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

The parameter QueryNameQueryNameQueryNameQueryNamequeryNamequery_name is used to select the desired parameter group:

例程 (HDevelop)

* This example demonstrates how the names of all available model parameters
* can be queried.  This is used to request first the settings of the
* untrained and then the settings of the trained model.

* Create a model for reading Data matrix ECC 200 codes
create_data_code_2d_model ('Data Matrix ECC 200', [], [], DataCodeHandle)
* Query all the names of the generic parameters that can be passed to the
* operator get_data_code_2d_param to request the model
query_data_code_2d_params (DataCodeHandle, 'get_model_params', GenParamName)
* Request the current settings of the (untrained) model
get_data_code_2d_param(DataCodeHandle, GenParamName, ModelParams)

* 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)
* Request the current settings of the (now trained) model
get_data_code_2d_param(DataCodeHandle, GenParamName, TrainedModelParams)
* Create a tuple that demonstrates the changings
ModelAdaption := GenParamName + ':   ' + ModelParams + '  ->  ' + \
                 TrainedModelParams

* Clear the model
clear_data_code_2d_model (DataCodeHandle)
