You need to use leptonica (e.g. via ctypes, but there is also python
module pylepthonica).
Modify relevant part of script with something like this:
lep = ctypes.cdll.LoadLibrary("liblept.so")
pix_image = lep.pixRead(filename)print "image width:",
lep.pixGetWidth(pix_image)print "image height:",
lep.pixGetHeight(pix_image)
tesseract.TessBaseAPISetImage2(api, pix_image)
tesseract.TessBaseAPISetRectangle(api, 30, 60, 400, 100)
text_out = tesseract.TessBaseAPIGetUTF8Text(api)
result_text = ctypes.string_at(text_out)print result_text
