5:get_data_code_2d_objects( : DataCodeObjects : DataCodeHandle, CandidateHandle, ObjectName : )功能：Access iconic objects that were created during the search for 2D data code symbols.访问图标对象-------------这些对象已经在浏览条码符号的过程中。

DataCodeHandle (input_control) datacode_2d →(integer)2维码数据模型的句柄CandidateHandle (input_control) integer →(integer / string)所需图标的类型做为条件逻辑Default value: 'all_candidates'Suggested values: 0, 1, 2, 'all_candidates', 'all_results', 'all_undecoded', 'all_aborted'ObjectName (input_control) string →(string)输入图标对象的名称。
Default value: 'candidate_xld'List of values: 'module_1_rois', 'module_0_rois', 'candidate_xld', 'search_image', 'process_image':下列对象可以返回：Regions of the modules'module_1_rois':All modules that were classified as foreground (set).'module_0_rois':All modules that were classified as background (not set).These region arrays correspond to the areas that were used for the classification. The returned object is a region array. Hence it cannot be requested for a group of candidates. Therefore, a single result handle must be passed in CandidateHandle. The model persistence must be 1 for this object. In addition, requesting the module ROIs makes sense only for symbols that were detected as valid symbols. For other candidates, whose processing was aborted earlier, the module ROIs are not available.XLD contour'candidate_xld':An XLD contour that surrounds the candidate or decoded symbol.This object can be requested for any group of results or for any single candidate or symbol handle. The persistence setting is of no relevance.Pyramid images'search_image':Pyramid image, in which the candidate was found.'process_image':Pyramid image, in which the candidate was investigated more closely. ———————————————————————————6:get_data_code_2d_param( : : DataCodeHandle, GenParamNames : GenParamValues)功能：Get one or several parameters that describe the 2D data code model.取得一个或多个参数-----------和2D数据码模型相关参数：DataCodeHandle (input_control) datacode_2d →(integer)二维数据码模型句柄GenParamNames (input_control) (-array) →(string)Names of the generic parameters that are to be queried for the 2D data code model.获得数据码所需的参数的名称Default value: 'contrast_min'List of values: 'strict_model', 'persistence', 'polarity', 'mirrored', 'contrast_min', 'model_type', 'version_min', 'version_max', 'symbol_size_min', 'symbol_size_max', 'symbol_cols_min', 'symbol_cols_max', 'symbol_rows_min', 'symbol_rows_max', 'symbol_shape', 'module_size_min', 'module_size_max', 'module_width_min', 'module_width_max', 'small_modules_robustness', 'module_aspect_min', 'module_aspect_max', 'module_gap_col_min', 'module_gap_col_max', 'module_gap_row_min', 'module_gap_row_max', 'slant_max', 'module_grid', 'position_pattern_min', 'finder_pattern_tolerance'GenParamValues (output_control) attribute.value(-array) →(string / integer / real)参数的值。
