def info_ocr_class_box(ocr_handle: HHandle) -> Tuple[int, int, int, int, int, Sequence[str], Sequence[str]]
Description
The operator info_ocr_class_boxinfo_ocr_class_boxInfoOcrClassBoxInfoOcrClassBoxinfo_ocr_class_box returns some information
about an OCR classifier.
The parameters are equivalent to those of create_ocr_class_boxcreate_ocr_class_boxCreateOcrClassBoxCreateOcrClassBoxcreate_ocr_class_box.
The parameters WidthMaxCharWidthMaxCharWidthMaxCharwidthMaxCharwidth_max_char and HeightMaxCharHeightMaxCharHeightMaxCharheightMaxCharheight_max_char
indicate the extension of the largest trained character.
These values can be used to control the segmentation.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.

printf("MaxChar: %d x %d\n",get_i(WidthMaxChar,0),get_i(HeightMaxChar,0));
printf("Interpolation: %d\n",get_i(Interpolation,0));
printf("Features: ");
for (i=0; i<length_tuple(Features); i++)
printf("%s ",get_s(Features,i));
printf("\n");
printf("Characters: ");
for (i=0; i<length_tuple(Characters); i++)
printf(" %d %s\n",i,get_s(Characters,i));
Result
The operator info_ocr_class_boxinfo_ocr_class_boxInfoOcrClassBoxInfoOcrClassBoxinfo_ocr_class_box always returns 2 (
H_MSG_TRUE)
.
