write_data_code_2d_modelT_write_data_code_2d_modelWriteDataCode2dModelWriteDataCode2dModel (Operator)

Name

write_data_code_2d_modelT_write_data_code_2d_modelWriteDataCode2dModelWriteDataCode2dModel — Writes a 2D data code model into a file.

Signature

Description

The operator write_data_code_2d_modelwrite_data_code_2d_modelWriteDataCode2dModelWriteDataCode2dModelWriteDataCode2dModel writes a 2D data code model, which was created by create_data_code_2d_modelcreate_data_code_2d_modelCreateDataCode2dModelCreateDataCode2dModelCreateDataCode2dModel, into a file with the name FileNameFileNameFileNameFileNamefileName. This facilitates creating an identical copy of the saved model in a later session with the operator read_data_code_2d_modelread_data_code_2d_modelReadDataCode2dModelReadDataCode2dModelReadDataCode2dModel. The default HALCON file extension for the 2D data code model is 'dcm'. The handle of the model to write is passed in DataCodeHandleDataCodeHandleDataCodeHandleDataCodeHandledataCodeHandle.

For an explanation of the concept of the 2D data code reader see the introduction of chapter Identification / Data Code.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

Parameters

Example (HDevelop)

* This example demonstrates how a trained model can be saved for
* a future session

* Create a model for reading Data matrix ECC 200 codes
create_data_code_2d_model ('Data Matrix ECC 200', [], [], DataCodeHandle)
* Read a training image
read_image (Image, 'datacode/ecc200/ecc200_cpu_007')
* Train the model with the symbol in the image
find_data_code_2d (Image, SymbolXLDs, DataCodeHandle, 'train', 'all', \
                   ResultHandles, DecodedDataStrings)
* Write the model into a file
write_data_code_2d_model (DataCodeHandle, 'ecc200_trained_model.dcm')
* Clear the model
clear_data_code_2d_model (DataCodeHandle)

Result

The operator write_data_code_2d_modelwrite_data_code_2d_modelWriteDataCode2dModelWriteDataCode2dModelWriteDataCode2dModel returns the value 2 (H_MSG_TRUE) if the passed handle is valid and if the model can be written into the named file. Otherwise, an exception is raised.
