[ocr_localizer] OCRLocalizer::compose() has ambiguous arguments interface

[roricljy]

In the code:

DeepGuider/src/ocr_recog/ocr_localizer.hpp

Line 249 in 9e61aa4

wchar_t compose(wchar_t chosung, wchar_t jungsung, wchar_t jongsung)

The arguments wchar_t chosung, wchar_t jungsung, wchar_t jongsung seems to be Korean unit characters to be composed, but used as array indices in the body of function implementation.

It seems that the current implementation does not work.
One possible implementation would be:

wchar_t compose(wchar_t chosung, wchar_t jungsung, wchar_t jongsung)
{
	setlocale(LC_ALL, "KOREAN");

	int cho_idx = 0;
	int cho_max = sizeof(chosung_list) / sizeof(wchar_t);
	while (chosung_list[cho_idx] != chosung && cho_idx < cho_max) cho_idx++;

	int jung_idx = 0;
	int jung_max = sizeof(jungsung_list) / sizeof(wchar_t);
	while (jungsung_list[jung_idx] != jungsung && jung_idx < jung_max) jung_idx++;

	int jong_idx = 0;
	int jong_max = sizeof(jongsung_list) / sizeof(wchar_t);
	while (jongsung_list[jong_idx] != jongsung && jong_idx < jong_max) jong_idx++;

	if (cho_idx >= cho_max || jung_idx >= jung_max || jong_idx >= jong_max)
	{
		printf("OCRLocalizer::compose() - invalid input character!\n");
		return 0;
	}

	wchar_t character = (wchar_t)(kor_begin + chosung_base * cho_idx + jungsung_base * jung_idx + jong_idx);

	return character;
}
