Description

read_measureread_measureReadMeasureReadMeasureReadMeasure reads a measure object, which has been written with write_measurewrite_measureWriteMeasureWriteMeasureWriteMeasure from the file FileNameFileNameFileNameFileNamefileName. The default HALCON file extension for a measure object is 'msr'.
