Name
read_ocr_class_svmT_read_ocr_class_svmReadOcrClassSvmReadOcrClassSvmread_ocr_class_svm — Read a SVM-based OCR classifier from a file.
Signature
def read_ocr_class_svm(file_name: str) -> HHandle
Description
read_ocr_class_svmread_ocr_class_svmReadOcrClassSvmReadOcrClassSvmReadOcrClassSvmread_ocr_class_svm reads an OCR classifier that has been
stored with write_ocr_class_svmwrite_ocr_class_svmWriteOcrClassSvmWriteOcrClassSvmWriteOcrClassSvmwrite_ocr_class_svm. Since the training of an
OCR classifier can consume a relatively long time, the classifier is
typically trained in an offline process and written to a file with
write_ocr_class_svmwrite_ocr_class_svmWriteOcrClassSvmWriteOcrClassSvmWriteOcrClassSvmwrite_ocr_class_svm. In the online process the classifier is
read with read_ocr_class_svmread_ocr_class_svmReadOcrClassSvmReadOcrClassSvmReadOcrClassSvmread_ocr_class_svm and subsequently used for
classification with do_ocr_single_class_svmdo_ocr_single_class_svmDoOcrSingleClassSvmDoOcrSingleClassSvmDoOcrSingleClassSvmdo_ocr_single_class_svm or

Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.
Parameters
FileNameFileNameFileNameFileNamefileNamefile_name (input_control) filename.read → HTuplestrHTupleHtuple (string) (string) (HString) (char*)
File name.
File extension: .osc, .fnt
OCRHandleOCRHandleOCRHandleOCRHandleOCRHandleocrhandle (output_control) ocr_svm → HOCRSvm, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)
Handle of the OCR classifier.
Result
If the parameters are valid the operator read_ocr_class_svmread_ocr_class_svmReadOcrClassSvmReadOcrClassSvmReadOcrClassSvmread_ocr_class_svm
returns the value 2 (H_MSG_TRUE). If necessary, an exception is
raised.
