  • tried that option as well. not working when psm=ITessAPI.TessPageSegMode.PSM_AUTO is used. Works with psm = -1 – SIVAPRIYA V Jun 26 '15 at 10:40
  • This usually indicates you're passing a buffer to the native code that is invalid (might be already freed, might be too small). Verify that all your parameters are sane when you enter `TessBaseAPIGetUTF8Text`. – technomage Jun 26 '15 at 11:59
  • Make sure your Java architecture matches your Windows architecture. – mhcuervo Apr 08 '16 at 07:13
