Description

get_params_ocr_class_svmget_params_ocr_class_svmGetParamsOcrClassSvmGetParamsOcrClassSvmGetParamsOcrClassSvm returns the parameters of an OCR classifier that were specified when the classifier was created with create_ocr_class_svmcreate_ocr_class_svmCreateOcrClassSvmCreateOcrClassSvmCreateOcrClassSvm. This is particularly useful if the classifier was read with read_ocr_class_svmread_ocr_class_svmReadOcrClassSvmReadOcrClassSvmReadOcrClassSvm. The output of get_params_ocr_class_svmget_params_ocr_class_svmGetParamsOcrClassSvmGetParamsOcrClassSvmGetParamsOcrClassSvm can, for example, be used to check whether a character to be read is contained in the classifier. For a description of the parameters, see create_ocr_class_svmcreate_ocr_class_svmCreateOcrClassSvmCreateOcrClassSvmCreateOcrClassSvm.

Result

If the parameters are valid the operator get_params_ocr_class_svmget_params_ocr_class_svmGetParamsOcrClassSvmGetParamsOcrClassSvmGetParamsOcrClassSvm returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.
