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 NULL, otherwise TESSDATA_PREFIX is used if not NULL, next try to use compiled in -DTESSDATA_PREFIX. If previous is not sucessul - use current directory.
basename- name of image

< name of image

< data directory
