Warning

write_class_boxwrite_class_boxWriteClassBoxWriteClassBoxwrite_class_box is obsolete and is only provided for reasons of backward compatibility. New applications should use the MLP, SVM, KNN or GMM operators instead. The operator will be removed with HALCON 25.11.

def write_class_box(classif_handle: HHandle, file_name: str) -> None

Description

write_class_boxwrite_class_boxWriteClassBoxWriteClassBoxwrite_class_box writes the classifier ClassifHandleClassifHandleClassifHandleclassifHandleclassif_handle to the file given by FileNameFileNameFileNamefileNamefile_name. The classifier can be read with read_class_boxread_class_boxReadClassBoxReadClassBoxread_class_box. The default HALCON file extension for the box classifier is 'gbc'.

Attention

If a file with this name exists, it is overwritten without a warning. The file can not be edited.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

Parameters
