔗

read_measureReadMeasure reads a measure object, which has been written with write_measureWriteMeasure from the file FileNamefileNamefile_name. The default HALCON file extension for a measure object is 'msr'. The values contained in the read measure object are stored in a measure object with the handle MeasureHandlemeasureHandlemeasure_handle.

For an explanation of the concept of 1D measuring see the introduction of chapter 1D Measuring.

Execution information🔗

Execution information

  • Multithreading type: reentrant (runs in parallel with non-exclusive operators).

  • Multithreading scope: global (may be called from any thread).

  • Processed without parallelization.

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.

Parameters🔗

FileNamefileNamefile_name (input_control) filename.read → (string)HTuple (HString)HTuple (string)strHtuple (char*)

File name.

File extension: .msr

MeasureHandlemeasureHandlemeasure_handle (output_control) measure → (handle)HTuple (HHandle)HMeasure, HTuple (IntPtr)HHandleHtuple (handle)

Measure object handle.

Result🔗

If the parameters are valid, the operator read_measureReadMeasure returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.
