write_class_knn — Save the k-NN classifier in a file.
write_class_knn writes the k-NN classifier KNNHandle to the file given by FileName. The classifier can be read again with read_class_knn. Since the samples are an intrinsic component of a k-NN-classifier, the operator write_class_knn saves them within the class file. In contrast to other classifiers like SVM, there is no operator for saving the samples separately. The samples can be retrieved from a k-NN-classifier using get_sample_class_knn. The default HALCON file extension for the k-NN classifier is 'gnc'.
Handle of the k-NN classifier.
Name of the file in which the classifier will be written.
File extension: .gnc
write_class_knn returns 2 (H_MSG_TRUE). An exception is raised if it was not possible to open file FileName.
