issue with extract_text

[rsteca]

When doing:

import doc2text
doc = doc2text.Document()
doc.read('something.pdf')
doc.process()
doc.extract_text()

I get the following error:

AttributeError                            Traceback (most recent call last)

     92                 self.page_content.append(text)
     93         else:

     39         self.text = pytesseract.image_to_string(Image.open(temp_path))
     40         os.remove(temp_path)

AttributeError: Page instance has no attribute 'image'
