I am using the tesseract capi from Python using ctypes. Everything seems to
work well except multi-page TIFFs. I only get text from the last page
instead of all the text in a multi-page TIFF.
This is what I'm doing:
path = "multipage.tiff"
self.tesseract.TessBaseAPIProcessPages.argtypes =
[POINTER(TessBaseAPI), c_char_p, c_char_p, c_int,
POINTER(TessResultRenderer)]
self.tesseract.TessBaseAPIProcessPages.restype = c_bool
success = self.tesseract.TessBaseAPIProcessPages(self.api,
create_string_buffer(path), None , 0, None)
ocr_r = self.tesseract.TessBaseAPIGetUTF8Text(self.api)
result = string_at(ocr_r) #contains text only from last page
Has anyone come across this before or have knowledge of how to resolve
this?
I had [opened this as an issue][1] in tesseract but apparently this isn't
an issue in tesseract command line or API since the command line works fine
and gives text for all pages.
Perhaps something else should be called instead of
`self.tesseract.TessBaseAPIGetUTF8Text(api)` to get all the text?
