read_measureT_read_measureReadMeasureReadMeasureread_measure (Operator)
Name
read_measureT_read_measureReadMeasureReadMeasureread_measure — Read a measure object from a file.
Signature
Description
read_measureread_measureReadMeasureReadMeasureReadMeasureread_measure reads a measure object, which has
been written with write_measurewrite_measureWriteMeasureWriteMeasureWriteMeasurewrite_measure from
the file FileNameFileNameFileNameFileNamefileNamefile_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 MeasureHandleMeasureHandleMeasureHandleMeasureHandlemeasureHandlemeasure_handle.
For an explanation of the concept of 1D measuring see the introduction of
chapter 1D Measuring.
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
FileNameFileNameFileNameFileNamefileNamefile_name (input_control) filename.read → HTuplestrHTupleHtuple (string) (string) (HString) (char*)
File name.
File extension:
.msr
MeasureHandleMeasureHandleMeasureHandleMeasureHandlemeasureHandlemeasure_handle (output_control) measure → HMeasure, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

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