main_setup()

void tesseract::CCUtil::main_setup	(	const char *	argv0,
		const char *	basename
	)

CCUtil::main_setup - set location of tessdata and name of image.

Parameters

argv0	- paths to the directory with language files and config files. An actual value of argv0 is used if not nullptr, otherwise TESSDATA_PREFIX is used if not nullptr, next try to use compiled in -DTESSDATA_PREFIX. If previous is not successful - use current directory.
basename	- name of image

< name of image
