Description

The operator read_bar_code_modelread_bar_code_modelReadBarCodeModelReadBarCodeModelReadBarCodeModel reads the bar code model from the file FileNameFileNameFileNameFileNamefileName and creates a new model that is an identical copy of the saved model. The parameter BarCodeHandleBarCodeHandleBarCodeHandleBarCodeHandlebarCodeHandle returns the handle of the new model. The model file FileNameFileNameFileNameFileNamefileName must have been created by the operator write_bar_code_modelwrite_bar_code_modelWriteBarCodeModelWriteBarCodeModelWriteBarCodeModel. The default HALCON file extension for bar code model is 'bcm'.
