Read a 2D data code model from a file and create a new model.
The operator read_data_code_2d_model reads the 2D data code model file FileName and creates a new model that is an identical copy of the saved model. The parameter DataCodeHandle returns the handle of the new model. The model file FileName must be created by the operator write_data_code_2d_model.
|
FileName (input_control) |
string -> string |
| Name of the 2D data code model file. | |
| Default value: 'data_code_model.dcm' | |
|
DataCodeHandle (output_control) |
datacode_2d -> integer |
| Handle of the created 2D data code model. | |
* This example demonstrates how a model that was saved in an earlier
* session can be used again by reading the model file
* Create a model by reading by reading a data code model file
read_data_code_2d_model ('ecc200_trained_model.dcm', DataCodeHandle)
* Read a symbol image
read_image (Image, 'datacode/ecc200/ecc200_cpu_010')
* Read the symbol in the image
find_data_code_2d (Image, SymbolXLDs, DataCodeHandle, [], [],
ResultHandles, DecodedDataStrings)
* Clear the model
clear_data_code_2d_model (DataCodeHandle)
The operator read_data_code_2d_model returns the value 2 (H_MSG_TRUE) if the named 2D data code file was found and correctly read. Otherwise, an exception will be raised.
read_data_code_2d_model is processed completely exclusively without parallelization.
