Description

The operator get_bar_code_param_specificget_bar_code_param_specificGetBarCodeParamSpecificGetBarCodeParamSpecificGetBarCodeParamSpecificget_bar_code_param_specific allows to query parameters of a bar code model, which are of relevance for a successful search and decoding of a respective class of bar codes. Contrary to get_bar_code_paramget_bar_code_paramGetBarCodeParamGetBarCodeParamGetBarCodeParamget_bar_code_param, get_bar_code_param_specificget_bar_code_param_specificGetBarCodeParamSpecificGetBarCodeParamSpecificGetBarCodeParamSpecificget_bar_code_param_specific allows a bar code type specific query for the following parameters. This is useful when searching different code types in one image. The bar code types are specified in CodeTypesCodeTypesCodeTypesCodeTypescodeTypescode_types. The names of the desired parameters are passed in the generic parameter GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name and the corresponding values are returned in GenParamValueGenParamValueGenParamValueGenParamValuegenParamValuegen_param_value. All of these parameters can be set and changed selectively with the operator set_bar_code_param_specificset_bar_code_param_specificSetBarCodeParamSpecificSetBarCodeParamSpecificSetBarCodeParamSpecificset_bar_code_param_specific or for all bar code types with the operator set_bar_code_paramset_bar_code_paramSetBarCodeParamSetBarCodeParamSetBarCodeParamset_bar_code_param. Which parameters are set specifically can be determined at runtime with the operator query_bar_code_paramsquery_bar_code_paramsQueryBarCodeParamsQueryBarCodeParamsQueryBarCodeParamsquery_bar_code_params. These parameters cannot be read with get_bar_code_paramget_bar_code_paramGetBarCodeParamGetBarCodeParamGetBarCodeParamget_bar_code_param, but must be read with get_bar_code_param_specificget_bar_code_param_specificGetBarCodeParamSpecificGetBarCodeParamSpecificGetBarCodeParamSpecificget_bar_code_param_specific.

The following parameters can be queried:

'num_scanlines'"num_scanlines""num_scanlines""num_scanlines""num_scanlines""num_scanlines":

Maximal number of scanlines used during the scanning of a (candidate) bar code.

'min_identical_scanlines'"min_identical_scanlines""min_identical_scanlines""min_identical_scanlines""min_identical_scanlines""min_identical_scanlines":

Minimal number of decoded scanlines which return identical data to read the bar code successfully.

'stop_after_result_num'"stop_after_result_num""stop_after_result_num""stop_after_result_num""stop_after_result_num""stop_after_result_num":

Number of successfully decoded bar codes of the given code type after which the decoding will stop. 0 is the default where the reader tries to decode all candidates.

'orientation'"orientation""orientation""orientation""orientation""orientation":

Accepted orientation of the decoded bar codes.

'orientation_tol'"orientation_tol""orientation_tol""orientation_tol""orientation_tol""orientation_tol":

Tolerance of the accepted orientation.

'quiet_zone'"quiet_zone""quiet_zone""quiet_zone""quiet_zone""quiet_zone":

Quiet zone verification mode.

'start_stop_tolerance'"start_stop_tolerance""start_stop_tolerance""start_stop_tolerance""start_stop_tolerance""start_stop_tolerance":

Start/stop search criteria tolerance. Currently it is implemented only for Code 128 and GS1-128.

'check_char'"check_char""check_char""check_char""check_char""check_char":

Handling of an optional check character.

'composite_code'"composite_code""composite_code""composite_code""composite_code""composite_code":

Presence and type of a 2D composite code appended to the bar code.

'min_code_length'"min_code_length""min_code_length""min_code_length""min_code_length""min_code_length":

Minimal number of decoded characters.

'max_code_length'"max_code_length""max_code_length""max_code_length""max_code_length""max_code_length":

Maximum number of decoded characters.
